Make the initial setting of this variable a Kconfig configuration option. The reason there can be excess space is that the allocator only allocates in power-of-2 size chunks, but mmap()'s can be made in sizes that aren't a power of 2. There are two alternatives: (1) Keep the excess as dead space. The dead space then remains unused for the lifetime of the mapping. Mappings of shared objects such as libc, ld.so or busybox's text segment may retain their dead space forever. (2) Return the excess to the allocator. This means that the dead space is limited to less than a page per mapping, but it means that for a transient process, there's more chance of fragmentation as the excess space may be reused fairly quickly. During the boot process, a lot of transient processes are created, and this can cause a lot of fragmentation as the pagecache and various slabs grow greatly during this time. By turning off the trimming of excess space during boot and disabling batching of frees, Coldfire can manage to boot. A better way of doing things might be to have /sbin/init turn this option off. By that point libc, ld.so and init - which are all long-duration processes - have all been loaded and trimmed.

Re: [uClinux-dev] ltib vs uclinux-dist
Philippe, These are all good questions. Here at the office we make use of both Freescale's LTIB release and the uClinux-dist release. When Freescale releases a new part and matching evaluation board they will release it with a tool chain (from CodeSourcery) and an LTIB that is aware of the new CPU and Board. Kernel == Typically the LTIB released kernels for their MMU-less processors are not the most current and may be several version behind the main Linux tree and Greg's uClinux kernel releases. Given the lag in kernel version those that need to use the most recent CPU's may need to use the older LTIB released kernel as Freescales releases are not in sync with Greg uClinux nor Linus's kernel trees. Once forward porting of the CPU and Board support from LTIB's kernel release to the uClinux and Linux trees, it become easier to make use of the uClinux kernel than the older kernel from LTIB. This is also true of some driver support between kernels as well. User Applications = The LTIB released user applications are a collection of public packaged user apps that are well used on MMU-full processors ARM/PowerPC etc. In many cases these applications are full featured (read big) and not always optimized to reduce their size and functionality typically needed for embedded use. While you can modify the source, the LTIB frame work takes a far bit to get up to speed with. If you have the opportunity you can contact your Freescale reps and they can point you to a few online resources (Freescale's Virtual FTF is one) that walk you through how to use LTIB to build and deploy images for their evaluation boards. Where as the uClinux-dist has a collection of applications that have for the most part been reduced in functionality and size to fit better on an embedded device. That said their many be a few applications that may be kernel version and C Library specific in their functionality. This is in part as the uClinux-dist had attempted to allow support to earlier 2.0, 2.4 and 2.6 kernels. Tool Chains and Libraries = The C library and build tools such as uClibc, glibc, GCC, etc are all available in source and can be recompiled to enable and disable features as well as allow you to alter install paths. At the office we have used the Freescale release toolchains on both LTIB and the uClinux-dist wish success. That said we do eventually end up changing the configuration, install path etc to keep the compiler, C library and Kernel in sync.

Hello,
I am working in a controller using the motorola coldfire 5282 into the
uCevolution test board from Arcturus. In the last days, I downloaded the
uClinux-dist-2008-FEB-05-r0-release distribution from arcturus site.
It's working with the kernel 2.6, and I understand that this
distribution have a better support for i2c communication. I have been
tried to implement the i2c but I don't know how to do this.
I have configure Device Drivers
I2C Support
m I2C Support
m I2C Device Interface
I2C Hardware bus support ---
m MCF Coldfire
Then I read from documentation inside the distribution
linux2.6/Documentation/i2c/dev-interfaceto use this protocol is
necessary only do this:
So let's say you want to access an i2c adapter from a C program. The
first thing to do is #include linux/i2c-dev.h. Please note that
there are two files named i2c-dev.h out there, one is distributed
with the Linux kernel and is meant to be included from kernel
driver code, the other one is distributed with lm_sensors and is
meant to be included from user-space programs. You obviously want
the second one here.
Now, you have to decide which adapter you want to access. You should
inspect /sys/class/i2c-dev/ to decide this. Adapter numbers are assigned
somewhat dynamically, so you can not even assume /dev/i2c-0 is the
first adapter.
Next thing, open the device file, as follows:
int file;
int adapter_nr = 2; /* probably dynamically determined */
char filename[20];
sprintf(filename,/dev/i2c-%d,adapter_nr);
if ((file = open(filename,O_RDWR)) 0) {
/* ERROR HANDLING; you can check errno to see what went wrong */
exit(1);
}
When you have opened the device, you must specify with what device
address you want to communicate:
int addr = 0x40; /* The I2C address */
if (ioctl(file,I2C_SLAVE,addr) 0) {
/* ERROR HANDLING; you can check errno to see what went wrong */
exit(1);
}
but this does not work, I need more documentation and if is possible a
example that can help me to make my work possible.
I have seen that can be load a module for i2c in the mcf called
i2c-mcf.c i load the module using insmod i2c-mcf.ko, but my question is
how i can use the function in that the module have, or how i can use
the driver I am confuse.

