Default Zephyr Peripheral Mapping:
The ART-Pi board features a On-board ST-LINK/V2.1 debugger/programmer. Board is configured as follows:
UART4 TX/RX : PA0/PI9 (ST-Link Virtual Port Com)
LED1 (red) : PC15
LED2 (blue) : PI8
USER PUSH-BUTTON : PH4
Programming and Debugging
The art_pi board supports the runners and associated west commands listed below.
| flash | debug | rtt | debugserver | attach | |
|---|---|---|---|---|---|
| openocd | ✅ | ✅ (default) | ✅ | ✅ | ✅ |
| stm32cubeprogrammer | ✅ (default) |
Note
Check if your ST-LINK V2.1 has newest FW version. It can be done with STM32CubeProgrammer [3]
Flashing
First, connect the art_pi to your host computer using the USB port to prepare it for flashing. Then build and flash your application.
Here is an example for the Hello World application.
Run a serial host program to connect with your art_pi board.
$ minicom -b 115200 -D /dev/ttyACM0
or use screen:
$ screen /dev/ttyACM0 115200
Build and flash the application:
# From the root of the zephyr repository
west build -b art_pi samples/hello_world
west flash
You should see the following message on the console:
*** Booting Zephyr OS build v4.2.0-3809-g1d6b6759aa1a ***
Hello World! art_pi/stm32h750xx
Blinky example can also be used:
# From the root of the zephyr repository
west build -b art_pi samples/basic/blinky
west flash
To flash an application that requires loading firmware on external flash, see ART_PI Externloader [4]
Debugging
You can debug an application in the usual way. Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b art_pi samples/hello_world
west debug
