Illegal BP

[abhijithshankarenn]

Hi NXP Team,
   I am using S12GA64 µC in my project.
   While I am trying to flash, the program is going to ILLEGAL_BP.
    Suppose if I am calling MCU_init just before calling the flash program driver command, the program is NOT going to illegal BP.
   Kindly let me know any insights or suggestions to solve this problem.

Hello Abhijith Shankar,

I understand that the issue is solved if you call the MCU_init() function.

So, what does the function do?

I can only guess, but since you mentioned a flash program command, do you set FDIV correctly?

This issue is solved when you disabling the interrupt before writing the flash memory.
And re-enabling the interrupt as soon as the write is over. 
 
TE register needs to be made 0 before any flash operations are carried out. And re-enabled after the flash operation is done
