Hi,
my customer has some questions about descriptor in VIP on AM5716. They want to check if the Descriptor is loaded or completed.
1. Should we use the Outbound Data Transfer Descriptor to transfer data from VPDMA to DDR3?
2. Is the bit[23:16] LISTx_BUSY bit (Read Only) in VIP_LIST_STAT_SYNC register (0x4897 D00C) correct for checking the Descriptor status? And, does each bit mean 1 = Descriptor is loaded, 0 = Descriptor is completed?
3. There is the bit[9] RDY bit in VIP_LIST_ATTR register (0x4897 D008). Does the bit mean 1 = Descriptor is loaded, 0 = Descriptor is completed?
Best Regards,
M.Ohhashi
