ARM64 support
ChaimEvans opened this issue · comments
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
CMake Error: The current CMakeCache.txt directory /home/pi/tmp/LCD-show/rpi-fbcp/build/CMakeCache.txt is different than the directory /home/pi/LCD-show/rpi-fbcp/build where CMakeCache.txt was created. This may result in binaries being created in the wrong place. If you are not sure, reedit the CMakeCache.txt
CMake Error: The source "/home/pi/tmp/LCD-show/rpi-fbcp/CMakeLists.txt" does not match the source "/home/pi/LCD-show/rpi-fbcp/CMakeLists.txt" used to generate cache. Re-run cmake with a different source directory.

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.
- Changed all "pi" in code to "ubuntu".
- Install those manually:
sudo apt-get install libraspberrypi-dev
sudo apt-get install xinput-calibrator - Comment this line
sudo dpkg -i -B ./xinput-calibrator_0.7.5-1_armhf.deb
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
