You actually have two problems here. First, there is no PCMCIA driver for
the EDB7xxx. This shouldn't be too hard to write. There are a couple of
examples - just look in ${ECOS_REPOSITORY}/devs/pcmcia
The second problem will be to write the WaveLAN driver. I'd suggest that
you use the Linux driver for reference, but start from a similar device.
The only PCMCIA (actually Compact Flash, but it's really the same) network
driver we have is for the Socket LP-Ethernet. Look in .../devs/eth/cf
Give it a look. I'll be glad to answer any questions you might have.
Note: I'd probably do this in two steps. First by doing the PCMCIA driver
and testing it with the known working card. Then write the network driver
for the card you have.
