The best way is to fix the app. Such major downgrades are firmly uncharted territory, and aren't supported. If you have errors, you need to figure out yourself how to fix them - but if you provide the logs, we can try to help.

Hi,


Currently we are building a Yocto image based on Hardknott release, which includes python 3.9.4. Due to a App constraint, we have to downgrade Python3 to 3.8. I tried copying over 3.8.5 bb file and associated poky/meta/recipes-devtools/python/python3/ folder, but the building failed. What is the best way to switch/downgrade python3 version?


Thanks,

Lijun
