Jumping to App code

yalamandadosaky — Thu, 29 Jun 2017 05:39:00 GMT

Hi , I am working on boot loader project for MPC5777M board, currently I am able to flash the application code(the same (Z7_0.elf) file converted to .srec and then flashed at flash blocks),after that I am trying to jump to the flashed location , but it is not going there and giving exception IVOR4 " no source available".

I want to some clarity on what are things to be taken care after flashing a file and make it run successfully when we jump to the flash location, like any modifications required for the .srec file .

Hello,

this topic is not easy enough to tell you, what is wrong with your project. I recommend you to read application note from Lukas Zadrapa which describes, how to create bootloader and to load it into the microcontroller.
