M5Stack Fire core + Plus + M5GO base = psram fails on boot

anichang

If I stack core+base or core+plus works good. If I stack all of the three it fails to boot

The same happens using plain esp-idf, arduino or micropython. I tried many settings (DIO-QIO... changing mhz... and so on) without any result.

What can I do to make it works using core+plus+base ?

Hello @anichang

just wondering - maybe the issue isn't specific to PSRAM but with the power supply? I'd try a different power supply and/or shorter USB cable.

Thanks
