Trouble uploading firmware to ESP32-S3FH4R2 using DFU

Postby pedrodel » Tue Apr 01, 2025 5:47 pm

Good afternoon all,

I am trying to upload my code to my esp32-s3fh4r2 using DFU and VSCODE and ESP-IDF. I was able to upload once using the dfu-flash command, but now I can't upload anymore.

The error: https://imgur.com/hZczCSQ

I am able to detect my device, I have the driver that I installed following the documentation and have my util-dfu set as environment variable too.

How should I proceed?

Updates:

I was able to upload the binary by specifying the esp32 device, but now the device it is in a state where it keeps disconnecting. The USB disconnect sound keeps triggering every 1s. I cannot recognize the device for DFU anymore, but my computer recognizes the USB.

Errors:
