Re: [edk2] EDK2 build using Visual Studio

Hi Liming,

Sorry, I mixed up the things :(

If I try VS2015x86 , I'm getting this error:

Build environment: Windows-post2008Server-6.2.9200
Build start time: 15:54:28, Jun.08 2017

build: : warning: Tool chain [VS2015x86] is not defined


build...

Am I missing anything here?

Thanks.

Re: [edk2] Issue in ConvertHandleIndexToHandle and ConvertHandleToHandleIndex

2017-06-06 Thread GN Keshava

Thanks Jaben.

I expected this answer. :) Definitely I can't do that as of now.

But do you think this would cause mismatch between the handle index that i
get in my application? The handle index I'm getting is differing, even if
the handle value is same.

And, could you suggest any other ways to fix this, other than embedding my
app into the shell?

Or do you suggest my temporary workaround , in which I'm embedding my own
sermode functionality inside my application ? The functionality is working
and I'm able to use com port. But it's annoying to have different
information in app than a shell command! :(

Thanks again.

Hi Jaben,

Thanks for the reply.


I understand that the sermode command is in shell, and it's sharing
information through libraries.


Can you tell me more about the library requirement of module to be linked
into shell? How i can do this?


Thanks again.

[edk2] Issue in ConvertHandleIndexToHandle and ConvertHandleToHandleIndex

2017-06-06 Thread GN Keshava

Hi,

Thanks all for your kind help.

I'm doing few operations using serial port. So, I've done a small serial
driver by referring FTDI code, and I'm accessing this using serialIO from
my application. and it was working fine with older EFI shell.

Now I'm using the latest UEFI shell.
Now It's working fine for first time. Then if i do any removal and connect
of serial port, there is a mismatch in "Handle index" value between the one
i get in my application, and the one i get in "sermode" command.

I'm using the same code as sermode code, but still, for the same Handle
value, the handleIndex value is deferring.

Whether ConvertHandleIndexToHandle and ConvertHandleToHandleIndex functions
are giving issue? What could be the reason?

Thanks again.

Re: [edk2] Unmount and mount a mass storage from shell

2017-05-30 Thread GN Keshava

Hi Jaben,

Thanks a lot for your input.

As I have mentioned in previous mail, I'm facing an issue now, that, If I
reconnect my client device, the mass storage is not able to mount again
automatically.
Here is few more details. Expecting some help on this :

I connect the the client device to UEFI host. I get the mass storage
successfully. (device is listed as Mass storage in devices command)
The client device also has serial CDC functionality (It is Linux CDC
gadget, which will enumerate as both Mass storage (FAT32) and CDC serial
com port).
To use serial port, I have developed a custom serial driver. I use VID PID
of the device in this custom driver to bind the driver to the device. I
load this driver, and I get serial port (It is listed in sermode command)
Now I refresh the mapping using map -r. Still I get the mass storage of
device, and I'm able to access it correctly.
Now I disconnect the client from host (UEFI) by unplugging the device.
When I connect the device again, I'm not able to get Mass storage if i run
map -r. But serial port will start to work fine again.

If I run devices command, it is not shown as mass storage. but as linux
gadget.
Now if I use disconnect command, and followed by connect command to this
device with mass storage driver, I'm able to mount the mass storage and use
it.
The issue is present if I load my serial driver, which uses device's VID
PID. If I unload this driver and do the unplug-plug, I'm able to get mass
storage automatically..

What could be the issue? Is there any way to solve this?

(sorry for long post, it's difficult to explain otherwise)

Thanks again.

Keshava

Re: [edk2] Unmount and mount a mass storage from shell

2017-05-26 Thread GN Keshava

Hi Jaben, Thanks a lot for input. My necessity for unmount-mount is that,
the USB client is a Linux storage gadget, which needs to be remounted to
get the updated/new files created by Linux. Anyhow, now I'm doing this
programmatically by copying mount command code from older shell. :)

One more issue is that, after Linux updates some file (on client side,
Linux will mount the same partition, save some file, and then umount the
partition. Then if i remount the partition on Host side, when host is
windows, i will get updated files) I will manually remove and connect the
cable (MS device), UEFI is not able to detect the MS itself. (This issue
observed, regardless of remount. This issue is not there on windows 10
host).
Can you give some pointers on this?

Thanks a lot, Jaben.

