while trying to build happens that _lock_t and relative functions are not accessible from drivers/iomem.c

Hi. While trying to build the SDK happens that lib/drivers/iomem.c makes use of _lock_t type and its relative functions, however the build fails since those functions and type are not accessible from there.

I am facing the same issue. Is there any solution yet?

You are most likely on the develop branch. Try 0.5.6 instead.

$ git checkout 0.5.6
