stm32duino in Arduino on Raspberry Pi

[odo2063]

Is your feature request/improvement related to a problem? Please describe.
yes

Describe the solution you'd like
Being able to install stm32duino in Arduino on Raspberry Pi.

Describe alternatives you've considered
none

Additional context
It would be nice to be able to compile and flash stm32duino boards from a Raspberry Pi. At the moment we doing a longterm test where all devices are only available by wifi or GSM. So it would be nice to be able to implement improvements in field. It would also great in schools. the raspi4 is powerful enough to be cheap desktop for schoolusage and then it would be nice if your boards could be used besides it.

Hi @odo2063,
As I do not have a Raspberry, I will not be able to work on this stuff.
I guess the main works is to have an arm-none-eabi-gcc toolchain for this target and also check all tools used by the core for upload.

If anyone want contribute to this this will be greatly appreciated.

the arm-none-eabi-gcc seems easy...
https://packages.debian.org/buster/gcc-arm-none-eabi

What else do you need?

i could also give you SSH to Raspi if you like...or you find something with https://www.st.com/content/st_com/en/products/microcontrollers-microprocessors/legacy-mpus/spear-arm-cortex-a9-microprocessors.html

Thanks but I will not have access with SSH due to security policies.
About arm-none-eabi-gcc this require several investigations:

• Which one have to be used depending of the host arch? Honestly, I don't know Raspi ecosystem, what I know is Arduino seems able to handle twice of them (arm64 and armhf)
• arm64
• armel
• armhf
• Which options has been used to build ? (libraries provided? lto support?....), moreover this is not the same version and unfortunately I don't think Arduino IDE was able to deal with as we are able to only reference one.
• Test if all options used is well supported
• Need to be repackage to be installed thanks Arduino but I'm not be able to test.
• ...

What else do you need?

All tools (binaries and scripts) tested and updated in the https://github.com/stm32duino/Arduino_Tools repo.

Hi I found this one

For now consider Raspian as standard Debian on armhf....this will maybe change to arm64 for the Raspi4 in the future

./dfu-util --version
dfu-util 0.8

...seems to compile

I can run any script you want me to...but I am a newbie when it comes to build up a toolchain with my own hands...

Currently, I've no time frame to investigate this at least until next year.
If anyone wants try to work on this will be welcome.

Just FYI:
Raspberry already has the following debian packages:

• binutils-arm-none-eabi
• gcc-arm-none-eabi
• libnewlib-arm-none-eabi libnewlib-dev
• libstdc++-arm-none-eabi-newlib

After installing these packages, you can compile stm32 code on Raspberry. Eg. you can compile this: gdb debugger for blue pill. I've added a list of available commands and the output of arm-none-eabi-g++ -v: gcc-output.txt

What's missing (I think) is the STM32 arduino libraries and their headers in the arduino IDE.
HTH.

@koendv
the main issue is to have n all in one toolchain package (aligned with the gcc version used by other host OS) and as I said I could not test it. So I could integrate it if someone is able to provide and test it.

[koendv]

Fine. If you provide a STM32 board package that assumes arm-none-eabi-g++, arm-none-eabi-ld, dfu-util, ... are in /usr/bin, I can try to compile some examples ("blink") on raspberry and get the examples running on black pill/blue pill. OK?

[fpistm]

When I said "integrate", I mean store it on GitHub and reference it in the boards JSON files.
Not provide it.

[koendv]

OK. odo2063, if I put an arm-none-eabi toolchain up, are you willing to test it?
