Dear Waibel Georg,

MPC5200B base board. Erasing / Programming works fine as long as the flash
sectors are not protected (via PPB bit). On a protected sector the erase command
fails (what makes sense). I thought I can use the unlock command to unprotect
the sectors, but this command seems not to work:
