Guys
I have spent US$ 750,00 for a Development kit which I have been struggling for 2 weeks without been able to load a linux kernel generated by me in it. I have try several versions from 2.6.30 to 2.6.35 with no success. Can anybody help me ?

This is a partial list of the kernel generation:

Kernel: arch/arm/boot/Image is ready

Here is the loading in the board:

Perhaps this is a problem with the Machine Type number. uBoot passes this number to the kernel, and the kernel checks if the number provided by uBoot matches its own machine type number. If they don't match, the kernel doesn't boot.

The machine type for the 9M10/9G45 is:

MACH_TYPE_AT91SAM9M10G45EK 1830

Please see linux-2.6.xx/arch/arm/tools/mach-types
and uboot/include/asm/mach-types.h

To solve this, you can, for example, recompile uboot with
make at91sam9m10g45ek_nandflash_config
make

and configure the kernel (make menuconfig) with the correct "System Type" options.

Thank you very much for your answer.

Uboot can load and run thedemo Linux code for the AT91SAM9M10-G45_EK plataform. I have tried to recomplie the kernel with the MACH_TYPE_AT91SAM9M10G45EK set and I got the following compile error:

CC arch/arm/mach-at91/hx170dec.o
arch/arm/mach-at91/hx170dec.c: In function 'hx170dec_isr':
arch/arm/mach-at91/hx170dec.c:601: error: 'SIGIO' undeclared (first use in this function)
arch/arm/mach-at91/hx170dec.c:601: error: (Each undeclared identifier is reported only once
arch/arm/mach-at91/hx170dec.c:601: error: for each function it appears in.)
arch/arm/mach-at91/hx170dec.c:601: error: 'POLL_IN' undeclared (first use in this function)
make[1]: *** [arch/arm/mach-at91/hx170dec.o] Error 1
make: *** [arch/arm/mach-at91] Error 2

Any clue?

Has anybody managed to compile and load a kernel in the AT91SAM9M10-G45_EK platform ? Is there any official support for this platform ? I am almost 15 days trying to compile and load a kernel to it. I have gone through all available "guide" to use it and I either cannot compile or Uboot cannot the generated module. I am just about to move my project to Samsung processor.

Probably not on the forum, the typical route to seek support would be from your local ATMEL representative and/or FAE.

I don't have a G45, but have not had any problems using buildroot on SuSE to build kernels for 9260's and 9G20's. From your message to date I can't ascertain what you build environment is.

I'll try to build a 2.3.60 from the at91sam9m10g45ek_defconfig on the FTP site.

Thanks for your help.
I have tried to do everything from the beginning and I sitll cannot generate the kernel. Please, tell me what I am doing wrong.

The result is :

/home/CameraKit/linux-2.6.35/scripts/gen_initramfs_list.sh: Cannot open 'root'

After remove 'root' from the CONFIG_INITRAMFS parameter I could finally compile the 2.6.35 kernel.

Wrong Image Format for bootm command
ERROR: can't get kernel image!

Can anybody help me. I bought this development board one month ago to supposely speed up time to market and I couldn still compile and run a sungle kerne,

I doubt that you have any SDRAM at 0x200000.

Boot the demo kernel for an example of where to load the kernel and what to expect. Or look at your first post in this thread for a more reasonable load address.

Regards

Thanks blue_z!
You were corrected. I have entered the wrong address. Now I can load and run the generated kernel.
I was so upset with this development kit that I could not see this silly mistake.
Many thanks
