All this starts from the CAN init code crashing (SAMA5D27) when it makes any
call to print debug messages. Printf itself is fine.
These kinds of crashes are often due to stack overrun. It might be
worth increasing the stack size of the task that calls CAN init.
Has anyone got NuttX to successfully compile, and allow debug, under either
MAC or Windows. At all? Ever?
This SAMA5Dx support was developed on Windows under Cygwin using the ARM
