SD card woes
Hi all, I am experiencing problems with the TE2 and SD-cards. When an application writes too many files into a directory the directory may get corrupted. This happens e.g. with many 512MB cards when say 200 files with 1K of text each are written with VFSFileOpen/-Write/-Close. Suddenly the directory shows dozens of garbage entries like ñ7y+õÅ■.N à 271614 KB 27.03.2074 23:45 ÛZ T.Ûý,.Öbj 3776489 KB07.08.1993 01:48 -4=--.l./'Directory It seems the VFS layer or the corresponding FS-lib play havoc with the directory. Alas I cannot ask the user to format those SD cards out in the field. I need to gracefully repair them by removing/deleting those 'fragments' or by deleting the directory that was corrupted. Unfortunatley the VFS/FSLib functions cannot delete those entries because the file names are invalid. Neither can I delete the corrupt directory because it is not emtpy. Any ideas on how to get rid of this garbage without formatting the entire card?

re: Recovering PDBs from NVRAM in a dead T5
Hi Luc, if he is lucky it is not the mainboard causing the white screen. In say 50% of white screen cases we are able to resurrect the device with the following steps: 1. take out the battery (it is solded on the T5) 1.1 reconnect and try to boot with the same battery 1.2 try to boot with another fully charged battery (don't ask me why but I have seen E2s turning white with one battery and running perfectly with another) 2. try to boot with annother LCD module, taken from a TX or T5 (remove battery during operation!) 3. inspect the mainboard for corrosion with a magnifing glass (battery removed!). If you find some, carefully brush off the crystals with a glass fibre brush and some electronics cleaner. Good luck!

Re: SCOOP: New GarnetOS (PalmOS) Handhelds Coming From Aceeca!
Benjamin is right, the digitizers built in from 2007 on are of lousy quality. It's probably the indium tin oxide coating that is of poor quality. I could pick a few hundreds of bad digis from our bin and send them to you ... I doubt you can fix a whole in the ITO surfacing with a better driver because the behaviour is non-linear (i.e. chaotic)... Harry -- You are kidding right? They tend to drift and then you go back and forth and back and forth hitting the target area after a hard reset. The only solution is to send it away for repair or replace the unit entirely.

RE: Classic emulator interface on Palm Pre
My 2 cents of wisdom on the digitizers: In my company we replace several dozens of them per day. And if we look at the manufacturing date we find that 90% of defect digitizers date from Q3/2007 till August 2008 (end of production). Just today I saw a device from early 2008 that was RMA-ed in late 2008, got a new digitizer from Palm and now is sent back to us to get its 3rd one! On the other hand we get devices from 2005/2006 that just need a new battery with the digi being still 100% accurate. To me Palm have become more and more negligent on quality management in the last years of Tungsten/Zire production. That had cost them a lot of goodwill in our customer base. Initially our customers viewed Palm PDAs high quality, durable goods (in fact many of them had bought a Palm V, M515 e.a. before and those were still working after 3-5 years). As of today I still see demand for a EUR 150/USD 200 PDA that does not carry the additional cost and functionality overhead of a phone. However the global volume is certainly way too low to justify new development for a listed company like Palm. Hadn't they continuously shot themself in the foot (and they did so on any occasion, HW- and SW-wise) they might still be milking a small but profitable cash-cow. Harry Or you could import replacement digitizers from China, and fit them instead. That is much cheaper than PowerDigi, even for a 480 x 320 display. -Original Message- From: Dmitry Grinberg [mailto:dmitr...@gmail.com] Sent: 17 May 2009 18:56 To: Palm Developer Forum Subject: Re: Classic emulator interface on Palm Pre Or you could install PowerDiGi on them, which will make them align 100% of the time, and is both much cheaper than Janam and cheaper than a new device...

Random crash in Armlet via PCENativeCall
I finally started armlet-pogramming ;-) and run into what probably is a
beginners problem. The following small armlet randomly produces a Fat/Ex when
called with PceNativeCall:
/*** ARMLET CODE /
#include PalmOS.h
#include PceNativeCall.h
#include ByteOrderUtils.h
// parameters for the armlet
typedef struct {
UInt8* buff;
UInt32 buffSize;
UInt8 a;
UInt8 b;
} myParmType;
UInt32 ARMlet_Main( const void *emulStateP, myParmType*, Call68KFuncType* );
UInt32 ARMlet_Main( const void *emulStateP, myParmType *parm, Call68KFuncType
*call68KFuncP ) {
UInt8 *p, *pEnd, a, b;
p = (UInt8*) Read68KUnaligned32( (parm-buff) );
pEnd = p + Read68KUnaligned32( (parm-buffSize) );
a = parm-a;
b = parm-b;
do some computation on the buffer
}
return 0;
}
**
I am pretty sure the computation on the buffer data is ok because I use the
identical code in 68K on the simulator without any problem.
Anlignment of the parameter 'parm' doesn't matter: the docs say the parameter
for the armlet needn't be aligned. I also checked that putting 'parm' on a 1,2
or 3 byte boundary does not cause a crash.

