porting u-boot to nios2

Altera_Forum · ‎12-24-2010

Hi all,

I'm very new to this embedded world especially to u-boot.I want to port the u-boot to nios2 processor for the DK1S10 board.

I tried it for the source code which i downloaded from sourceforge.net.(u-boot-1.3.4) .But i got list of errors.

nios-elf-gcc -g -Os -D__KERNEL__ -DTEXT_BASE=0x018c0000 -I/home/pranesh/waters/u-boot-1.3.4/include -fno-builtin -ffreestanding -nostdinc -isystem /lib/gcc/nios2-elf/3.4.6/include -pipe -DCONFIG_NIOS -D__NIOS__ -Wall -Wstrict-prototypes -c -o stubs.o stubs.c

So I got suggestion to download the code from link psyent.com/download .But it does not contain the DK1S10.h file .So Please help. How should i proceed now ??

nios asm source shouldn't contain %g0 (or similar) at all.

At a guess the C source contains 'asm' statements for some other instruction set, or, just possibly, your nios-elf-gcc is somehow generating code for a different cpu!

Not sure what code you have, might be sparc64!
