ARM64 support #31

Closed ChaimEvans closed 1 year ago

ChaimEvans commented 4 years ago

In arm64, it can be installed successfully, but after that, the system can't start, and HDMI outputs a lot of words that can't be read clearly.I can't control it. It seems that I can only flash the system again. (raspberry 4b, system:2020-08-20-raspios-buster-arm64)

After I run ./LCD35-show Terminal shows

At first I was in the same situation as you. In order to solve this problem, I deleted the code "reboot" in "LCD35-show" to make sure system doesn't restart automatically. Then solve various problems, such as dependency and compilation errors.Finaly manual restart until no error is reported, but still unable to start system.

Should be compiled for arm64. @ChaimEvans can you please share your changes?

I tried on x64 Ubuntu Server 20.04.02.

Run sudo ./LCD35C-show, no errors. But the screen doesn't show anything(just change from gray to black after reboot)

Someone apparently made it work for waveshare-35A: https://github.com/marcin-chwedczuk/waveshare-35A-raspberry-pi-64-driver
