nRF52833 Custom uart Bootloader development using gcc failed.

[Swapnil Karkare]

Hi,

We are trying to develop custom uart bootloader firmware without using MBR. also we are not using softdevice.

Here are some linker definitions which are implementation.   

 

the following error i got. not able to debug or program the device.

Please advice how do i resolved this?

Hi Swapnil

We strongly recommend using MBR here for simplicity's sake. Can you explain the reason you don't want to use it? You will need something similar in order to move around on the application after it is transferred anyway, so I don't see why you wouldn't want to use it.

Best regards,

Simon

Yes Simon,

You showed us MBR is part of softdevice. s140 which will required in our project. I will try to develop firmware with MBR. and let you know if i found any issues.
