Hi everyone, I am developing bootloader based on MC9S08SG32. I modified my prm file and source code followed AN4440. After downloading my source code,the pc jumped to main app directyly, not the boot code. Could anyone give me some help? thanks!

Hi

 

This is an old AN4440, are you using code warrior classic? 

 

I download the code for this application note but is in codewarrior 6.3, now I do not have it.

Maybe the AN2295 can help you to check the bootloader process
