Arduino for STM32

It' might take some work. You end up having to learn ARM assembler and gcc's arcane inline syntax as well.

This tool can be handy: https://godbolt.org/. Make sure to set the correct compiler.

It looks like 2.5.0 was the version that moved from arm-none-eabi-gcc 10.3.1-2.3 to 12.2.1-1.2 https://github.com/stm32duino/Arduino_Core_STM32/pull/1944

Might be time to migrate to 64 bit Win if your PC supports it.

Thanks. Installing arduino-cli and rerunning CMake gave the same error.

After more time on Google I came across this https://github.com/orgs/stm32duino/discussions/2063#discussioncomment-6414073

Where CMakeFile.txt line is edited to point to local install location.

I've got Arduino IDE 1.8.19 with STM32Duino V2.7.1 installed, on Ubuntu 22.04.

I'd like to get CMake build up and running. I've downloaded CMake_workspace examples to my sketch folder. 1_Blink example compiles no problem in IDE using a NUCLEO_F401RE target.

Next, I've been following the ...

Looks like F0, F1, F2, F3, F4, F7, H7, G4, L0, L1, L4, L5, U5, WB now included.

After updating to v2.1 of STM32duino core, I'm getting "no DWARF2 info found" errors when attempting to debug .elf file compiled with -g option. This was with Segger Ozone on both Ubuntu 18.04 and Windows 10. Reverting to 2.0 fixes the issue.

Anyone else experiencing this? I'll have to do some ...

rtos alone would not solve that 'multi-core' problem. in effect for a real smp, you have one os (e.g. arduino core or rtos) thread running on each core of the mcu. it is a 'brave new world', it may not be surprising if we'd ever see 8 core or more duinos


A start?:

Some form of RTOS is essential to manage the complexity of these increasingly complex Arm cores, hardware debuggers too IMHO.

This guy Dave Nadler does a deep dive on newlib issues with FreeRTOS https://nadler.com/embedded/newlibAndFreeRTOS.html Not a pretty sight.

Fix was documented here https ...

I don't know. Anyway some of the drawback on Windows are the network access and the antivirus...


Hmm, I'm not sure that 'just use Linux because it decides to not worry about scanning for viruses' is a durable argument. It is certainly not an option in work environments. I do have dual boot ...

Thanks for the replies. I sounds like a smarter IDE with incremental build features could provide an improvement on a project by project basis (ie each quick and dirty test project will still drive a new folder / full rebuild).
