NRF 52832 - Is a bootloader required?

[santa_cruz11]

Is a bootloader required to flash code to the nRF-52832?

I built a custom board with a blank nRF52832-QFAB-R. I'm able to run through the tests on the Segger J-Flash V7.58b (flash & verify), but when I try to debug my application in Visual Studio Code, I get an exception that

 

Resetting target
Run to 'main' timed out. Trying to pause program

I'm able to flash and execute my code on a nRF-DK development board, so I don't think it's a software issue.

I'm using the same header and pinout suggested in the PCA10040_Schematic_And_PCB.pdf, and using a J-Link PLUS to flash.

Is a bootloader required, or should I be looking for a hardware issue?

Thanks,

Bill

Hello Bill,

A bootloader is not required so the issue is probably elsewhere, often a missing LF clock is the issue on custom HW if you did not include the external crystal. I see you have another case also, that is HW related, I will provide more feedback in that case.

Thanks.
