ILLEGAL_BP

[ZzzzzZzzzz]

Hi,

I use MC9S12G128 for programming, there are two programs, APP and BOOT,They all work fine on their own, when merged, BOOT jumps to APP, it will prompt ILLEGAL_BP.I use RTI and CAN receive interrupt, adc sampling and polling to execute, when I comment out the adc function, Can jump normally, this is why, please help to answer!

Please make sure the IVBR is relocated to the correct vector table of the APP.
