Hi @Gayatri

Welcome to Toradex community.

Could you provide the hardware and software versions of you’re setup?

Please note our new BSPv5.x supports python3.8 and hence you need to build a Custom imageto add the latest python packages.add IMAGE_INSTALL_append=“python3” line in local.conf file to include the python3 package.

Hi @ashok.tx

The below are details for my setup:

Angstrom v2017.12 - Kernel
Apalis-iMX6_LXDE-Image 2.8b7 20210420
Toradex ixora carrier boardV1.1(iMX6Q) hardware we have.

Will it be possible to update python3.8 from python3.5 on my setup? Please suggest.

Thanks and Regards,

Hi @Gayatri

Usually, some of the recipe versions are tied to a specific branch, so you would need to look for a newer phyton recipe from a newer branch. It’s not a trivial task as you would need to fix all dependencies.

There may be some python3_3.8.2.bb recipes on other branches you may use to upgrade.
