Hello,

when I chose Flash Mode --> OPI 80MHZ, the ESP32-S3 N8R8 reboots and I throws this error message:

Octal Flash option selected, but EFUSE not configured!

Can somebody tell me what I need to configure on the EFUSE to get the Octal speed PSRAM working?

Thanks!

Likely you need to run the espefuse.py line at the end of this section.
