I am trying to connect my BPI M3 (using Ubuntu 16.04) with a display using the MIPI DSI interface.
Therefore I am searching the kernel modules for MIPI DSI, but I dont find anything.
When I run lsmod in my terminal I only get the loaded modules and there is for example MIPI CSI but no DSI. If I look to all .ko files I can not find any files for DSI.
Even Google can not help me.
Does anyone know, where to find these kernel modules on bpi or somewhere in online?
Help please
I opened uEnv.txt, but there wasnt anywhere something like “touch”
But I found both modules at /kernel/drivers/input/touchscreen/… So I guess their are not loaded yet? Anyway I found out, that these are only driver for a touchscreen and not specific for MIPI DSI but used for MIPI DSI?
I also found disp in builtin.
There is a path “/disp2” with disp.ko and hdmi.ko.
But I would expect a dsi.ko if there is also a hdmi.ko.
Are you sure, that MIPI DSI is included in disp.ko?
I tried it manually with “cd” and I can navigator until I reach:
pi@bpi-iot-ros-ai:/lib/modules/3.4.39-BPI-M3-Kernel/kernel/drivers/video
but there is no direktory “sunxi” just “backlight” and “fbtft”.
I also tried to see it with
cat /lib/modules/$(uname -r)/modules.builtin | more
But this way I can also just see two path:
drivers/video/sunxi/disp2/disp/disp.ko
and
drivers/video/sunxi/disp2/hdmi/hdmi.ko
