Re: MPC 8xx as SPI slave...

Dear Wolfgang Denk,

  Thanks for your reply...

This could be a cache issue. Which source is your SPI driver based on?

  Also, I was doubt the cache problem.
  I'll  check again...
  My code is based on your lwmon_spi.c just basic function.

Does the 8xx transfer data at all? You know, SPI has a very, very low
priority onthe CPM, so it will be starved  by  any  other  I/O  (like
ethernet and especially USB).

  Just transmit the previous data of TX BD not on time.
  I'll check the priority...


  Thanks!

Best Regards
Young-Han, Kim
