LED dont work on bootloader project on custom board.

[Khawaja]

Hi,

I am testing simple code on various project on my custom board. I have 4 Leds on custom board.

for (int i=0;i<50;i++)
{
nrf_gpio_cfg_output(i);
}

I have LED connected to pin P0.9 P0.10 P0.12 P0.22 

when I run the central project it turns on leds perfectly fine but when I run it on secure bootloader project it just turn on LED connected to pin 22. 

I am calling the function at start of main.

I am unable to understand the reason of this behavior.

Kindly guide,

Kind Regards,

Hi Khawaja, 

The bootloader is no different from the application. It's just the same as an application but located at different space in flash and is executed before the application /softdevice. 

How did you test your setup ?  Do you let the bootloader stay in the DFU mode ?

Please take a look at our example, we turn on LED1 (P0.17) when we are in the DFU mode.

Hi Hung, 

Thanks for your response. I think reason is different than stated in the question so I will open a new ticket and discuss in that. 

Kind Regards,
