STM32F429disco

STM32F746disco

Prerequisite

• Alire Setup Instructions
• Alire GAP index Setup Instructions
• OpenOCD
  • sudo apt install openocd
• Any of these development board:
  • STM32F429disco
  • STM32F746disco

Fetch the Crate

alr get stm32_blinky_demo
cd stm32_blinky_demo*

Configure Board

Edit the alire.toml file by uncommenting the board for which you build: (eg. STM32F429disco)

...
[[depends-on]]
stm32f429disco = "0.1.0"
#stm32f746disco = "0.1.0"
...

Pin Working Cross Compiler (IMPORTANT)

alr pin gnat_arm_elf=12.2.1

Build (Alire)

alr build

Build (GPRBuild)

eval "$(alr printenv)"
gprbuild stm32_blinky_demo.gpr

Build (GnatStudio)

eval "$(alr printenv)"
gnatstudio stm32_blinky_demo.gpr

Program to Board

• Linux, MacOS:

openocd -f /usr/share/openocd/scripts/board/stm32f429disc1.cfg -c 'program bin/stm32_blinky_demo verify reset exit'

• Windows:

openocd -f interface/stlink.cfg -f target/stm32f4x.cfg -c 'program bin/stm32_blinky_demo verify reset exit'

Running on Renode

First make sure you have Renode (>= 1.15.2) binaries visible on your PATH.

Launch the Renode console (at the root of this repo):

renode --console

Then at Renode prompt:

 include @renode/stm32f429_startup.resc

It will launch the Renode script stm32f429_startup.resc. You should see alternating logging of sort:

...
... [NOISY] stm32f429_custom/gpioPortG.UserLED: LED state changed to False
... [NOISY] stm32f429_custom/gpioPortG.UserLED: LED state changed to True
...

To terminate:

quit
