I uses Texax Instruments TI Sitara AM387X EVM.
I would like to transfer some data from DDR memory to PCIe device with edma3 controller on the board.
When I measured the payload size of dma transfer, that was 64bytes despite PCIe device can receive 128bytes data.
It seems this is limited to DBS(default burst size) of edma3 controller.
Is there any method to transfer larger size?
