I want to detect and reinitialize the spi communication if it fails. I mean the communication may seem to continue but it may loss the synchronization with a peripheral device and it may read nonrelevant datas or it may halt. What do you do or what can we do in order to detect those situations and reinitialize and restart the communication.
SPI protocol itself doesn't have provisions for error detection. But if the structure of the data, which the SPI slave is sending, allows to detect the loss of synchronization you're describing, or other faults, then it's possible to achieve what you're trying to do. What is the peripheral?
SPI has the select signal as sufficient synchronization means. There are SPI-like protocols, that access a single slave without SYNC/CS, they need additional methods, e.g. timeout to reset the communications to a known state.
Because SPI is basically intended for board level data exchange, it doesn't consider hardware transmission errors and doesn't provide an integrity check at the physical layer.
