@brief Support for the STM32G0316-DISCO board.
|
|
|
|
### General information
|
|
|
|
The ST [STM32G0316-DISCO](https://www.st.com/en/evaluation-tools/stm32g0316-disco.html)
|
|
is an evaluation board supporting a ARM Cortex-M0 STM32G031J6 microcontroller
|
|
with 8KB of RAM and 32KB of ROM Flash.
|
|
|
|
### Pinout
|
|
|
|
In an SO8 package, this MCU uses multi-bonding to run multiple ports to the same pins.
|
|
See [this application note as reference](https://www.st.com/resource/en/application_note/dm00443870-getting-started-with-stm32g0-series-hardware-development-stmicroelectronics.pdf).
|
|
This means the responsibility is on the firmware configurer to take special care when configured IO, ensuring that
|
|
ports are not conflicting on each pin.
|
|
|
|
### Flash the board
|
|
|
|
The STM32G0316-DISCO board includes an on-board ST-LINK programmer and can be
|
|
flashed using OpenOCD.
|
|
|
|
To flash this board, just use the following command:
|
|
```
|
|
make BOARD=stm32g0316-disco flash -C examples/basic/hello-world
|
|
```
|
|
### UART Terminal Interaction
|
|
|
|
Due to the limited number of pins, to get stdio UART traffic, use a USB->UART adapter
|
|
like the CP2104 from Adafruit (http://adafru.it/954). Connect the adapter's TX line
|
|
to the MCU RX pin (PB6, Pin 8) and the adapter's RX line to the MCU's TX pin -
|
|
(PB7, pin 1).
