On a somewhat different note regarding the DM355. Did you have to take any special steps to get the onboard Ethernet working properly? We have DM6446 boards that we used for development and have a project going with them (and our own custom boards). Both are functioning without any major issues however when we try to boot the kernel on the dm355 the Ethernet port always comes up with 'no link' I seem to recall just being able to plug in a cable and 'ping' the eval boards. Is there an initial step that we've missed? Thanks. I can attach a clip from our dmesg output when I get only my development box if it'll help at all.

Does this mean the DM355 does not have an on-chip MAC and that it requires an external MAC/PHY chip? If I wanted to create a DM355 solution with two ethernet interfaces such as LAN and WAN, would I need to write special drivers or require major board changes? The MAC/PHY is external - it is attached to the AEMIF bus. To implement another ethernet interface you need to modify the CPLD code to add an additional chip select and modify drivers for the address space change. > > This seems more complex than I anticipated.

Another alternative, if the changes that Steve suggests are more than you want to do, would be to make a second network device available via the USB port. We've used a USB to ethernet dongle for debugging our 355 based board, and it works fine. A third option could be to use an ethernet card for the SDIO (SD/MMC) slot. I don't know if there are cards available for wired ethernet, but we are using a wireless (802.11a/b/g) card from CardAccess. _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
