Heh. Wait. So far we don't even deal with things like caches ;-)

This actually makes little sense to me. Avoiding this here will just
make the problem pop up somewhare else later.

Not really. The thing is that I don't see any such problem:

$ ./MAKEALL da830evm

Boards compiled: 1

Seems to be a toolchain issue. [ELDK rulez :-)]


Ah. With "USE_PRIVATE_LIBGCC=yes" I see this one:

	undefined reference to `__aeabi_uldivmod'

Note that this is __aeabi_uldivmod, not __udivdi3.


Which version of compiler / which tool chain are you using?

Best regards,

Wolfgang Denk
