Hello! I would like to compile U-Boot with custom configuration. I downloaded source from the master git repository (http://git.denx.de/?p=u-boot.git;a=summary). I am trying to compile using following commands: $ cd u-boot/ $ make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnu- at91sam9g20ek_nandflash_config $ make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnu- all
seems good to me.
It goes on for a while, and then I get the error: crt0.S: Assembler messages: crt0.S:70: Error: register expected, not '#(184)' -- `sub sp,#(184)'
make[1]: *** [crt0.o] Error 1 make[1]: Leaving directory `/root/u-boot/arch/arm/lib' make: *** [arch/arm/lib/built-in.o] Error 2
crt0.S:70 subtracts the GD_SIZE from current stack pointer. The code written seems to miss the Rn according to [1]. Could you please test to change it from to: 'sub sp, sp, #GD_SIZE'?
I wonder why my toolchain ignore this. It obviously take Rd == Rn when Rn is missing.
Best regards
