GCC compiler for SAMD21

[jachaney]

After searching on the web, I found the Ubuntu 18 solution for getting the GCC cross compiler for M0 type ARM processors. The prescribed solution was:

sudo apt-get install arm-none-eabi-gcc
sudo apt-get install gdb-arm-none-eabi

The results were a big NOPE! I probably need to add a link for the update, but I have not been able to locate one. If anyone is able to help, it would be greatly appreciated.

Thank you,
Jack

Arduino IDE can install Cortex M0 compilers

Arduino IDE can install Cortex M0 compilers

yes, Arduino is feat. SAMD21 cores, but it supports boards, not native ICs: https://www.google.com/search?client=fi ... ino+SAMD21
But there are also small Arduino-compatible development boards for SAMD21 availabe:
https://www.avdweb.nl/arduino/samd21/sam-15x15
To download the Arduino IDE:

Code: Select all

wget http://downloads.arduino.cc/arduino-1.8.9-libuilt-in nuxarm.tar.xz
tar -x -f arduino-1.8.9-linuxarm.tar.xz

The Arduino IDE comes with with the appropriate gcc-compiler (currently C++14 IIRC).

Thank you for the help so far. I understand the Arduino package has an M0 component, but what I am looking for is a stand alone compiler that can be used with Code:Blocks for stand alone development.

You can always build a gcc cross-compiler for your target from GCC sources.

Here are some instructions for doing just that http://gnutoolchains.com/building

Those instructions are for building GCC on Windows but I think you can easily see which parts you can omit for building on Raspbian.

Or see here for further clues:

Or read all the gory details:
https://gcc.gnu.org/install/

In my experience this can take quite some experimentation and head scratching to get built.

Raspbian Buster does include the 'arm-none-eabi' compiler, see my blog on cross-compiling and debugging the NRF52:

I haven't used it on SAM processors, but if you have the necessary startup code, the build process should be similar.
