Reflashing the Bit 2.0

đź“‹ Support
#1

I’m trying to reinstall the firmware on the Bit 2.0. I’ve done so before using esptool and it worked (via /dev/cu.usbmodem11101)

This time, however, I flashed the Bit 2.0 with a TinyUSB program via the Espressif IDE. The LCD is now white. The port that used to be be there is no longer visible within the Espressif IDE or the Arduino IDE. Instead, I have a TinyUSB instance visible on the USB.

Apparently the user manual for the S3 processor says that I should ground GPIO0. Does this correspond to one of the buttons on the Bit 2.0? Or is there another way to reflash the board?

According to the schematics, the Serial Clock line for the Wacky Robots connector goes to GPIO0.
Try to connect the console to the Bit 2.0 and send what it says.
