Unable to jump from boot loader to application when external clock using

[saileshpandey]

Hello,

I am making very first time boot loader for MC56F8257.

I succeed in making simple boot loader which can download application Via CAN communication.

for development I was using simple LED program and now my boot is able to download Application and after checking

checksum able to jump to application ( Application entry address is hardcode) . And application is running properly even in

new power cycle( power OFF then power ON).

But when I am trying downloading original application then I am getting problem in jumping to application(after executing JUMP instruction its hanging or lost some where).

After investigating I came to know that, when ever I am using External Clock in application then I am getting problem while jumping to application.

I tried resetting COP timeout also in application starting but then also nothing happen after executing JUMP instruction its hanging or lost some where.

I know its some problem related to peripherals.

Please let me know if solution is there or anything wrong I am doing.

Thanks

Problem got resolve.

mainly we have to change vector base address before starting application using INTC_VBA.

thanks
