Hi, I'm newbee. What wrong with chip? I have mc9s12c64 chip. And PODEX BDM. I sucsesfuly burned and erased some code . Also have tryed to build some "hello world projects" which worked OK. After last bunning uc didn't respond to bdm. I tryed different frequencies in hcs12mem and figured out chip respond to bdm on twice lower osc frecuency then it realy is. When I try to unsecure chip i get this:error: FLASH access error (ACCERR bit set)and then this: error: FLASH protection violation (PVIOL bit set) Is it sill possible to erase chip.
