i'm using EVB9S12XEP100 which contains PC9S12XEP100 with mask set 0M48H.
i have a problem with erasing/programming the flash blocks.
in True-Time when i load an abs file i have the following messeg " attempt to run or to stepan application while flash modules are selected do you want to unselect allmodules and run/step" i choose yes or no and found no difference.
the problem is: when i open the flash window and trying to erase the ALL_PPAGES it always fails. also when i try to load an abs file it always fails at the verification.
in the flash window i find that ALL_PPAGES starts at 00C0,8000 and ends at 00FF,BFFF  !!
i think this is not implemented in my device (in the datasheet i found that FLASH range ends at 7F,FFFF)
True-Time chooses mcu02D3.fpp by default as a configuration file for flashing.
summary: i think that i cannot program or erase flash blocks starts from adress FFFF.

kindly help.
