i.MX53 Frame Synchronization Flow debugging

torus1000 — Wed, 17 Jun 2015 03:41:22 GMT

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.

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!
