I bought the S3R8V's off digikey as engineering samples so maybe that was the cause of my issues? I made multiple of these boards and could never get the PSRAM to work. I could upload and run code fine when PSRAM was disabled.

I swapped the S3R8V for the ESP32-S3FH4R2 and that worked without issue ...

I soldered a wire to improve power distribution but it made no difference.

Thanks for pointing that out, I get conflicting reports about the eFuse:

esptool.exe flash-id:

Flash type set in eFuse: quad (4 data lines)
Flash voltage set by eFuse: 3.3V



espefuse.exe summary:

Vdd fuses:

Thanks for the response!

Sorry for not including the flash layout. I did have the 0.1/1uF caps on my VDDSPI rail.

I have a feeling that this could be a power issue. Does enabling PSRAM cause the ESP32 to draw more power? I have a 2 layer, 0.33oz copper, flex PCB so power is a real concern. Looking ...

Hello, I trying to test my hardware but whenever I enable PSRAM in Arduino ide I get boot loops. It doesn't matter what is in the script. When PSRAM is "Disabled" things run fine but if use "OPI PSRAM" I get these bootloops:
