@ -172,6 +172,4 @@ Flashing sequence:
There are a number of DFU commands that you can use to flash firmware to a STM32 device:
* `:dfu-util` - The default command for flashing to STM32 devices.
* `:dfu-util-wait` - This works like the default command, but it gives you a (configurable) 10 second timeout before it attempts to flash the firmware. You can use `TIME_DELAY=20` from the command line to change the timeout.
* Eg: `make <keyboard>:<keymap>:dfu-util TIME_DELAY=5`
* `:st-link-cli` - This allows you to flash the firmware via ST-LINK's CLI utility, rather than dfu-util.