Keshava

[edk2] Unmount and mount a mass storage from shell

2017-05-25 Thread GN Keshava

How can I unmount and mount a mass storage fs from UEFI shell?

In older EFI shells, I can do with "mount" command. But it just does
"mapping" in newer shell. It doesn't actually remounting the device.

Please help.

[edk2] Strange issue in USB mass storage device

2017-05-22 Thread GN Keshava

Hi all,

I'm testing a USB mass storage device (A linux CDC gadget, which has serial
and mass storage with FAT32 filesystem) which works fine with Windows.

I'm booting to UEFI shell using another mass storage device (a thumb drive).
My device under test (A linux CDC gadget, which has serial and mass
storage) detects as file system (fsx: ) only if its device path is lesser
than the thumb drive. Thumb drive detects always.
Example:
case 1:
Thumb drive: PCI.../.../USB(*2,0*)/HD(MBR...
Device under test: PCI.../.../USB(*6,2*)

Result: Device under test doesn't mount. But it's just shown as Removable
block device. Even if I use mount command, its not mounted. I cant access
files.

case 2:
Thumb drive: PCI.../.../USB(*6,0*)/HD(MBR...
Device under test: PCI.../.../USB(*2,2*)

Result: Device under test mounts properly as fs2: . I can access files.

Also, it can be noted that thumb drive is shown as "HD(MBR...)" whereas my
DUT does not show this part.

Any pointers would be much appreciated.

Thanks and regards,
Keshava

[edk2] LocateHandle for gEfiShellProtocolGuid is failing in my application

2016-12-20 Thread GN Keshava

Hi,

I'm developing a shell application. A call to LocateHandle for
gEfiShellProtocolGuid is failing with Status 0x0E.

Below is my code. Please let me know what I'm doing wrong.

Status = gBS->LocateHandle(ByProtocol, , NULL,
, Buffer); // Get BufferSize
if (EFI_ERROR(Status))
Print(L"LocateHandle Status 0x%x\n",Status);

Status = gBS->AllocatePool(EfiBootServicesData, BufferSize,
(void**));
if (EFI_ERROR(Status))
Print(L"AllocatePool Status 0x%x\n",Status);

Status = gBS->LocateHandle(ByProtocol, , NULL,
, Buffer);
if (EFI_ERROR(Status))
Print(L"LocateHandle Status 0x%x\n",Status);

All calls failing with Status being 0x0E. Please help me to solve this. Is
there any special requirement for using this protocol?

Thanks.

[edk2] VFAT mounting inconsistency in UEFI

2016-11-24 Thread GN Keshava

Hi,

I'm connecting my Linux device to UEFI-running PC using USB Mass storage.
Linux is enumerated as Mass storage on host (UEFI).

Sometimes, the mass storage is not detecting/mounting on UEFI.
Linux has partitioned it as VFAT. It is always being mounted on
Windows/Linux.

Has anybody tested this?

[edk2] COM port usage in UEFI

2016-10-25 Thread GN Keshava

Hi all,

In my UEFI application, I'm using Serial protocol to access COM port. I'm
able to access COM port successfully.

But I'm confused on how we can get user input regarding which COM port the
user wants to access.

*Example, I have already a Windows application for the same, where user
selects the COM port number he wants to access, such as COM1: , COM30: etc.*

In UEFI, I'm using COM port Handle Index (which user gets/uses in
*sermod *command,
like , *myapp.efi 31F* , where 31F is com port handle index).

Is this best way possible in UEFI? Or is it better to use HANDLE itself? Or
is there any way to get input as COM port number same as Windows app?

Thanks!

[edk2] Format a volume in UEFI (or delete all files)

2016-10-12 Thread GN Keshava

Hi all,

I need to format fs1: (or delete all files and folders in root directory)
from my UEFI application.

I'm able to use file system APIs such as Open, Write or Delete too. But
Delete API needs File (file path) as argument, but what I want is delete
all files (irrespective of file name).

What could be the best method? Is there any API to directly delete all
files? If not, How to go through (Open) all files and delete each?

How I can get each file and folder names in a directory programmatically ?

Thanks.

[edk2] Use fprintf in UEFI

2016-09-29 Thread GN Keshava

Hi,

There is fprintf function in Stdio library. But how to use it? The first
argument is "FILE" type. But I have "EFI_FILE_PROTOCOL* File" which I got
from "EFIOpenFile" function. How to map to "FILE" type?

