Dear All,

 

Hello. I have a question about double buffer of IPU in i.MX6DQ.

My customer's system will display with double buffer mode in Non-OS program.

And, they tested the display with double buffer mode after the initialization of IPU.

 

[Result]

Use the Buffer0 earlier : Success

Uses the Buffer1 earlier : Looks flickering

 

[Question]

When one enable the Double Buffer in IPUx_CH_DB_MODE_SEL0,

Is there limitation on the 1st display?

Ex) First time, it is necessary to use from the side of Buffer0.

 

Best Regards,

Keita
