I am compiling the linux-2.6.33.tar.bz2 kernel that I downloaded from this site: http://www.at91.com/linux4sam/bin/view/ ... inuxKernel

I first applied the patch 2.6.33-at91.patch.gz and then compiled with the following commands:

make menuconfig ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

The second command has given me this error:

drivers/input/touchscreen/eeti_ts.c: In function 'eeti_ts_irq_active':
drivers/input/touchscreen/eeti_ts.c:64:2: error: implicit declaration of function 'irq_to_gpio'
make[3]: *** [drivers/input/touchscreen/eeti_ts.o] Error 1
make[2]: *** [drivers/input/touchscreen] Error 2
make[1]: *** [drivers/input] Error 2
make: *** [drivers] Error 2

How to solve this? I don't want to go in a modify things - I'm just trying to compile a provided kernel as-is.

Thanks.

Did you copy the relevant board config file from arch/arm/configs to .config before doing
make menuconfig ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
(cp arch/arm/configs/at91sam9g20ek_defconfig .config)

It should compile with a default board configuration, if you do not select any aditional features. Which board are you trying to compile for?

No, I didn't. Thanks, that appears to be it. By the way, thanks for writing out the actual command to do the copy. It made it much easier than me trying to figure out where the file was, etc.

I am compiling for the at91sam9g20-ek board.

So after the make, I saw two files in arch/arm/boot:

Image (3218976 bytes)
zImage (1613300 bytes)

I replaced the pre-compiled binary that was working with both Image and zImage and when I booted up the board, this is what I saw in HyperTerminal:


NAND read: device 0 offset 0xa0000, size 0x200000
2097152 bytes read: OK
Wrong Image Format for bootm command
ERROR: can't get kernel image!
U-Boot>


So neither of these images is correct. What do I do next?
