SPI communication with DMA handler

[RBV]

Hi, I have implemented SPI communication using DMA and it works.

When i receive different data than the mentioned protocol format then it hangs and i dont receive any more data and i have to reset the chip to get back the communication.

Is there anyway to overcome this, any thoughts about the DMA handling??.

Write your code such that it's robust against unknown data coming in and implement verification on incoming data.
