Hi,


Currently we are building a Yocto image based on Hardknott release, whic= h includes python 3.9.4. Due to a App constraint, we have to downgrade Pyth= on3 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 v= ersion?
