Hello,

I designed a custom board that is a sort of sound recorder.

It takes some audio data and is supposed to write it to an external nand flash and access the data via USB connection to PC.

I have a couple of questions.

1. Can i interface the nand flash simply by using an SPI interface on the controller  ? If yes, is there an example in the sdk i might use ?

2. Do i need to format the nand flash to a common filesystem such as FAT ? And if so is there an example in the sdk ?

3. I presume i must implement a mass storage emulator on my controller so i may access the data on my nand flash , is there an example in the sdk i might use ?

4. What is different in  DSPI(DMA SPI)  as compared to standard SPI ?
