Crash in the sd_mbr_command

[Jason]

Hi,

I try to build the DFU with:

1. S110 V7.0
2. SDK 6.1
3. Eclipse w/ GCC
4. LEDs for DEBUG
5. BOOTLOADER_REGION_START = 0x0003C000

And, always crash (no return) in the sd_mbr_command().

Code as below:

static void ble_stack_init(bool init_softdevice) {
uint32_t         err_code;
sd_mbr_command_t com = {SD_MBR_COMMAND_INIT_SD, };

nrf_gpio_pin_set(LED_1);
if (init_softdevice)
{
	nrf_gpio_pin_set(LED_2);
    err_code = sd_mbr_command(&com);
    APP_ERROR_CHECK(err_code);
}

nrf_gpio_pin_set(LED_3);

err_code = sd_softdevice_vector_table_base_set(BOOTLOADER_REGION_START);
APP_ERROR_CHECK(err_code);

SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, true);
...
...
...

• LED_0 : ON (at start)
• LED_1 : ON
• LED_2 : ON
• LED_3 : Never ON

What is the problem ?

Hi, I'm not sure what the issue could be. Can you try the attached makefile and see if you still get the same problem? To get the correct search path, place it in this path: ..\nrf51_sdk_v6_1\nrf51822\Board\nrf6310\device_firmware_updates\bootloader\gcc\

Makefile

So, what was the problem?

I have this problem as well. No solution so far

[Vidar Berg]

Are you using the same SDK/SD? In any case, SD_MBR_COMMAND_INIT_SD cannot be called if you have branched from the application as the SD is already invoked, hence the init_softdevice check.

The problem was actually somewhere else. https://devzone.nordicsemi.com/question/51697/odd-sd_mbr_command_init_sd-behavior/
