Hi,
While playing with armv7m, I found two little bugs:
- When there is an alias @0x00000000 to a flash memory the cpu state isn't
reset correctly which leads later to an exception as ARM instruction-set is
used. Presumably this bug might be present with the netduino2 board.
- If the developer omits to set system_clock_rate we later go in a livelock
when systick is triggered. Better aborting before to avoid the pain chasing
the livelock.
Thanks,
Fred
