U-Boot for Nios2 on DE2-115 Board with MMC/SPI support

Jan

I am trying to build Uboot for Nios2 also. No luck but I have learned

a few things.

Uboot configuration for nios2 has changed significantly.

The Alter-Wiki is way out of date. It didn't work for me either.

There is a special git repo for nios2 at git://git.denx.de/u-boot-nios.git.

Uboot is moving to Kconfig and Make files - i.e. "boards.cfg" is deprecated.

This explains why I did not find "boards.cfg" after git cloning.

I tried the following on Linux bash.

> git clone git://git.denx.de/u-boot-nios.git

> cd u-boot-nios/

> make menuconfig

These proceeding steps complete with no visible errors or warnings. Make menuconfig

has a lot of configuration options - it may support what you are trying to do.

You can also run > make config and you'll get many, many configuration choices.

Then I run

> make all

This step fails for me with the following error

LD arch/nios2/cpu/built-in.o

/bin/sh: nios2-elf-ld.bfd: command not found

scripts/Makefile.build:354: recipe for target 'arch/nios2/cpu/built-in.o' failed

make[1]: *** [arch/nios2/cpu/built-in.o] Error 127

Makefile:1037: recipe for target 'arch/nios2/cpu' failed

make: *** [arch/nios2/cpu] Error 2

I confirmed that both 'nios2-elf-gcc' and 'nios2-elf-ld' are in the path and are executable.

And since I have been running Nios2 successfully on Linux this should indicate my 'nios2-elf-gcc' and 'nios2-elf-ld'

should be OK. It appears the compile completed but the nios2 linker is not found.

Just a heads-up that have been some big changes for the steps required for building Uboot for nios2.

Sorry, but I have not found any up-to-date build instructions either.
