CAN can not send out data.

[100asong]

Hi,Dear All

        I meet an strange thing:CAN can not send out data when I operate the flash.But if I don't operate the flash,I means I disable the flash code related, CAN can send normally out data .MCU is mc9s12xep100.

       When my CPU is running, CAN code is in flash zero,Flash code is in ram. The question is from here?

       Please give me support.Thanks!!!

What does "operate the flash" mean? Are you writing to flash memory cells? Program memory flash or "data flash"?

If you are writing to program memory, no code in the flash bank being written to can be executed at the same time.
