Thomas,
All,

Sorry for late answer, I was on holiday...

Are the remaining issues toolchain-realted?
If so, what are they?

Well, as you'll see soon enough, "bare-metal" in crosstool-NG is really
that: "bare-metal". It's only a C/C++ compiler, no more. You program will
have to provide all that is needed to speak to the system, provide common
/functions/ (memory management, etc...) and /objects/ (semaphores, shared
memory, etc...) if it needs them.

Really, bare-metal, no more.

I used such a bare-metal compiler to build a bootloader, which has all
it needs to build.

Regards,
Yann E. MORIN.
