I am trying to implement a bootloader for S12P. I downloaded the AN3275SW which claims to work for all S12 microcontrollers. But when I flash my microcontroller with the code provided, it hangs in the startup file itself. I modified the code to make it deliberately jump to main. It does so but then it hangs as soon as it comes across any function call. Can you tell me what could be wrong? Are there any software updates for AN3275 or are there any changes I need to do in the Standard Settings in CodeWarrior?
