If you find another way to do this overlay yet end up producing a different binary, I'll be interested in the result, but I honestly don't think you will find any.
[sp] I am trying on this. Getting back to linker scripts after many years. But assuming that there is no way; I am still looking for an explanation on:
1) why the current metod produces different errors across different toolchain versions.
Good question. I know this linker file is exactly the same as for arm926ejs, and I don't get the error with edminiv2 which is arm926ejs based; so it's not only different toolchains, it is also different boards or even different build environments.
2) How does presence of one variable alone breaks the build?
Good question again.
At least, compiler doesn't complain. Even moving it out of .bss by explicit initialization doesn't help. BTW, I verified that it is not used anywhere till end of board_init_f() - didn't go further. Should I?
For the moment we should focus on what happens when we use the current .lds -- it causes a linker error, right? Once we get this sorted out, we'll see if the build actually runs.
Can yo help me on these?
As for the linker error, I am sorry I got a bit lost: I know which toolchains you tried (2010q1 and 2009q1) but not exactly which codebase you build (is it v2010.12-rc2 ? master ? specific patches?) or which board you build. Please refresh me on this, so that I can reproduce the issue locally (I've got 2010q1 already installed).
