Hi all,
I have encountered some issues adding a board-specific command to the
board file of a project I have been working on. Specifically, after
adding a U-Boot shell command to my board file, I have been seeing
link-stage failures when attempting to build SPL.
It's hard to tell without having your code, but I think this problem
was already discussed in [1]. However I do not remember how Prabhakar
solved it in the end.
Yes, I ran into this thread while debugging the problem, which
ultimately lead me to my solution. From that same thread [1], Wolfgang

This makes no sense. Commands can only be executed when we have full
U-Boot running (actually even only after relocation). You cannot run
commands in the SPL.

I understand of course why it makes no sense to have command support
in the SPL. However, the crux of this problem is that U-Boot and SPL
both link in the same board object file, so in that sense compile-time
switches wont work. From later in [1], Scott Wood writes:
No that's not correct. For SPL we build the object files into a
different directory "spl/". Please see the below in spl/Makefile
# We want the final binaries in this directory
obj := $(OBJTREE)/spl/
Object files used for U-Boot and SPL are not the same. You can use
compile-time switches and it should work just fine.