Re: [uClinux-dev] uCLinux web site down?
Claude wrote: Hi to uClinux web masters. Howdy Claude, For some months ago I have noticed that there are periods of time in which accessing to uClinux web site is slow and often impossible. Is there any problem with the uClinux site server? Well, maybe the reason is that, since uClinux is a fantastic creation, there are more and more developers that are discovering it and, thus, overloading the website to download the code. In that case, if there is any developer that has taken profit of uClinux and owns a web hosting business, please donate some servers to uClinux.org!!! :-) Donation to increase bandwidth for the project are always welcome. We have paid for additional bandwidth with iPower in the past to off load some uClinux-dist traffic but iPower shut down all large file transfers as our bandwidth use was being reported as impacting other users of there webservers. That was a sad day! Turns out several users in China and in Europe had been using aggressive transfer methods and resulted in a denial of service for iPower perhaps? I am not sure as iPower was not helpful in resolving the issue. Their solution was to just disable our account. Again .. very sad. To those who are already donating time, servers and band width: our thanks goes to Analog Devices, Arcturus Networks Inc. and Secure Computing (SnapGear). So if anyone knows of others who are willing to provide addition bandwidth for the large file transfers please drop me an email [EMAIL PROTECTED] or give me a call at (416) 621 0125 Cheers, Michael [EMAIL PROTECTED] Cheers.

Re: [uClinux-dev] irc on freenode #uC-Linux
David McCullough wrote: Jivin rwarner lays it down ... Markus Franke wrote: Zitat von rwarner [EMAIL PROTECTED]: I prefer #uclinux as this is much more intuitive than the hyphenated version. No one uses either so it's really a moot issue. Maybe a forum type setup with multiple areas to separate out some of the discussions. I think the non-usage is due to the highly distributed nature of where we are all located. ML or forum structure fits this best. Problem with a ML is you get every single mail that may or may not pertain to something you are working on with respect to the uclinux dist and or kernel. Note other ML try to setup multiple ML, but this becomes unwieldy with any break down into upper level subject matter(s). Some example forum topics would be eg 'NoMMU vs MMU', 'configuration' and 'patches' to name a few My vote for #uclinux. I would also consider asking the guys at Arcturus if they could add the IRC channel info to the lists auto added footer somehow. I think some of the reason none of the IRC's have picked up is because no one knows about them, and if they do a search they are likely to find several and not know which one would work best for them. I think including it in the footer of all uClinux-dev mailings could help people remember/locate it (I know it's extra noise in the mail but it wouldn't bother me though), Will do -- Michael Cheers, Davidm ___ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev

Re: [uClinux-dev] HTML and this list
Phil et al We have been filtering out and converting HTML to plain text for a few years now. But the conversion did not properly catch all the tags in the conversion. So I am on the side of educating posters to use plain text and letting mailman do its best to convert for those that forget from time to time. -- Michael Durrant Phil Wilshire wrote: Michael Durrant wrote: Any objections from the list? -- Michael Durrant Gregg Levine wrote: Hello!

Re: [uClinux-dev] uClinux-dist unavailable
David McCullough wrote: Jivin Claudi Jr lays it down ... Hi, Current link to uClinux-dist-20070130 has been broken at least for a week, so far. I cannot download it from www.uclinux.org/ports/coldfire page. There is a test distro but I want the latest complete one, which is 20070130 and its patches. Actually I downloaded the test version but there's no way to run make menuconfig, so I imagine the next full distro will be fully functional. Till then, I'd like to work with the 20070130 distro. Does anybody know if some site update is being done these days? When will there be a full distribution available again? Yes the bulk web server was migrated recently to a new machine and this just finished the migration. -- Michael Durrant deleted bits Cheers, Davidm ___ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev

Re: [uClinux-dev] Appropriated Starter Kit to run uCLinux
Renato, Do you have any specific features that you are looking for in the target hardware? Specifically if you would like to learn more about uClinux for a project you have in mind, you may wish to acquire a board with the features you need. Freescale (ColdFire) and Analog Devices (BlackFin) offer hardware that both companies are supporting. Some hardware is better supported by the community in the 2.4.x kernel as it has been available for years. Where as newer processors are being released with only 2.6.x support. Arcturus Network (where I work) also sells a few different m68k and ColdFire modules. Several people on the list use these modules for development and embedded in shipping products. If you do a search through this lists archive you will see them referred to as uCsimm or uCdimm(s). Here is a web link to our website where we list the available products and development kits. http://www.arcturusnetworks.com/products Regards, Michael Durrant Renato Pedevilla wrote: Hi!
