Zephyr project on STM32

   Zephyr Workbench, a VSCode extension to manage Zephyr on STM32.
It enables users to easily create, develop, and debug Zephyr applications.
Main features:
  • Install host dependencies.
  • Import toolchain and SDK.
  • Create, configure, build and manage apps.
  • Debug STM32.

Build Errors with STM32L476 Discovery Board

Posted by St3v3 on 2015-11-16 01:21

Hello
First I was successful in building and deploying a small program to the STM32F401 Nucleo using nucleo-f401re_hal_lib. That all works.

Now I’m trying first steps with the STM32L476 Discovery using stm32l476-disco_hal_lib. With only a main function I get errors like this:
fatal error: ffconf.h: No such file or directory ff.h /stm32l476g-disco_hal_lib/Middlewares/Third_Party/FatFs/src line 27 C/C++ Problem
(Yes that file does not exist)

multiple definition of `_sbrk’ syscalls.c /L476-1/src line 115 C/C++ Problem
(_sbrk is in \startup\sysmem.c and in \src\syscalls.c)

Has anyone seen the STM32L476 Discovery board to work with the HAL in System Workbench?
Do you have a small project that builds with the stm32l476-disco_hal_lib that you could send me for inspection?

Any suggestions?

thanks

Last week I was at a ST seminar where we built and ran several projects on the STM32L476 Discovery board.

I used:
System Workbench (latest)
CubeMX 4.11
L4 HAL 1.1.0
ST-Link Utility 3.7.0

The simplest example using CubeMX is:
1 - Create new project. Select STM32L476VGTx (LQFP-100, 1024K Flash)
2 - Left-click PB2 & PB8 and set to GPIO_Output mode (these are the user LEDs on the board)
3 - Open Project->Settings and give the project a name and location. Select SW4STM32 as the toolchain.
4 - Generate the code.
5 - Import project into System Workbench. Open main.c and scroll to the bottom.
6 - Within “USER CODE BEGIN WHILE” / “USER CODE END WHILE” add to the while loop:
HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_2);
HAL_Delay(100);
HAL_GPIO_TogglePin(GPIOE, GPIO_PIN_8);
HAL_Delay(100);
7 - Save, Build.
8 - Debug As “AC6 STM32 C/C++ Application” and specify the target as ST-LinkV2-1 with SWD connection.

Admire the blinking lights.

Thanks very much for the clear instructions. I’ll give that a try.

I have been somewhat succesful _not_ using CubeMX but I had to delete the Flash File System and USB Middlewares out of the project to get it to build. I’ll try using CubeMX as you have detailed above!
