I have a question about double buffering feature of i.MX53 IPU.
I know the FSU automatically toggles the DMA_CH_CUR_BUF_# to point on the correct buffer(EBA0 or EBA1) to be used by the channel.
However I would like to toggle it manually by using IPU_CH_BUFx_RDYx register when CH0 transfer done followed by IPU SYNC interrupt(IRQ=11) requested.
In such case when actual toggle will happen? It will switch immediately or wait something?
Can anyone help me? I want to confirm it for the safe screenshot feature.
