How to change fame rate pico-wizard-imx8m-mini with 10.1 " panel about cookers HOT 8 CLOSED

Just tweaked a new timing for this panel, looks perfect no matter boot animation or home screen controlling.
Also uploaded the commit already, please do 'repo sync' to update kernel repo there, recompile and try again, should be works!

Don't forget close this ticket if works :)

** Screen not smooth that I mean I see a little bit ripple or vibrating (not sure in pixel or backlight) and more when I increase backlight to maximum.

About this problem, it's a bug which I mention as above, just fixed, please update your kernel repository (/vendor/nxp-opensource/kernel_imx), thanks!

Could you take a video to youtube or provide me the test video file if possible? I have no idea how not smooth.

Try to increase the CMA size of /device/fsl/imx8m/pico-imx8mm/BoardConfig.mk
124 CMASIZE=736M
to
124 CMASIZE=960M

And try again, 1920x1200 resolution could be too heavy loading with high data rate video file, I'll check it later.
Thanks a lot

Also want to know what's your DDR memory size of PICO-IMX8MM? Thanks

Thanks for your reply,

I'm using PICO-IMX8MM 4GB Memory, I just look at the home screen, not sure because of refresh rate or LCD backlight

I'm trying to reproduce issue here, but need check with you again about your display issue:

1. Video play is very good performance.
2. Only boot animation not smoothly because 1920x1200 is maximum limitation of MIPI for PICO-IMX8MM, if you think it's not okay, you take out that animation manually.
3. home screen looks smoothly when I swipe it, but I saw a bit flicking bug on the screen, do you mean this flicking issue ??? I need detail description if possible.

Thanks a lot

Touch screen I found issue too and I have to fix dts file for correct touch screen driver and I will try to build with your fix later.

Now, It's ok if you confirm video can play good performance.

** Screen not smooth that I mean I see a little bit ripple or vibrating (not sure in pixel or backlight) and more when I increase backlight to maximum.

Maybe just problem only my screen hardware, I will buy to try compare later.

Thanks.
