A stupid mistake on the boot.py forced me to do a "safe" boot. Connected the 3.3v to the GP28, did a reset and it is not starting anymore.

Please, does someone have any trick or advice to try on the board ?
Thanks

The 3.3 regulator of the WiPy is current limited at 2.8 Amps and thermally protected, the switching transistor at the input is rated at > 6 Amps. That looks all pretty robust. Can you tell, whether there is still 3.3 V on the output? How do you supply the Wipy? Is Vin fine?
