This driver could be useful for many eCos developers who need to add ethernet to an existing hardware design. I note that Microchip offers a daughter board which includes the (similar) ENC624J600 and should make it easy for others to start experimenting with these parts: http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en543132 Are you intending to use lwIP or the FreeBSD TCP/IP stack in your project? Regardless, I would encourage you to verify correct operation with Simon Kallweit's port of lwIP 1.3.1: http://download.westlicht.ch/ lwIP is a good fit for eCos and I hope lwIP 1.3.1 will be integrated in eCos CVS soon. At some point, you will need to complete the FSF copyright assignment paperwork. All contributors to your driver will need to make a copyright assignment. I would recommend getting this sorted out early to avoid delays when the driver is ready. Full instructions are available at: http://ecos.sourceware.org/assign.html Finally, if you are able to collaborate with the wider eCos community on this project, we can add it to the list of registered projects.
