Hi,
I'm running a custom board with MKW41Z on it, powered from 3V3. In my hardware initialization routine (inspired from the FRDM-MKW41 examples), I'm increasing the output voltage of the built-in DC regulator from 1.8V to 2.6V. When that change takes effect, the board continues to run as expected, but the debugger (an LPCXpresso LPCLink 2) disconnects and the IDE (MCUXpresso 10.2.1) throws an error and the debug session stops. The board continues to function as expected. Then I have to reset the board a couple of times until I'm able to erase the flash and reconnect with the debugger.
Hi Alexandru, I hope you're doing well!
Could you please try attaching the debug probe after the voltage change is performed to see if it can connect and continue the debug session?
This can be done while the probe is connected to your board, by choosing this option in MCUXpresso:
Please let me know if you still have issues.
Best regards,
Sebastian
Thanks, will try this and let you know :smileyhappy:
