Thanks for your help.

I had tried passing the path explicitly but then it hit an error that
it could not find files in asm . So I concluded something must have
fundementally got broken and it should find the cause rather than
messing with bandaid solutions.

Last time I compliled my adc prog I just called make adc_logger , no
one has touched either the source or the Makefile since.

It seems related to the kernel change I put into the board.

Correct me if I'm wrong but I should not need to explicitly add the
kernel include and asm paths with -I , so where do they get picked up?

That should put me on the trail of what is broken.

Thanks again.
