Hmm, I take this as a refusal to help and a refusal to acquire new information. For me
this is quite a basic problem, perhaps with my understanding, but meanwhile I guess not
with my understanding, but with U-Boot itself. I'm not really looking for a workaround.
The workaround for me, would be to change the common code and do another round of
testing on all affected systems (which by the way is also needed with your suggestion).
I was looking for information, understanding and a reason, why the way I had chosen
failed. And once again, your suggestion to initialize a pointer in my project dependent
code, absolutely ignores the fact, that the array is declared in common code as:
extern const char walter;
Perhaps you don't see a difference to the following notation, which I had to use in my
project dependent code:
extern const char *walter;
But there is one, even if you refuse to recognize. Feel free to ask, if you'd like to
I also wonder, whether the issue with the relocation of statically initialized pointers
