Mini Pitft stopped working with OS Upgrade
My color mini Pitft display stopped working when I upgraded to latest OS. I now have Kernel 1.20221104-1. I tried following these instructions https://learn.adafruit.com/adafruit-min ... leshooting but got a 404 error on the gethub link. Any ideas?

Re: Mini Pitft stopped working with OS Upgrade
You need to reinstall PiTFT support when you upgrade.
Linux uses a 'monolithic' kernel, meaning everything it needs is part of the same executable file. The alternative is a 'microkernel': a small program that does most of its work by running other programs.
Both options have pros and cons. A monolithic kernel like Linux can upgrade the OS by replacing a single file, but doing so throws away everything you installed on the old one.
Use the same installation process you used last time, and it should start working again.
