LP-MSPM0L1306: How to start the main application after a successful custom BSL

Part Number: LP-MSPM0L1306
Other Parts Discussed in Thread: MSPM0L1306

Hi Champs,

Custom BSL: I use the example project named "secondary_bsl_uart_LP_MSPM0L1306_nortos_ticlang"

Main application: I use a simple example project named "gpio_software_poll_LP_MSPM0L1306_nortos_ticlang"

Case 1:

Keep the projects as is. I can successfully load and start the main application which starts at 0x0000 0000 in flash memory. The BSL starts the main application by a POR.

Case 2:

Now I want to move the custom BSL to 0x0000 0000, and move the main application to 0x0000 2000. How can I start the main application after a successful boot loading? (Now a POR will starts the custom BSL since it resides at 0x0000 0000).


Regards,

Kien Nguyen

    Hi Kien,

    You can directly call jump to function of MCU, to let MCU jump to reset handler of app code: Below is an example for your referencr.

    /* Force a Reset Handler Routine */
    AppStartAddress = *(__IO uint32_t *)(NVIC_APP_VectorAddress + 4);
    ((void (*)(void)) AppStartAddress)();

    If you set app code start from 0x00002000, and then NVIC_APP_VectorAddress should be set as 0x00002000.

    Becareful, if you want interrupts of app code working, you should firstly set the SCB->VTOR for interrupt table address and then enable the app code interrupt.
