MPC5200 PCI questions

MPC5200 PCI questions

[Iñigo Lopez Barranco]

Hi.
Is it possible, with the present version of BestComm, to use DMA for IDE and PCI at the same time?
As is not possible to use IDE DMA and the integrated FEC at this moment, I'm thinking of using the integrated ATA controller in the MPC5200 with DMA for an IDE disk and the PCI controller to interface to a PCI to ethernet transceiver in a custom board. Is this possible? Any recommended transceiver to use with linux and the MPC5200?.
Also, I would like to know if there is a known to work PCI ethernet card (10/100 if possible) for use with the Lite5200 kit, supported by linux.
Thanks in advance.

Iñigo

Yes. We've been testing for example with an EEPRO100 network card  to
avoid the known conflicts with the FEC.

Yes, this should work. We use the EEPRO100 a lot.

Most cards should work just fine.

Best regards,

I don't really know how PCI DMA works in linux ? Is there generic hook
that must be implemented somewhere in the kernel and then are called
by all the drivers ?

I've just plugged a intel eepro100, and it's recognized. I can also
ping & telnet & ftp small files, but it freeze ( just the transfer )
for larger files ... Since I have the same behavior in the bootloader,
that may be a hardware issue ...