Rare crash on an E2
Hey guys, my E2s show a very rare crash. When calling SysGetROMToken (0, sysROMTokenSnum, (UInt8**) ROMToken, len) my app throws a Fatal Exception.

Re: Rare crash on an E2
The ROM serial is not lost. I can still retrieve it on those devices after the normal reset that follows the Fat/Ex. My gut feeling is that it is related to the NAND flash. Maybe some funny wearing off of memory cells that produces read/write errors? It seems also, that devices that just had a hard-reset do not produce this error or maybe they produce it just later. -- For information on using the ACCESS Developer Forums, or to unsubscribe, please see http://www.access-company.com/developers/forums/

Re: Any known bugs in TimGetSeconds() or TimSecondsToDateTime()?

However, the system clock remains at 0 secs == 1.1.1904, 0:00 -- it's obviously not backed up to NVFS Case b) the battery or some other part of the internal power supply chain interrupts or goes down in erratic and unpredictable ways -- replace battery or entire unit in this case The catch here is with the NVFS devices: user often do not realise that power outage has occurred at all.

WinPaintChars() causes weird crash on Tungsten-E
Hi all, I am testing the new version of a multi-segment app and observe very rare and erratic crashes in the following code: Char message[] = some text constant; UInt16 len = StrLen( message ); RectangleType rect; ... WinSetDrawMode( winOverlay ); ... WinDrawRectangleFrame( simpleFrame, rect ); WinPaintChars( message, len, rect.topLeft.x + (rect.extent.x - FntCharsWidth(message, len))/2, rect.topLeft.y + (rect.extent.y - FntLineHeight())/2 - 1 ); The WinPaintChars() statement draws some text in the middle of a rectangle and does so as expected for maybe a 100 times, sometimes a 10,000 times before behaving completely erratic in either of the 3 ways: a) freezing the device b) throwing a Fatal Exception c) just *erasing* little rectangles from the background instead of painting the characters (but no freeze or exception) I have checked with the debugger the validity of message, len and the surrounding rectangle (all drawing and painting done in kCoordinatesNative). From cases a) and b) I can infer that it is WinPaintChars() that bombs (as the frame is drawn but the text does not get painted before the device hangs). Once case c) occurs, it keeps reoccurring every time the code is executed, i.e. it becomes a stable state in this segment. If I switch to annother form in another segment, WinPaintChars() behaves as expected; switching back to the first segment with the code seen above produces case c) again. Finally, if I quit and re-launch the application, everything is fine again for the next 100 or 10,000 calls of the code. Weird, isn't it?

re: preventing change to the palm clock / finding out the real time
This one's a lovely challenge! Here is a conceptual solution (no code). 1. Have your app schedule an alarm every 30 secs. (use AlmSetAlarm or AlmSetProcAlarm). Whenever your app. gets control via this alarm, it does two things: 1.1. compare TimGetSeconds() with a time stamp stored previously in step 1.2 (see below). If this delta is say 35 secs., you know the clock has been tampered with and reset is to the last time stamp + 15 secs. 1.2. if the check in 1.1. was ok, store the current system time at some reset-persistent place, e.g. a database record, an application preference. The nice thing is, even is the device is off (sleep mode), your app. will get the alarm and it can process it within a few cycles and without switching on the display - so the user won't notice this routine check. The impact on the power consumption of the device should be tolerable. If a user resets the device and changes the clock you just undo this change in a simple and effective way. The final question is, how long was the device in reset mode before your app regained control, i.e. how big is the delta between your stored timestamp and the actual time? Hint: the reset will set the SystemTicks back to 0; now if we take the currently elapsed ticks TimGetTicks()/TimTicksPerSecond() we have a good proxy for the actual time difference.

How to REALLY recalibrate the digitizer
Hi all! from time to time I need to recalibrate the digitizer from within my app. Unfortunately I cannot determine how to make the functions PenResetCalibration() and PenCalibrate() work properly. In principle, I take three pen-taps at top left, middle and bottom-right locations just like the built in welcome app. and then call PenCalibrate() -- so much for the theory. BUT: If I call PenResetCalibration() before that on a SONY Clie, the entire device hangs or makes the digitizer just plain dead -- the device does not accept any pen input. If I just call PenCalibrate() without a previous PenResetCalibration() it works fine on SONY clies and Palm Tungstens -- but only for the moment. If I quit the app or soft-reset the device, the entire calibration is skrewed up with screen and digitizer coordinates deviating wildly. As if the previous calibration were not stored properly. Does anybody know how those functions have to be applied, or how the logic of the built-in calibrator app. works? Maybe our esteemed insider Ben?

