SAMD51 bootloader won't jump to application

1

I have been using SAMD51 core and set BOOPROT to 0 bytes to allow bootloader customization.
My workspace have 2 projects:
bootloader
application

The application .ld flash area starts at 0xC000. Also, I have added the offset attribute into platformio.ini:
board_upload.offset_address= 0xC000

The bootloader app, just run the code below to jump tp the application address:

#define APP_ADDRESS 0xC000

static void run_application(void)
{
    uint32_t fw_start_address = APP_ADDRESS + 4;

    /* Rebase the Stack Pointer */
    __set_MSP(*(uint32_t*)(APP_ADDRESS));

    /* Rebase the vector table base address */
    SCB->VTOR = ((uint32_t)APP_ADDRESS & SCB_VTOR_TBLOFF_Msk);

    asm("bx %0" ::"r"(*(uint32_t*)(fw_start_address)));
}

If i set #define APP_ADDRESS 0x0, bootloader app restarts properly.
However, when #define APP_ADDRESS 0xC000, application never gets called.
SP and PC` get lost.

Using atmelsam arduino framework.

Am I missing something here?

Thanks.

Hi @ sylvioalves,

Did you resolve this issue? I have the same problem now. Thanks
