cannot open output file u-boot: Is a directory

Altera_Forum · ‎11-25-2011

in u-boot dir, I put my_nios2.h in include/configs/, put my_nios2_fpga.h in board/altera/nios2-generic/. Then add an entry my_nios2 to the NIOS2_GENERIC list in Makefile.

make my_nios2_config

make

then...

what's wrong ? Thax!

It looks like it's trying to write the compiled project in a file called u-boot but there is already a folder with that name in the destination folder. Try to move or rename that folder, or to change the name of the generated file
