uClinux without Flash (again)

I decided to give uClinux a try on my custom board, but I only have an SD card slot, no CFI. When reading the install guide for uClinux, and when trying it, it won't let me build a kernel project...

now I develop linux kernel in linux(redhat 9.0)

1. copy /bin/nios2-elf-.... to pc from CD of nios2linux

2. set PATH

3. make hwselect ; make menuconfig ; make (like you stated out)

the .config is much like you post in this thread.

here is linux log
