Hi,

I have written data at flash memory location starting from 0x0008000, upon power cycle, I need to start running the code from location 0x0008000.I tried below code
application_entry_t app_entry = (application_entry_t) (0x00085000);//APP_START_ADDRESS;
application_entry();

but it is not happening.

Please guide.

If you check your linker cmd file, you have a variable codestart that is pointing to an address, in our generic linker cmd file in SDK, it will be pointing to BEGIN at address 0x080000. You ca update this location for changing the codestart location.

BEGIN : origin = 0x080000, length = 0x000002 // Update the codestart location as needed

You have a codestartbranch.asm file which points to this codestart location.

Please update them and check again if it is resolving your issue.

Also please check on the bootpin configuration in your device.It should be boot from FLASH configuration.

Thanks
