dfu-util: Error during download get_status with Longan Nano

thinxer commented 4 years ago

I compiled the project on both macOS and ArchLinux, but could not flash successfully. The device could be discovered successfully. However, I am getting error on get_status after downloading consistently.

dfu-util: Error during download get_status

The board itself seems to be okay and could be flashed successfully on Windows with the GigaDevice DFU tool.

I've got the exact same problem with Ubuntu 19.04. It works for me when using https://devanlai.github.io/webdfu/dfu-util/ (in Chrome). It still shows the error but at least the flashing is successful.

Upstream has added the support for Longan Nano and exhibits the same error.

Any solution for this?
