Hi,
I am working on a Yocto-based distro where I want to interface Pi 5 with Waveshare DSI 4.3 inch display. (Rev 2.1)
Unfortunately, so far wasn't able to get past the following backlight problem and somehow i2c controller looks timed out when I plug the module in:
It seems based on logs that at least DSI panel is recognized but this backlight is the issue.
Here is how my config looks:
Here is the output of raspinfo (some of it):
I am compiling raspberrypi kernel 6.1.77 from rpi-6.1.y branch where the last commits is with hash afd5f659b0453e4c710ce5cf74c577563ff16239.
Here is the output from i2cdetect -y 4 where DSI1 i2c should be:
Here are some extra kernel config options I am enabling:
Here is output from xrandr:
Since I dont have much Pi 5 specific knowledge I wanted to ask about you guys' opinions. What do you think the problem might be? I didn't try this in the default Raspbian OS but Waveshare website says it works with Pi 5.
It could also help if there is anybody who confirmed this module is working with Pi 5 official OS to post "cat /proc/config.gz | gunzip" and "uname -a" so that I can tailor the distro according to those information.
Any help is appreciated, Thanks

Any help is appreciated, Thanks
