Where to find DSI1 driver for manta m8p v2

General Discussion

Basic Information:

Printer Model: Voron 2.4 R2 350mm
MCU / Printerboard: BBT Manta M8P V2 with CM4 module
Host / SBC
klippy.log

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

Wanted to install new touchscreen display to use with Klipper screen

Display model [ BTT PI TFT43]

In order to use this display via DSI interface BTT Manta M8P V2 DSI drivers need to be installed

but the issue is that the repository to download set drivers is not longer hosted.

{https://datasheets.raspberrypi.com/cmio/dt-blob-disp1-cam1.bin}

I’ve been searching for info on alternative ways to install drives but no luck, if anyone can point me in the right direction

I think you have to enable the DSI overlay in the file armbianEnv.txt.

Read here:
How to use TFT PI on DSI with CB2 · Issue #32 · bigtreetech/Manta-M4P

And here: Snippets of Nifty • DSI Display on a Manta M8P

I have this type of TFT installed on one of my printers but can’t access the config right now.

Unfortunately both methods will not work, Im runnning on CM4 and not CB2 and also raspberry has discontinued support for the following

sudo wget https://datasheets.raspberrypi.com/cmio/dt-blob-disp1-only.bin -O /boot/firmware/dt-blob.bin

basically ill get a 404 error stating that is no longer available to download

Ok, that is bad.

At the very end of this thread the file is attached: dt-blob.bin still needed for CM4S? - Raspberry Pi Forums
I can’t guarantee this is safe but might be worth a try.

You could try the files from this Waveshare archive ; the link is at the end of the page, under “Demo” : “Source files and demos”. (Waveshare is an official reseller for Raspi’s)

Recently had this issue with two MBs (Manta 5P and Manta 8P), CM4 Lite Compute Modules (not ‘S’), and Waveshare 4.3" DSI touchscreens. Struggled a bit !

The Raspi Foundation removed the drivers ; moreover, the documented command line does not display any error message (404 or whatever) !

I simply copy dt-blob.bin to /boot/ ; the root directory on the FAT partition.

[EDIT] I didn’t remember where the file I’m using came from. Found it ! It came from the Wayback Machine. It is a bit more recent than the file from the Waveshare archive. See here : DSI display and CSI camera with CM4 · Issue #152 · bigtreetech/Manta-M8P · GitHub

Thanks… that did the trick
