PSRAM ID read error: 0xffffffff

Postby JohnSmith1155 » Sun Jun 13, 2021 6:30 am

Hello,
We recently purchased a new esp32 wrover module. Every thing was working just fine when it just started failing by giving the following error,

PSRAM ID read error: 0xffffffff

Any suggestions? There are no peripherals connected to the ESP32 and now it does not even run the Bare Minimum example in the arduino IDE.

Thanks.

You can't just run a wrover *module* by itself; what are your connections to it?
