Hi community,


I have a question about i.MX6Q IPU.

Please see Figure 37-22 in IMX6DQRM Rev.1.

According to this figure, SMFC has 4 DMA channels.

And SMFC seems that it can use multiple channels to transfer data input from MIPI-CSI.

Then, how about in the case input from parallel camera?

Can SMFC use only one DMA channel to transfer if data is input from a parallel camera?

Or can it use multiple DMA channels?



Best Regards,
