- waiting for download
I have a custom board with a ESP32-S3-WROOM-1 module. The USB_PHY_SEL eFuse has been burnt, however the device cannot be detected by dfu-util when in download mode.
Using a separate USB-UART converter on UART0 I can see that it's in download mode, and flash it via UART. Also, I can run a simple application that enables USB-CDC through TinyUSB and this works fine.
I have tried on MacOS as well as Windows and it just doesn't seem to work. Is there something I'm missing?
Attached is the eFuse summary, and below is the ESP-ROM version (are there multiple revisions of the ESP32-S3 chip?)
Code: Select all
