I think you're missing something here. We use the DMA engine in memcpy mode (SRAM -> DRAM), not in device mode (dev -> DRAM or DRAM -> dev). So there's no dmas prop defined in the DT and there should not be. Regards, Boris
Ok, so the memcpy SRAM <-> DRAM will hog the transfer between DRAM and LCD if my understanding is correct. That's the DMA that Peter wants to disable with his patch ?
Then we can then try to force NFC SRAM DMA channels to use just DDR port 1 or 2 for memcpy ?
I have also received a suggestion to try to increase the porches in LCDC_LCDCFG3 .
