1. I tried changing the daplink file in maintenance mode with no luck

2. Tried changing the cfg files with no results

3. No drag and drop working with precompiled hex files
   The interface firmware FAILED to reset/halt the target MCU

Working with your dev board has been the most difficult experience of my life, I am frustrated with this device. This is my university project and I dont understand why it is still sold on the market with so many issues.

For starters it doesnt integrate with keil, there are always errors (Soft device, rom errors etc etc)

Please solve the upload problem, I am banging my head since the last 12 hours to get this up and running.

PS the upload problem started today and the upload worked fine before
