Yes. Debugging a bit further i enabled the hard fault processor
exception catch in
RVD. On doing this i notice that when running commands (like 'ls' or
'date') on console
the processor hard faults. The HFSR shows "0x40000000" while BFSR
reads "0x04" indicating an imprecise data access fault. Other U/MMFSR are 0x0.

I am wondering why an imprecise data access fault could happen at this stage ?
