XIO2001 and DM648

Hi, we have a design which used the xio2001 as the pci-pciE bridge between dm648 and dm8168. the clock speed in pci side in xio2001 was set to 33Mhz, the design works fine for a long time, but recently when we build more boards, we found there is lots of chance of unstability happens in this PCI interface between XIO2001 and DM648.  We found the data sent from xio2001 to dm648 doesn't match,  The possibility is not high but does exist!  Do you have such experience in this XIO2001 chip?

Thank you,

JK

你进行了什么动作从而导致数据不匹配，以及不稳定的现象？

Hi Chen

we use the pci interface to boot the dm648 at the beginning, the mismatch happens at that booting stage.  the data is sent from host to dm648 through PCI interface.

Thanks,

JK
