Changing SP and PC values in tm4c123gh6pm

Hello Reshma,

The SP and PC values can be modified using the  CallApplication(uint_fast32_t ui32StartAddr);
as given in the example

C:\ti\TivaWare_C_Series-2.1.0.12573\examples\boards\dk-tm4c123g\usb_stick_update

Regards

Hello Amit,

I tried to load new sp and pc like in the example usb_stick_update, but it points to a wrong address.

Can i read and store the sp and pc values directly from the hex file as i receive it from the uart and after burning the hex file onto the controller, load those values of sp and pc to point to the application.

Thank you

Hello Reshma,

What does the SP and PC point to just before the "bx r0" instruction is called?
