The latest arduino-esp32 I2C have a problem, I checkout out to the e63aa4065092c9a3a0547b2649a509585866ce87 can fix the problem.

cd ~/Documents/Arduino/hardware/espressif/esp32
git checkout e63aa4065092c9a3a0547b2649a509585866ce87

@bin 在 cannot boot M5Cloud firmware on M5Stack FIRE 中说：

change SPI MODE: DIO

You tried to burn the PSRAM version firmware in DIO mode. Is PSRAM still not initialized?

user this template:

change SPI MODE: DIO

What is the serial log?

Awesome!!!
