The description has not been entirely clear abouth the necessity of a ground connection between the fpc connector and usb-serial device. While this is essential, it is not obvious from the pictures provided. This is hereby fixed.

On uConsole keyboard back,there is a **UART** port which can be used with `stm32flash` to flash keyboard stock firmware
|
|
|
|
Especially when your keyboard met problem
|
|
|
|
here is the process:
|
|
|
|
* put the switch 1 ON
|
|
* connect uart with a **fpc 6p connector 0.5mm** to a serial-usb converter
|
|
* use stm32flash to flash bin file
|
|
* put the switch 1 OFF
|
|

3 is TX(PA9)
|
|
4 is RX(PA10)

|
Do not forget to **also connect GND** (ground) between the fpc 6p connector and the serial-usb converter.
|

|
## Flashing command
|
|
|
|
```
|
|
$ sudo stm32flash -w uconsole.kbd.0.4_48mhz.bin -v -S 0x08000000 /dev/ttyUSB0
|
|
```
|
|
You can get uconsole.kbd.0.4_48mhz.bin from https://github.com/clockworkpi/uConsole/tree/master/Bin
