Hello, are you using the latest code? We have made vim3 compatible with multiple different MIPI screens through TP, so you have to check the relevant codes in these paths and modify them to the bootloader/ you need. Use git log --grep=LCD in uboot, system/core, hardware/amlogic/hwcomposer, hardware/interfaces to search for LCD or MIPI related submissions. The phenomenon in the following post should be similar to what you are encountering now. You can refer to it. Our VIM series is handled in this way.
