### HOWTO update microRusEFI Firmware
|
|
|
|
The best way to update microRusEFI firmware is using rusEFI console "Auto DFU" mode.
|
|
In AutoDFU a few things happen once you click the "Update Firmware" button.
|
|
|
|
0. AutoDFU procedure works if your Windows device manager shows "STMicroelectronics Virtual COM Port" in "Ports" category.
|
|
|
|
|
|
|
|
1. rusEFI console finds your microRusEFI device serial port and sends it a command to reboot into DFU mode.
|
|
|
|
It is expected that microRusEFI would stop blinking the blue light and reboot. It is expected that Virtual COM Port
|
|
would disappear from Device Manager and "STM Device in DFU Mode" device would appear in "Universal Serial Bus controllers" category.
|
|
|
|
|
|
|
|
2. rusEFI console gives Windows 3 seconds to re-enumerate USB device from Virtual COM Port to DFU Device.
|
|
|
|
Now the programming begins and the expected output is along the following lines:
|
|
|
|
```shell
|
|
Giving time for USB enumeration...
|
|
Executing .\../misc/install\DfuSe/DfuSeCommand.exe -c -d --v --fn ../firmware/deliver\rusefi.dfu
|
|
1 Device(s) found :
|
|
Device [1]: STM Device in DFU Mode, having [4] alternate targets
