Just some really stupid questions:

This is with a 4xx core, right? Is this the same SPI controller design
like in AMCC's 40x and 44x cores, i. e. with a "FIFO" of depth 1?

Assuming you're running your SPI clock at 1 MHz,  you  get  one  data
byte  and  thus  one interrupt at a rate of 125 kHz. I doubt your CPU
can handle such a load?


Best regards,

Wolfgang Denk

A witty saying proves nothing, but saying  something  pointless  gets
people's attention.
