I’m trying to get a display working on a iMX8 but I’m actually stuck.
First I have a pre-release Verdin iMX8MM (V1.0B) and would like to know if it is possible to get it working with this board, We are currently buying the current release (V1.1A) but still didn’t received it yet.
I’m working with Yocto, Currently building tdx-reference-multimedia-image on 5.0.0-devel-202010 tag (because newer release have dropped support of this pre-release board).
Scanning for I2C Chip give me slave 48, 49, 4a, 4b and 50 when DSI to HDMI card is plugged. the address 50 is used by a driver (seems to be an eeprom driver) while 48 to 4b seems not used by kernel. Hardware seems to works fine.
Unplugging the screen doesn’t raise anything in the kernel.
Is there something to load in order to activate this output ? Or something to configure in the Yocto image perhaps ?
I could build TDX Wayland with XWayland 5.1.0-devel-20210319081341+build.0 (dunfell) verdin-imx8mm (timestamp seem to be my compilation date), but still no output on screen (DSI to HDMI board).
Anything I could check ? Or maybe better wait for the new card.
I would add that I tried the screen on a computer and it works fine.
Latest Edit :
From the Tezi recovery I could install the build.4 and I have now a working screen. I’m now wondering with wich exact commit this image has been built? (I inited my repo with repo init -b refs/tags/5.1.0-devel-202011 -m tdxref/default.xml and it didn’t works, or I missed something)
