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 ? --RK
