Changing the display in kernel only

I am trying to get a 7.0" Newhaven display to work with the Nano PC T3 Plus and I can't get it to work with the timing changes made to uImage.

I have also made the changes to u-boot but I can't update this on the device for some reason.

Is there an easy way to create an SD card to flash to the emmc that includes the new u-boot and the new uImage? The new uImage I can do as part of the Android build or I can also change this from ADB.

I suspect that both u-boot and the kernel settings must match for the LCD to work. I was under the impression that I only need to modify the kernel for this to work but it seems not to be the case.

As I had suspected, you need to modify u-boot to set your LCD timing. Then you make the same settings in the kernel.
