Which module is in charge of generating the write image address? SDMA or MMDC? Can either of this module generate 2D address which line offset exists between image lines?</P></BODY></HTML> Thu, 22 Jan 2015 02:11:54 GMT samxiao 2015-01-22T02:11:54Z Controlling the Write Address When Writing Image to External Memory https://community.nxp.com/t5/i-MX-Processors/Controlling-the-Write-Address-When-Writing-Image-to-External/m-p/367043#M52205 <HTML><HEAD></HEAD><BODY><P>I have questions about controlling the address of i.MX6 dual lite (the one with EPDC controller in it) when writing an image of 1600x2400 to external memory.
