cpu freqency promble #27

Closed gaojingqi23 closed 1 year ago

gaojingqi23 commented 2 years ago

The board that i used is ESP32 DEVKIT V1,when i set the cpu frequency 80MHz,USB Test failed. I wasted several hours to find problems, finally i tried to change cpu_freq, 240MHz and 160MHz were successfully ! But I when was trying 80MHz again, it failed. I don't konw it is just only my problem or there is a request to set cpu_freq bigger.

240MHz no less (it's for ESP32, not ESP8266), it's surprising you had results at 160MHz though
