AM335x EDMA Costant Addressing Mode

Takahiro Ogo

Hi

I know the EDMA supports two addressing modes. It is constant addressing (SAM or DAM=1) and increment addressing Mode (SAM and DAM=0)

On the AM335x, Is constant addressing mode supported by all peripheral or internal memory.?

Best Regards,

Takao,

I believe constant addressing mode is a EDMA feature and I think it should work for all peripherals.

Hi Renjith,

Does your statement also apply to GPMC?

Isak,

Yes, it should. NAND/Ethernet driver works like that using GPMC.
