Hi,

I'm trying to send/receive data using SPI-1. My use case involves sending and receiving continuous data but it seems that SPI controller is frequently missing one or more bytes. Further more, I get random garbage data bytes after around 10 transfers (8 bits each).

I've downloaded the sample codes from the following location. The my SPI driver is doing read/writes exactly the same way.

Here's a little about my driver configuration.

* Using Fixed Peripheral Select (SPI_MR[PS] = 0).
* Chip select register 0 (SPI_CSR0).
* Master Mode.
* 8 bit transfer size.

There's nothing mentioned in the Errata for this scenario, the same driver works okay with AT91SAM9263. Any pointers are much appreciated.

Thanks!

continuing my earlier post....

Its an interesting observation that the data byte missed is actually copied to SPI_RDR (Receive data register).

So basically when I write data in SPI_TDR, it either gets transferred to the slave (which is correct) or it gets transferred to SPI_RDR (incorrect).

Any pointers/thoughts?

Thanks!
