### Flashing the Firmware with stlink
ST Discovery or Nucleo boards have a builtin programmer called ST-LINK. With
these boards and using Linux or OS X, you have the option to upload the
`stmhal` firmware using the `st-flash` utility from the
[stlink]( project. To do so, connect the board
with a mini USB cable to its ST-LINK USB port and then use the make target
`deploy-stlink`. For example, if you have the STM32F4DISCOVERY board, you can
$ make BOARD=STM32F4DISC deploy-stlink
The `st-flash` program should detect the USB connection to the board
automatically. If not, run `lsusb` to determine its USB bus and device number
and set the `STLINK_DEVICE` environment variable accordingly, using the format
`<USB_BUS>:<USB_ADDR>`. Example:
$ lsusb
Bus 002 Device 035: ID 0483:3748 STMicroelectronics ST-LINK/V2
$ export STLINK_DEVICE="002:0035"
$ make BOARD=STM32F4DISC deploy-stlink
