NRF52832-QFAB-R loader script

[sboudaud]

Hello,
I modified the ble_app_blinky example to work on our board (removed leds and buttons) and modified the board pca10040.h
the new application worked on the devkit but not in our board.
As the chip in the devkit is not the same used on our board (NRF52832-QFAB-R) is there any thing that I need to modify? like ble_app_blinky_gcc_nrf52.ld?

Thanks.

Is it the error handler that catches something?

Have you tried to monitor the log? 

[sboudaud]

The reset Handler is called:

I want to add a new result:

As I said I used to program the custom device with https://www.silabs.com/documents/public/user-guides/efm32lg-stk3600-ug.pdf

We used to use that device to program the NRF51 in our old hardware version and to program the main MCU, and we never had such issue.

I tested today to program our custom board using NRF52 DK by making the connection described here: https://devzone.nordicsemi.com/f/nordic-q-a/14058/external-programming-using-nrf52-dk

Using the NRF52DK resolve the problem. have you any Idea of the difference between the two board? As the production lines are already equipped with the silabs devkit it will be easier to make just a firmware changes than adding new equipment !

Hello,

I am not familiar with the DK that you link to, what it uses, and how it works.

I see that you uploaded a picture from the callstack, where the reset handler was called. Can you show me the rest of the callstack as well? Maybe it can give some hints as to what went wrong.

BR,

Edvin
