User Interface

Flashing

As no usb connector is present on the device an external programmer must be connected to the board for flashing. You can use JTAG or STLINK programmer.

JTAG:
  - JTDO: PB_3 / P39
  - JTDI: PA_15 / P38
  - JTCK: PA_14 / P37
  - JTMS: PA_13 / P34

STLINK:
  - NRST: NRST / P7
  - SWCLK: PA_14 / P37
  - SWDAT: PA_13 / P34

STM32 Loader

To flash RIOT on the board, after connecting the UART-USB bridge, just run:

BOARD=im880b make flash

This uses the stm32loader script to erase the memory and flash it interfacing with the STM32 ROM bootloader.

Connecting via Serial

The default UART port is the USART1, there is no usb connection a USB/TTL converter must be used to connect to the board TX & RX pins. The default port is /dev/ttyUSB0. The pin connections are:

USART1:
  - TX: PA_9 / P30
  - RX: PA_10 / P31

BOARD=im880b make term