Database Search with Packed Records
I have read some of the posts regarding fast database searches. I am
wondering how fast search would be done with packed records, since I was
told and learned that record storage should be used with packed records.
However, I am not sure about how to do sorting with null terminated strings.
Here is an example of my structs:
struct{
int iD;
char * Text[];
}packedProduct;
struct{
int ID;
char* SKU;
char* UPC;

Generic Data Structures
Is it possible to create a generic data structure so that when you add more
columns to a record, you don't have to keep rewriting all the functions
associated with the struct?
Here is my example:
struct
{
Int16 ID;
*Char Name;
}Product
if I needed to add 1 more type or more, I always have to redifne my struct
and procedures, conduits etc.
{
Int16 ID;
*Char Name;
*Char Description;
}
I am wondering what techniques you can use to create generic structures
without having to rewrite all you structs and functions conduits. Any
examples or advice would be greatly appreciated.
Thanks!

Sample Hack code for prc-tools
Hi, I have a couple of hacks out there that don't work properly on non-monochrome devices, because I was a naughty boy a few years ago ... and, yes, I know, the current methods of writing hacks won't be supported in OS 5.0. Now that I've come back into Palm coding, I figured it was about time I cleaned them up. I'm using prc-tools on Linux, so can anyone point me at some sample source code that implements a hack using that environment? I found one called PLZ, but the comments are in German, which I don't speak, sadly.

Serial error
I'm trying to talk to a Magellan GPS sled for the Palm Vx. My load of the serial library works OK and my initialisation of the port (serDefaultSettings + 4800 baud) succeeds ... ie, they return zero. However, when I attempt to read from the port, via SerReceive10(), I get an error code of 774. According to errorcode.prc, this means ... serLineErr (Serial: line error(0x0306)) Can someone suggest what kinds of things could cause this error code to be returned? Any ideas on how to go about debugging it? I realise I'm using the old serial manager library. I'm happy to move to the new one if this problem is inherently to do with using the old one, but if not, I'd prefer to stick with this code, rather than having to write and debug some new code. I've used this code successfully to talk to the Palm sitting in its cradle, by copying /dev/tty into the appropriate serial port device (yes, I'm on Linux).

Re: POSE 3.4 memory leak question
What I don't understand is: 2) How can Poser tell this is a leak if the app hasn't ended? i.e. How does it know this is a leak as opposed to memory that I'm not finished using? I can't answer the other questions, but imagine if you had code like ... char *fred; fred = MemPtrNew(100); fred = MemPtrNew(100); One can tell this is a leak, even at runtime, because the only reference you had to the first allocated memory was fred. If you update fred to point somewhere else, it's obvious that there's no way you can ever get access to the original 100 bytes again. That said, I have no idea how Poser keeps track of stuff. I'm just pointing out that it's certainly possible to know at runtime if something like this is happening. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
Re: POSE 3.4 memory leak question
Hi Harry, I don't want to get into a big discussion about this, especially since I'm definitely no expert on the subject, but ... Thanks for the response. I agree that in a simple case like this it might be possible to detect a leak although I'm skeptical that Poser does this. In general, however, this type of determination is not possible. For example, consider fred = MemPtrNew(100); SomeFunc(fred); fred = MemPrtrNew(100); Is it still a leak? If the memory management in Poser is done by reference counting, then memory accesses in the code of SomeFunc() would also be subject to the same reference counting. Hence, if SomeFunc() didn't assign fred to some other (non-stack) variable, then the reference count would be 1 when it was called and still 1 when it returned, so Poser could catch the memory leak. Similarly, if SomeFunc() HAD assigned it to some other variable then the reference count would be greater than one, hence Poser could tell that the second assignment in the above code still left one reference to the 100 bytes and was hence not a leak. As I say, I have no idea what scheme Poser uses to detect leaks, but this kind of approach can certainly do it.

While I'm waiting for a response from them, I figured it wouldn't hurt to ask if anyone here has interfaced to it.

NetLib Programming
Further to my previous question ... Taking a look at sys_socket.h, it seems to define a heap of macros that turn standard BSD style socket library calls into the appropriate equivalent NetLib calls. Palm presumably went to this amount of effort to allow code to be written and tested on *nix and ported to the Palm with little effort. So, is it considered the right approach to use those macros or the direct NetLib calls. I ask this because the one piece of example code that Palm provide in their code recipes area accesses NetLib directly, which makes me wonder why they would do that.

