Hi guys
Im trying to set up zynthian on rpi 4b with a waveshare 4.3" dsi lcd and can’t get it to work. Can anyone help me please?

Thanks in advance

Here’s the wiki of the display;

In webconf navigate to Hardware->Kit and select “Custom”.
In webconf navigate to Hardware->Display and select “Pi 7 Touchscreen Display 800x480”. You will need to disable

Looks like similar display so this could work.

Hi, you have to configure it in the webconf. Choose custom config and set /dev/fb0 for the frambuffer

Except height and width, you shouln’t needs something more
[Edit] After having a look at the wiki maybe you’ll have to set thé dt-overlay too [/edit]

I’ve got one DSI display from aliexpress like this (really nice except, there is no mounting holes for fixing it in a case):

I didn’t needed to set anything to get the touchscreen to work.
Maybe yours need a specific touch driver

Got it working. Changed the wiring to dummies and now its working. Changing the size of the font was helpful too. Now i have to figure out how to set up my audio interface without breaking jack.
Have a roland rubix 24

I didn’t knew that interface before, looks good. If it’s USB-midi class compliant (like most of the USB sound card) it should work as is, just select in the webconf a “generic USB device”.
I could suggest, as it has an external USB type C power input, to use that feature to prevent you from some underpower problems like Xruns.
