Actually got a little further this time.
It appears to erase the chip but when I attempt the flash, it fails at 20%.
That sounds to me like a bad connection between the DAPlink and the device. I am getting sometimes errors while flashing a firmware with DAPlink and pyocd, not sure why. That’s why I prefer JLink. It works more stable.
Only thing I can propose here is, check the DAPlink connections again and retry until it works.
You don’t know how many times I have tried this. At least 30+ since this last post.
Do you think an Arduino Uno could act as an interface for this RAK board? I’ve seen other products that could be connected to the Uno and flashed with specific firmwares when they weren’t working properly.
Never heard of a solution where the Arduino UNO could replace a JLink or DAPlink with a Nordic MCU.
