RE: memory problems on ppc 8260 based hardware

See
http://e-www.motorola.com/files/32bit/doc/white_paper/MPC826XSDRAMWP.pdf

Basically the clocks going to the SDRAM has to be leading the clock
going to the 8260 by about 1 ns.

This will only show up when doing burst accesses (like linux does all
the time) and no while doing standard memory tests.

Hi,
      Mr Torgersen, thanks a lot .
      I have read the Errata of 8260.  SDRAM is 32bit    (60x
bus), is it the reason?  could you say something about you
fixed the hardware on an inhouse board?

Best regards!
 liu