Sorry if this is silly. A newbie here. Didn't get much idea in internet
search. :)

Thanks.

Hi Laszlo,

Thank you for the answer. It was helpful.

Considering option #1, can you give some more details (a small example or
any reference link would be helpful), how I can use Shell APIs in my C file
(which will compile to my .efi app)?
Considering option #2, How I can find device path programatically from my C
file?

Thanks again for the help. :)

Hi Andrew,

Thanks for the reply.

Can you tell more about (or some links) about the Shell APIs that you have
mentioned? Is it possible to access these from my C code? (not script, its
C code for my .efi app).

Also, can you give more idea about how I can map my volume name to device
path in my C file?

Thanks.

[edk2] How to open a file by it's full path in UEFI

2016-09-27 Thread GN Keshava

Hi all,


I'm trying to open a file from my UEFI application. The path of file is

fs1:/myfolder/myfile.txt

The code :

efiStatus = bs->LocateHandleBuffer(ByProtocol,
   ,
   NULL,
   ,
   );

for (index = 0; index < (int)handleCount; ++ index)
{
EFI_SIMPLE_FILE_SYSTEM_PROTOCOL* fs = NULL;

efiStatus = bs->HandleProtocol(
handles[index],
,
(void**));

EFI_FILE_PROTOCOL* root = NULL;
...
efiStatus = fs->OpenVolume(fs, );

EFI_FILE_PROTOCOL* token = NULL;

efiStatus = root->Open(
root,
,
L"myfolder\\myfile.txt",
EFI_FILE_MODE_READ,
EFI_FILE_READ_ONLY | EFI_FILE_HIDDEN | EFI_FILE_SYSTEM);
}

But using this method, I can only go through all the file system handles
and open each volume and try opening my file.

But I want to give full path to my file and open it in it's volume.

How can I acheive this?
Thanks.

Re: [edk2] UEFI Sample application for read/write serial IO

2016-09-01 Thread GN Keshava

Thanks Michael,

By sample I mean is there any code which uses Serial IO Protocol to
read/write to UART in edk2 package? or any open source code should be fine.

This is just to get an idea how I can use the protocol.

Thanks
Keshava

Hi all,

I want to write UEFI application which reads/writes to serial IO.
Is there a sample UEFI application code available which demonstrates Serial
IO read/write?

Thanks.

Re: [edk2] USB 3.1 Support in UEFI

2016-08-15 Thread GN Keshava

Hello Feng,

Thank you for the reply.

I understood, USB type C displayport alternate mode needs mux switch, and
hence should be supported by silicon vendor.

Whether DisplayPort is supported ? (not usb type c, i just need to use
DisplayPort (instead of vga display, i want to use displayport and
supported monitor and cable)).

Thanks again,
Keshava

Hi all,

I heard that UEFI supports USB3.0. Please confirm.
Also let me know if *USB3.1 is supported in UEFI?*

Als, It would be helpful if anybody please let me know
DisplayPort or USB type C is supported in UEFI.

Thanks Feng. Even I felt the same way. Just wanted to know if there is any
other such,  more nearer driver available in UEFI for USB to serial or USB
CDC driver source code? Please confirm... If not, I will go with ftdi
driver.

Thanks.

Re: [edk2] UEFI driver for USB CDC ACM Serial device

2016-07-06 Thread GN Keshava

Hi Feng,

Thank you for your time.

Yes, the PC is connected to board using USB cable. The board is running on
Linux, and it is detected as CDC serial on PC.

On Linux Host machine, the device works straightaway as ttyACM0:

Would you suggest any reference driver in UEFI that I can refer for
developing a driver for my device? Any good starting point?

Thanks.
With regards,
Keshava GN

[edk2] UEFI driver for USB CDC ACM Serial device

2016-07-05 Thread GN Keshava

Hi all,

I'm new to UEFI development.
So far, I have learnt about UEFI shell, build procedure and application
basics.

My task is to communicate to a custom board from UEFI using uefi app
through a USB serial cable from the PC.

Currently, the PC is booted to UEFI shell and connected the board through
serial cable and I type "devices" command, I see that the board is listed as

"344 : CDC Abstract Control Model (CDC)"
and
"345: CDC ACM Data"

Please help me to understand how I can proceed? and what works I need to do
in order to detect my board as Serial port? Is there any driver available
for this? If I need to develop the driver, please help me on what would be
the starting point?

Thanks.
With regards.
