Dear Waibel Georg,

CCing Wolfgang, he's the expert on both IMO.

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:
