Mbed Studio compiling error

#1

Hello,

i tried to compile the “firmware-st-b-l475e-iot01a” project in Mbed Studio.
After cloning the repositorie, i had to update the mbed-os version to 5.3.2.
Then i checked out the last commit from all sub repositories.
But after all i still get an error from mbed studio.
(Python 3.9 is installed)

File “c:\Users\xyzxyz\Mbed Programs\firmware-st-b-l475e-iot01a/mbed-os/tools/make.py”, line 192
print mcu_toolchain_matrix(platform_filter=options.general_filter_regex)
^
SyntaxError: invalid syntax

Did someone fixed this error already?

Greats

The Mbed OS version does not look right, it should be this exact revision (based on Mbed OS 5.15):

https://github.com/janjongboom/mbed-os/#9366d8d3db62528deb1d55a44fcd58997a466fa2

The error you see is because the version of make.py that you now have was from before Mbed OS gained Python 3 compatibility.

@AssKicker Are you able to set the compiler there? I think Mbed Studio might use ARMCC6 by default instead of GCC.

Im trying to compile it from the mbed studio gui.
Do i have to install other tools next to mbed studio, to run your command?

Hello,

here my short feedback from my side.
First of all … i compiled and flashed the ST Board successfully with Mbed Studio :slight_smile: .

After your hint (@janjongboom ) I decided to install the toolchain according to the instructions in the github repos (firmware-st-b-l475e-iot01a).

Afterwards I was able to compile and flash the project with the GNU Arm Embedded Toolchain and the Mbed CLI under windows.

Then i copied the project to the mbed studio workspace and was able to switch the default compiler to GCC (Arm Mbed Studio - Switching to GCC).

After this i was able to compile and flash the progam.

HI,
I’m also trying to repeat the work on Windows, but I’m stuck in the comipling phase, since I didn’t know the exact python version used for the toolchain buiding, I installed the newest one (python 3.12.1), then compability errors happen. So which version should I use for the toolchain?

To anyone who may take an interest, building mbed cli upon Python 3.8 will be OK.
