Hi!
I’m having trouble porting a working MIPI DTS code from EdgeV to VIM3L (both using ubuntu desktop).
Have tried every parameter in the dts with no success…
please see the attached image where I ran the cube example in /usr/share/arm/opengles_20/cube
Same MIPI init, and sync parameters but the image gets completely broken
I need help ASAP for a demo, thank you! @numbqq @Frank @Gouwa @RDFTKV
Why you need to port? The MIPI is already supported for VIM3L.
I’m not porting the driver, I’m “porting” the dts parameters… that’s what I meant… SAME parameters, but it does not work on VIM3L.
What LCD? Khadas TS050 or your own LCD?
Own lcd… the parameters and code are the same in edgev and vim3l dts, it should work the same
Maybe not. There maybe some little difference.
What’s the resolution of you LCD? Can you share your LCD configuration?
@quatro Can you apply this patch to u-boot and try again?

After update u-boot, you need to revert the u-boot env:
kvim3l#env default -a
kvim3l#saveenv
kvim3l#reset
I have applied the patch, and rebuild the image, how do I run:
?
Thanks!
If you rebuild the whole image, you don’t need to do this. Just burn the new image you buuild.
perfect… it is building right now… is there any way to just update the uboot part?
Yes,
$ make uboot
$ make uboot-deb
You will get the u-boot debian package in: build/images/debs/0.8.2/VIM3L/linux-u-boot-vim3l-vendor_0.8.2-2015.01_arm64.deb
Copy it to the borad and install it:
$ sudo dpkg -i linux-u-boot-vim3l-vendor_0.8.2-2015.01_arm64.deb
$ sync
$ sudo reboot
perfect! apparently I’m on version 0.7
Just for reference, you can find the package in your own folder.
Installed deb, sync and rebooted… but it is still showing the same glitch
Can you show the result of fw_printenv command ?
