[RESOLVED] RA6M3 FSP Application Example r11an0497 with RA6M3 EK Board (FSP v5.4.0) app_ra6m3_primary Not buildable (Check Python Linkage)

Did you follow the app-notes instructions from section 3.2 to configure the Python environment?

Hi JimB, thank you for the prompt response and helping me with this.
Yes I have.


Still same issue



Wilson Quah

The Python signing script is failing, as the text doesn't wrap to show the full invocation of the script, I cannot tell what might be the problem with this step.

JimB,
Have you check out the project and do a compilation on your side?
Is this issue hardware/OS dependent?
Or is this issue happening in the git repository Renesas provided?

Wilson Quah

I have not tried to build this project myself. The issue with the Python script is configuration issue.

I am sure that someone tested the code before uploading to the repository.

Can you copy / paste the invocation of that script that I highlighted above that would show the arguments to the script?

JimB,
Thank you for following up.
Here is my build output:

JimB,
Apologies for the confusion. I ran the same code in another platform and it works fine.
The issue was mainly due to my e2studio not using the correct python (I have more than 1 python version).
This is my successful build log from another platform

Hi,

I am running into the same issue. Can I know how you resolved it? I have only 1 version of python installed on my system. May I know which platform you ran your code in that was later resolved in?

Thanks,

Adithi K

Hello Wilson,

We are glad your issue is resolved.

Thanks for sharing with us your solution.

If you will check the requirements on the specific app note you will see that the python version required for the specific set-up or having later versions of these tools is:

Thanks and Regards,

IK

Hello adithi ,

Could you please share your FSP version and e2studio version? 

Also which python version you currently have installed?

Thanks and Regards,

IK

Hii IK_Renesas ,

I just resolved this issue. i was using python 3.13 and my code was not building and was throwing the error mentioned above. I uninstalled it and installed python 3.11 and installed all the required packages. and the code got built. FSP version was 5.6.0.

Thanks and regards,

Adithi K
