I’m having a ton of problems also. I’m not even able to run the first couple of lines of the tutorials without having errors thrown at me.
cd
curl -SLs https://apt.adafruit.com/add-pin | sudo bash
sudo apt-get -y install raspberrypi-bootloader
sudo apt-get -y install adafruit-pitft-helper
I got the curl to run by just adding the addafruit repository minus the add-pin but I feel it’s causing me to be missing somoe things I need.
rspberrypi-bootloader seems to install fine
the pitft helper only pratially installs & throws a size mismatch error so I can’t even run the helper.
Tried editing the config without the helper through the instructions but that didn’t do anything either.
I’m using a totally generic 3.5 touchscreen I found from China.
Thanks for the heads up on previous versions working. I think I’ll try setting it up in an older retro version & then update if I get the screen working.
