So you are doing LED debugging? That's brave ;)

That's crazy. It is the method I used to bring this board into the linux kernel, and I still have my good morse over a LED code, with which I debugged early initcalls in the kernel. But that's very very tedious :)

Ah, this is the wheel I was speaking of :)
I had missed the "CONFIG_DEFAULT_ENVIRONMENT_GENERIC" part, and I didn't see anything in the linker (as it actually is in a generated .h file ...).

Great, thanks for the info, I just recompiled, and a hexdump shows my environment within barbox.bin.

Cheers.
