There might be some accesses to flash, but LED is too quick for human eye.
After the accesses the CPU could freeze. It looks like you have burned invalid
data into the flash. Please try to connect an oscilloscope to the CPU and watch
if there is really no activity on the bus. If there is no activity, then your
CPU (or board) is broken.  If there is any activity on the flash bus, then the
software is invalid.
