ALL-H3-CC H5 & Waveshare 3.5inch RPi LCD

Hi all! New here, just got the board mentioned above, and the touch screen. I’ve got Raspberry Pi running just fine via the HDMI, but the Waveshare touch screen is just white.

I’ve tried following one this post but it’s for a different board and when trying to run sudo ldto merge spicc-cs1 command I get an error, even after confirming all packages are installed.

I’m connecting with XPT2046 by the way.
