AM335x - DMA Cross bar event

Hi

We are trying to configure MMC slot 2 (the third MMC instance) to use with an SDIO wifi interface card.


It looks like to properly configure the DMA to work with this, the channels have to be configured for what the datasheet suggests 'cross bar' events.

Could anybody please give some pointers on how to achieve this? Our platform is WinCE 7, but any general pointers would be useful as well even if they are not specific to WinCE platform.


Thanks,

Samie