Re: NetLib.h
Hi Steve, As far as I know, everything you need is included in PalmOS.h. Perhaps those instructions were for an older version of the SDK. Why not just try compiling the sample code and see what happens? Yeah. I eventually just removed the #include and everything compiled OK anyhow, so I'm over that bump. Taking a look at sys_socket.h, it seems to define a heap of macros that turn standard BSD style socket library calls into the appropriate equivalent NetLib calls. That's for the convenience of socket programmers. It gives them a familiar set of APIs. You don't need to use them. I don't. There is no _right_ approach. You can chose either set of functions. Since I've done socket programming on *nix before, it's nice to have those available. But I think I'll probably end up doing as you do, since the calls have extra parameters that could be useful to change to different values from those in the macros at some point. Since you're just getting started with this stuff, you might want to pick up a copy of Palm OS Web Applications. It has one long chapter on NetLib. The rest if mostly about INetLib. Another resource is Palm OS Network Programming Applications. It's alla bout NetLib. I've already asked my boss to order the latter, and I've just sent him an e-mail asking him to get the other one. Unfortunately, they'll take time to arrive. It costs an arm and a leg to get Amazon to ship them by fast courier service (around $40) and I've not seen either of those books in stores here. Presumably they're relatively new? One more question for you ... I was able to get everything to compile and ALMOST link. I linked in libNetSocket.a and that sorted all of the NetLib calls. I have some basic code that just finds the library, opens it in AppStart() and closes it in AppStop(). That's linking OK now, so I guess if it runs without falling in a heap I'll start writing some code to do an actual connection and send/receive some data !! By the way, I realise I'm being a bit of a wimp asking questions on here, but I find it much easier to get into things if I can see a complete working piece of code, rather than just the little snippets they tend to give you in the documentation. Thanks for the help. Harry O. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
Re: NetLib.h
Palm OS Web Applications has been out 4-5 months. The other one is fairly new. OK. Maybe it's worth trying a more technical bookshop for Palm OS Web Applications. Thanks for the info. ... $40 is a _hefty_ tariff for shipping. I agree. I think that cost may cover the shipping of a couple of books, but that's what it cost for a fairly thin O'Reilly paperback a couple of weeks ago. I guess that's just the price I have to pay (well, my company does, anyway) for living in Oz. Unfortunately, there aren't a lot of good NetLib examples out that from what I've seen. Maybe I'll make the code I write while I'm learning available, to make it a little easier for the next person. Was there a question in there? :-) There was originally going to be, but I answered it myself before I sent the mail off; I just forgot to remove the reference :-). What I was having problems with was that the macros all use a *nix style errno variable, but when I linked my program that variable came up as an undefined reference. I just defined one in my own code and the link worked fine. I was just worried because I remember reading stuff about shared libraries having issues with global variables. I figure it's OK, though, since the program runs fine on the emulator. Good luck with your project. Thanks. By the way, you're the person who got me into Palm programming years ago, when you had an article on WorldTime (I think that was what it was called) in the magazine you used to publish.

Re: netLib
OK. I worked out how to do an alert in PilRC, so now I know it's the connect
that's failing. It's ages since I wrote socket code at this level. I've
been spoiled using languages like Java and Ruby where the libraries hide all
these details ... as they should, IMHO.
Anyway, here's the code I've written. The Palm is successfully connecting to
the ISP and I have a PPP session established. So, I assume it's something to
do with some of the paramaters I have here.
In particular, I'm thinking the setup of the address may be wrong. The
machine I'm connecting to doesn't have a real name that the outside world can
see, so I've tried to hard code the IP address and probably screwed it up.
The errno I see after the connect fails is 1476, if that gives anyone a clue.
I'm going to have to work out how to convert that to something meaningful.
As I say, it's a long time since I've done stuff at this level :-(.

Generic TCP/IP Access
I'm designing an application that will talk via TCP/IP in a client/server style. I've done absolutely no TCP/IP stuff on Palm at all, so I'm going to sound pretty clueless initially, so bear with me. In the final version, I plan to use bluetooth to initiate a connection to an ISP via a mobile phone. However, since I don't have access to a bluetooth SDIO card yet, I figure it makes sense to make this work initially via infrared. I assume that the initialisation of the PPP(?) connection needs to be done differently for IR versus bluetooth, but that once the connection is established, the rest of the code will be able to do a connect() call without knowing what the underlying PPP is? Ie, whether I initiate the link via IR or bluetooth, I assume that either I get back some kind of descriptor that I can use to initiate the connect() call or that it's hidden from me altogether and simply doing a connect() will automatically use the current underlying interface? Can someone point me at an example piece of code that initiates a PPP session via IR to a mobile phone? Also, a sample piece of code that uses the Palm OS networking APIs to initiate some kind of simple connection would be great, too. Is there a general place I can do searches for this kind of stuff?
