TMS570LS1114: Change Entry Point of processor during runtime

Karim Seif

Part Number: TMS570LS1114

Is it applicable to change the entry point of our system during runtime so that when applying a reset the processor starts from a different address?

Hi Karim,

After reset the processor will always execute from the address 0x00000000(RESET Vector),

As you can see from here it will jump to the initialization function. So that means if we want to change the entry point then we should need to rewrite a different address at the 0x00000000 address at run time.

And it is a difficult thing in the TMS570LS1114 device have only one flash bank.

And we have to rewrite to the same flashback while the code is running on same bank, this is not possible by FAPI.

Please refer below thread to understand this:
