How to modify PSRAM page size of IMXRT685

[Felix3]

I want to modify IMXRT685  psram page size to 2048. Is there anyway to modify it ?

Thank you

Hi @Felix3 ,

The pSRAM demo doesn't divide memory address line to row and column. All the pSRAM space is row space. You can use the code directly because APS6408 is 1024 byte each row. less than 2048. The DMA size limit to 1024. So, there will not be any problem. You can also change the DMA size to 2048 if you use APS256. But don't bigger than 2048.
