Hi everyone,please forgive me for my poor English.

In MC9S08DZ60, I wrote a bootloader in case to upgrade my application, now I met a problem. In my bootloader, if no upgrade signal received from CAN-BUS, then jump to application. When jumpped to application, some functions could not execute, e.g. I send  commands via CAN-BUS to application, some commands have right response, but others no.

I don't understand why?  If only program application into flash, it running normally. 

Could anybody help me?

Best Regards!
