bootloader jump to uapp

[mehmetkaradag]

hello,

i am using IMXRT1170. i want to jump other sector of the flash. i am on core M4. but i receive hard fault. code is below. 

flash base address is 0x800_0000 in core M4. isn''t it?

#define USER_APP_BASE_ADDR (0x8010000U) // sector2

void(*userApp)(void);

uint32_t svalue = *(volatile uint32_t *)USER_APP_BASE_ADDR;   //received UAPP MSP val.

__set_MSP(svalue);

    uint32_t resethandler_address = *(volatile uint32_t *) (USER_APP_BASE_ADDR + 4); //received uapp reset handler.

    userApp = (void*) resethandler_address;

GPIO_PinWrite(GPIO9, 3, 1U);

userApp();

And as i learn is vector table is in RAM that's why i don't change vector table's location in userApp. is it correct?

thanks for help.

Hi @mehmetkaradag,

Are you still experiencing this issue?

I noted that you created a new community post where you mention that you successfully jump to userApp. If this is the case, I will continue supporting you on the newer topics rather than this one.

BR,
Edwin.
