Waveshare LCD Driver Issue on Raspberry Pi 4

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

  1. ming_58391#0000

    What was your setup when it worked and what have you changed?

  2. melta101#0000

    did a fresh raspian OS install

  3. melta101#0000

    honestly, i dont remember what i did to get it to work

  4. ming_58391#0000

    We have all been there!

  5. melta101#0000

    thought it was the last, i would care about it since it worked

  6. melta101#0000

    smh

  7. ming_58391#0000

    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

  8. melta101#0000

    should be ~6.6 if i remember

  9. ming_58391#0000

    `uname -a`

  10. ming_58391#0000

    (Assuming you have shell access)

  11. melta101#0000

    gimme a sec

  12. melta101#0000

    Linux pi 6.6.51+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.51-1+rpt3 (2024-10-08) aarch64 GNU/Linux

  13. ming_58391#0000

    WOW! The install overwrites your `/boot/config.txt`!

  14. melta101#0000

    i’m sorry, but is that bad?

  15. melta101#0000

    practice or something of that sort?

  16. ming_58391#0000

    It also looks like it assumes that you have the framebuffer devices configured correctly

  17. melta101#0000

    i think that we will need to directly input which LCD model we are using
    it’s due to that

  18. ming_58391#0000

    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

  19. melta101#0000

    oh damn,
    Okay that’s bad

  20. melta101#0000

    either we backup or run the install script that beginning

  21. ming_58391#0000

    It does the same with your `/etc/rc.local`

  22. ming_58391#0000

    Which display do you have – the HDMI LCD, the DSI LCD or the Touchscreen LCD?

  23. melta101#0000

    3.5” RPi Display(MPI3501)

  24. melta101#0000

    oh,
    seems like someone else is maintaining this repo outside of waveshare
