Hi, did you found any solution? Just soldered my first sample out of a 20-pcb production and, in comparison to the hand made prototype, it fails also during caraboot "net". regards |

If anyone sees the same issue: Check your GPIO-pins: Some of those are required to be LOW or HIGH during bootstrap. AFAIK a floating GPIO is ok (internal pull-up/down). In my case I used an external circuit on GPIO17 which pulled-down to GND (instead to pull up to 3V3) |
