Cross compiling on a Raspberry Pi... #93

Open dl9sec opened 4 years ago

Hi,

i tried to cross compile the stuff on a Raspberry Pi 3. The toolchain mentioned at "Prepare ARM Cross Tools" can not be used on a RasPi. But i found a precompiled toolchain for the Raspberry Pi at https://github.com/vanbwodonk/gcc-arm-embedded-build-armhf. This toolchain is more recent (8-2019-q3-update). Differing from the description there, i used the following lines to install the toolchain:

wget https://github.com/vanbwodonk/gcc-arm-embedded-build-armhf/raw/master/pkg/gcc-arm-none-eabi-8-2019-q3-update-linux-armv7l.tar.bz2 tar -xvf gcc-arm-none-eabi-8-2019-q3-update-linux-armv7l.tar.bz2 sudo cp -r gcc-arm-none-eabi-8-2019-q3-update/* /usr/local/ sudo rm -r gcc-arm-none-eabi-8-2019-q3-update

Additionally i added the following line at the end of ~/.profile:

PATH=/usr/local/usr/local/arm-none-eabi/bin:$PATH

My first attempt fails to get the toolchain work on my Raspbian Stretch (Debian 9) because the toolchain needs glibc 2.28, but Stretch uses 2.24. So Raspbian Stretch must be updated to Buster (see https://pimylifeup.com/upgrade-raspbian-stretch-to-raspbian-buster/) to get the toolchain work.

After upgrading Raspbian make runs well and the binary was built.

Hope this helps if someone want to cross compile on a RasPi...

Regards, Thorsten

I am currently using local repository of NanoVNA and Eclispe IDE. Combination of git and EGit (Eclipse plug-in) really does not yield to easy actual code debugging. I have successfully used TCF (Target Communication Framework ) on RPi on another project. I'll give your GREAT idea try. THANKS

This is really great, thank you.

Not really, I still cannot analyse / debug the software. I get two errors - if run locally - cannot execute .efl file if run on RPi I get I/O error loop and cannot find from where... I realize I cannot run STM32 I/O on RPi, but sure like to just set breakpoint on "main.c" and print the variables contents on standard console. Is that so much to ask? There is "printf" debug option on IDE /TCF I am trying got implement.
