i.MX53 Frame Synchronization Flow debugging

[torus1000]

Hello chip experts,

Now I'm debugging my code for IPU IDMAC ch23.

In spite of following the Frame Synchronization Flow described in p2777 of i.MX53 RM,

IDMAC buffer toggling didn't observed when double buffer page flipping was used.
Please see step 4 on p2777.

Is there any tips or secrets to activate it?

How can I debug it? Which status registers should I check first?

Thanks.

HI torus1000

I am not aware of such tips, probably one can look

at IPU examples in On-Board Diagnostic Suit for the i.MX53 Quick Start Board

or i.MX 6Series Platform SDK

Best regards

igor

Dear Igor

Thank you for replying.

Finally I found my mistake which lost complete flag by read-modify-write access to the SET/CLEAR registers.

Have a nice day!
