Hi team,

When detect CRC error, screen is flicker and the value of 0x0A also change.

How to deal with this issue?

Hello Amelie,

CRC errors are back channel errors. This means the link quality is not optimal. You need to improve the quality of your link to eliminate CRC errors.

It seems that the back channel communication is not optimal.

Is it need to change hardware to optimize it? Any other software could opimize?

Thanks!

Yes, this needs normally link quality improvements, i.e. Cable/ Connector/ PCB layout ... etc

No software change can improve this.
