How to do a SPI to SPI transfer

I want to transfer data from an external flash on SPI-2 to a different device on SPI-1. The motivation is to avoid chunking the data using on-chip RAM, and to shorten the transfer time. Is this possible? If so, how? My processor is a K64.

Hi Jeff,

I think this is possible. You can use EDMA to move data. But the SDK driver doesn't support that. It only support DSPI_MasterTransferEDMA or kEDMA_MemoryToPeripheral. So, you have to do it by yourself.

Jing
