Hi,
I want to DMA data from GPIO to SDRAM, but when I read the UM10503 Rev. 1.9 — 18 February 2015 page 20 fig 3, there is no DMA connnection between GPDMA and EMC . But in page 40 , fig 11 show connection between DMA and EMC. So , can I do that ?
All I want to do is :
1. DMA data from memory to GPIO to generate some waveform
2. DMA data from GPIO to SDRAM to get data back to system
3. DMA data from SDRAM to USB0 to transfer data to PC
Thanks
Max
