Field Documentation

◆ mappedFlowGrp

uint32_t Udma_FlowAllocMappedPrms::mappedFlowGrp

The Mapped flow group to use when channel type is UDMA_CH_TYPE_RX_MAPPED.

The driver will allocate mapped flows from this group. Refer Udma_MappedRxGrpSoc macro for details about mapped RX flow groups.

◆ mappedChNum

uint32_t Udma_FlowAllocMappedPrms::mappedChNum

The assigned mapped channel number when channel type is UDMA_CH_TYPE_RX_MAPPED.

This is used to allocate the corresponding mapped flow for the particular channel. The driver will allocate from the mapped flows which are dedicated for this particular channel.
