Flash with dfu-util #20

Closed vazhnov closed 1 year ago

vazhnov commented 1 year ago

I see dfu-util mentioned in TUTORIALS.md but not used in the code.

Here is example of successful flashing with the tool to "Sipeed Longan nano" board:

 % dfu-util -l                                      
dfu-util 0.11

P.S.: without --alt 0 it returns an error:

dfu-util: More than one DFU capable USB device found! Try `--list' and specify the serial number or disconnect all but one device

I can try to improve the documentation and Makefile when find how to automate arguments selection.

Hi, thanks for this. There are many other methods for flashing as well, documented on various websites, so I will not add dfu-util process. The Makefile is already configured for using stm32loader if you type make flash.
