Hi, Which 68HC11 have you ? 68HC811E2 ? In the 68HC11 family, the internal ressources (RAM, registers, EEPROM,..) are "more important" than external ressources. If you want boot on a external memory, you need external memory for the vectors ($ffd6 $ffff). So, if it's a 68HC811E2, you have to move the internal EEPROM (standard = $F800-$ffff). In your code, you need :
org $fffe fdb $8000 (if the start of your code is $8000)
org $8000 ... ... Regards,
Yvan
