Pico Minitioune problem

[OE8PCK]

I have checked the whole board for hardware mistakes but cannot find any.
Attached is the latest LOG from switch on the stop.

This is the log when I try and start again without turning the Minitioune off.

Could it possibly be a power supply problem?

When I first built my Minitiouner it would run for a while then crash. The clue was in the power LED dimming or going out altogether. The 12 volt to 5 volt buck converter was faulty. I re-flowed the pads on the thing (Ebay Chinese special...) and it has behaved ever since. Have you monitored any internal or even external voltages?

Just an idea, for what it's worth... Good luck. Chris 2E0ILY

Tnx Basil, I will have a look tomorrow.

Hi Tom,
I have checked and monitored all the voltages from switch on until the program freezes.
All the voltages remain constant and in spec.
As I said the program works really perfectly until it suddenly freezes.
I then turn off the Minitioune and on again, and leave the Pico connected and then the program can be restarted and it remains OK until it freezes again.
Thanks very much for your help.

This is the Log that runs with the Mini Tioune. I am not sure it is the same as the log.
It shows when the program freezes.
