Does that mean that I > have ported eCos on the hardware? I presume by test programs you mean the normal eCos test programs. Have you run them all? If they all pass then yes, you have made a port.

Using the Linux driver is probably the wrong solution. The TCP/IP stack in eCos is a port of the FreeBSD stack. You will find it easier to use the FreeBSD wlan drivers than a Linux driver. You should also be aware that its not just as simple as porting a driver. 802.11 has its own protocol stack which goes between TCP/IP and the hardware driver. You will need to port this stack as well. It will be complicated by the fact that eCos's port of the FreeBSD stack is quite old. You might find you need to update the TCP/IP port before you can put in the WLAN stack.
