Seems I just bumped into this issue as well with the same board. I’ve tried the 1M bin file and the alternative led files, just in case the GPIO02 was causing some oddities (the blue LED on the board seems to be connected to that pin too). Just like MDLefevere, I’m not getting any AP wifi created but if I plug some LEDs to the board I get the default orange 30 leds.
Interestingly, I’ve tried Tasmota and I’ve managed to drive all the leds and create an AP without trouble. But I miss all the configurability in WLED!
How can I go about debugging this further? Is there a build with extra logging that I can try out? Happy to setup the build environment too.
