NHS3152 not powering on over NFC while running demo applications or custom code

[acuom]

I have been using the NHS3152 dev boards to prototype for a project and while I am able to flash and run my code while it is connected to my laptop (and transmit data over NFC onto my android phone), it stops working as soon as I disconnect from the laptop.

This behaviour is observed with my own code running on the board and the demo applications supplied. I have already disabled semi hosting. The Blinky application runs (as in debugger shows it is running) but the LED doesn't light up.

Basically, as soon as I disconnect the board, it is no longer recognised by my phone (even though the phone recognises other passive tags). I also connected a source meter to monitor the voltage between Vdd and GND and it falls to 0 even with the NFC field present.

Is the board beyond rescue or can some sort of reset help?

Thank you for this. Will follow it up with them!

Hello,

Did you order the dev board from local distributor? If yes. You may try to Dev Tool Warranty Return Request Form as the link.
