Unable to run my program or examples

[Lezto22]

Hi Nordic developers.

I am developing a custom board using 2 Rigado BMD-300, but I am unable to run my 100% operative program or examples.

At first time I was able to see the rigado DFU service working on thoses chips (it was working) I used nrfjprog --family nrf52 --recover to remove the manufacter firmware then I programmed the Softdevice and the application, but the application does not start.

I was thinking the issue is hardware related, but how is it possible if the manufacter code was working from the first time I powered the devices?

I am able to debugging my code, read back my code from the rigado modules, but no able to start the program.

Info: SDK 12.2 nRF52 (rigado bmd-300), SD: s132, Interface programing: SWD (swdclk, swdio, GND)

Any suggestion?

See you

Hi Kristin,

Yes all the modules are identical, but one module get stuck there, same hardware and same software. The order as I programed each module is the following: Softdevice+Application.

Could this be a defective module? The weird for me is... I am able to debugging it and when it arrives with the manufacter firmware it was working using a DFU service (I removed it to be able to reprogramming using the Nordic SDK)
