Like to understand when can the reg_target_address be changed when sending data from the DDR3 to the PCIe bus? The reason being i need to transfer more than 256MB data to the PCIe bus using the IATU, to be able to do that i need to change the reg_target_address. Can we change it on the fly or have to wait until it completes all the transfers? If that is the case how can we know when all the transfers are done?
So if i am using the EDMA engine to transfer 4K of data from DDR3 to PCIe SS1 address 0x20000000 and have the IATU enabled. I assume once the EDMA is completed i can change the reg_target_address to a different PCIe bus address and start the EDMA the next clock? If that is the case then it sounds like the address translation is done on the fly.
Which OS are you using?
