This display uses a different driver to the Waveshare display supported by the Portsdown build. I think that you need to do 3 things:
1. Copy the driver tft35a-overlay.dtb from
https://github.com/goodtft/LCD-show/tree/master/usr, to the folder /boot/overlays. Also copy the file into the same folder with the name tft35a-overlay.dtbo.
2. Edit the file /boot/config.txt and remove the line "dtoverlay=waveshare35a"
3. Insert the lines:
Code: Select all
dtoverlay=tft35a:rotate=90
dtoverlay=ads7846,cs=1,penirq=17,penirq_pull=2,speed=1000000,keep_vref_on=1,swapxy=1,pmax=255,xohms=60,xmin=200,xmax=3900,ymin=200,ymax=3900
and save the file.
Then reboot.
Most of the information and files are here
https://github.com/goodtft/LCD-show, but you only need to load the drivers, not the calibration bits.
I hope this works for you, but I cannot test it. Good luck!

If you type dmesg, you may see the error message relating to the ads7846. Just post the text here and I will have a look.
