Hello,
Although my board is not equipped with an external LC filter, I flashed firmware which enables DCDC and this made the chip unresponsive.
Is there any method to make a recovery from this state?

Hi
I'm afraid flashing firmware enabling the DCDC without the necessary HW components will put it into an undefined state that is likely to brick the board, and even if you're able to recover it, it's not guaranteed that it will work as intended because it technically has been operating outside operating conditions.

Hi Simon,
thank you very much for your reply!!
Yes I understood it's likely being a brick, and there shall be no guarantee any more;
but just for testing purpose, is there any way to force recover it?
It's not responding any more from the programming tool.
Thank you in advance!
Hi
What you can try is to run a script continuously running the nrfjprog --recover command, as the device is likely caught in a reset loop, and you basically just need to be lucky and catch it between resets to have any chance of recovering it.
Best regards,
Simon
Thank you, I'll try!
