Hi,

I am working on a project, in which I want to copy a data from SD card (on SSP0) to  a USB flash drive, I want to reduce the time span required to copy data from SD card to USB drive,so  I decided to use a DMA. No such provision to access the DMA, to copy data from SD card to USB directly , I must first need to copy few bytes in memory buffer, then transfer that bytes from memory buffer to USB drive repeatedly to copy 8GB. I also explore the sample DMA example in code bundle LPC23xx-24xx Sample Software. Can you suggest a simpler way to accomplish this DMA transfer. It will be more helpful if you could provide a other code example
