Dear I.K.,

Yes, the issue had been solved.

The root cause is the clock source from CPU, is not relative to our chip.

Thank you very much.

Hi CK Ho,

I'm glad to see you resolved the issue. For future reference, do you mind specifying exactly what the issue with the clock source from the CPU was?

Dear I.K.,

The clock frequency is incorrect.

After doubling the CPU clock rate, the panel can be displayed well.
