Basically the agreement is you can use them for any purposes as long as the code is only being used on STM hardware.
Atollic truestudio stm32f4 project license#
I read the license agreements in the root of both packages and I think they’re quite fair. There are two code packages from STM that I used when putting this together, the firmware for the Discovery board itself, and the Standard Peripheral Library for the chip family.

I think using an external ST-LINK/V2 debugger would also work (see section 6.3.5 of the user manual).Īlso as Blargian mentioned, the clock speed must match the actual speed the microcontroller is running at.Recently I started a repository that houses a template which may be used to compile STM32F0 projects with a GCC toolchain. If you apply this fix, note that PB3 will be connected to SWO, so you can't use PB3 anymore. It is located on the bottom side of the board (the side without the LCD), near the SWD connector. To apply this fix, apply judicious solder to SB9, as indicated in Figure 4. By default, SWO is disconnected! This means you can't get any output back from the device for any of the SWV features. In section 6.13 of the user manual, it indicates that solder bridge "SB9" controls the SWO (Serial Wire Out). I will refer to the document "STM32F429ZI Discovery Kit User Manual" (search for "en.DM00093903" or "UM1670") as "the user manual" in the below paragraphs. Is it possible I've missed something in the setup when using CubeMX? I followed Atollics recommended setup for printf redirect exactly but nothing shows up in the SWV console.Īlthough Blargian already gave his answer as a comment, I thought I should formally answer in case anyone has the same problem. int _write(int32_t file, uint8_t *ptr, int32_t len) When I step through my code and get to that printf("hello") line it just skips over it like it doesn't exist and there is nothing printed to the SWV console.īelow is a picture of my debug settings and the modified version of int _write which resides in my syscalls.c file. I am however struggling to get this to work.

I followed the steps in this article which explains how to setup printf redirect to the console by generating a syscalls.c file and making some changes to the int _write function in that file. When I run debug it programs the board perfectly. I used STM32CubeMX standalone to generate a project for Atollic TrueStudio and then modified the main.c files infinite loop as follows to blink an LED on and off every 2 seconds and to printf a message to the console. Currently I'm trying to figure out how to use the debugging functions of this M4 Cortex, specifically the SWV ones. I recently got an STM32F429 Discovery dev board which I have been playing around with.
