Hey guys
i have a 4.3 inch waveshare LCD for my rpi4
it used to work earlier
but now when i try to use the driver given, it doesnt work
ref: https://github.com/waveshareteam/LCD-show
What was your setup when it worked and what have you changed?
did a fresh raspian OS install
honestly, i dont remember what i did to get it to work
We have all been there!
thought it was the last, i would care about it since it worked
smh
What version of the kernel are you currently running?
I’m looking at the last commit dates being 6 years ago, and configs have changed – especially the DTB
should be ~6.6 if i remember
`uname -a`
(Assuming you have shell access)
gimme a sec
Linux pi 6.6.51+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.51-1+rpt3 (2024-10-08) aarch64 GNU/Linux
WOW! The install overwrites your `/boot/config.txt`!
i’m sorry, but is that bad?
practice or something of that sort?
It also looks like it assumes that you have the framebuffer devices configured correctly
i think that we will need to directly input which LCD model we are using
it’s due to that
Oh yes! That is really bad practice.
Imagine I have a config.txt setup just the way I like it, then I install this. It just wipes out my config without taking any form of backup that I can see
oh damn,
Okay that’s bad
either we backup or run the install script that beginning
It does the same with your `/etc/rc.local`
Which display do you have – the HDMI LCD, the DSI LCD or the Touchscreen LCD?
3.5” RPi Display(MPI3501)
oh,
seems like someone else is maintaining this repo outside of waveshare
