I couldn't read it because it was in Chinese.
It is not made by an individual.
Can I do it alone?
Or should I get help from an NXP engineer?
Actually, I'm trying to port LVGL to i.MX6ULL, but it's not easy.
Below is the error log.
I think the dependency is making the error.
(LVGL conflicts with other modules or LVGL requires another module)
