PCMCIA

[Gerhard TAEUBL]

Hi!

Well this issue we discussed with our project developer...
They want to use 2 Ethernetports for a double ethernet network, for saftey issues. We know, that we never get the full 100MBit on a MPC860 however, the point is, that our hardware don't get much data, but other components (PCs) in the network needs this bandwidth. Beside this to use a SCC for Ethernet we need an hardware redesign with a lot of software adaptions....

We have only one PCMCIA Port realised in HW.

So the (your) DENX Kernel (2.4.4) has PCMCIA support implemented yet? So this is maybe a reason for us to switch over.. (Uhuhu I hope this will not too much work to adapt the configuration again.... :-)

So do you have a list which Ethernet cards work? Or is it only the Xircom card that works?

Why do you think you need a second 100MBit interface? The performance
of  a  MPC8xx  is  a  bit  limited,  so  don't  expect  too  much  of
throughput...

Probably a 10 Mbps interface on a SCC would be the easier solution.

I cannot speak about MV's 2.4.2 kernel, except that it's  pretty  old
and  I  doubt  it  has  full PCMCIA support. But the MPC860T supports
_two_ PCMCIA slots.

You will not get any guarantees. Try it out. The (few!) network cards
we tested so far worked fine.

Best regards,
