Linux/AM3359: GPMC communication with an external FPGA with two Chip Selects

Part Number:AM3359

Tool/software: Linux

Hello,

Please clarify the following doubts regarding GPMC communication with an external FPGA.

16 bit GPMC asynchronous mode is interfaced with FPGA using CS3 for normal data transfer & CS5 for DMA operation

1) If am transmitting 256kbytes over CS5 and at the same time I am operating CS3 for single write/read. How would be the behavior of GPMC. whether it will stop the DMA operation and start CS3 single write / read or immediately stop the DMA operation over CS5 ?

2) If am using 3 Chip selects. How would be the priority of data transfer operation over these chip selects ?

Waiting for your reply

thanks
