- ME 09:20 AM Software Development: RE: Can't ping by name
- I think the dns-* options in /etc/network/interfaces require that you have the resolvconf package installed. Do you have it?
- DG 01:51 AM Software Development: RE: Can't ping by name
- Solved! Thank you!
The only disadvatage is the /etc/resolv.conf file is rewritten (by udhcpc?) on reboot.
I wonder the dns-nameserver parameter in the /etc/network/interfaces has no meaning, even for static ip configuration?

- MW 07:30 AM Software Development: RE: Can't ping by name
- We've noticed that the DNS doesn't get updated automatically as well.
If you know your DNS server, as a workaround, add the following entry to /etc/resolv.conf (you may need to create this file if it's not there). - Hello!
Problem is I can't ping any host by name (got "bad address" error), but no problem with ping by IP. I guess it is related to DNS. How can I solve it? (sorry for stupid question, I am nub). Ping to DNS server which I have assigned...

- If you need more or you did not buy the development kit, the part number for the interface is 80-000286LC-1A. If you contact critical link someone should be able to help you get one.

I am using mii-tool to test that mii interface. I have used ths before with no problem, but now I get a linux error status as per the attached file. Any ideas what I have set wrong?

Thanks for that. Now the spi interface works (but not the switch). I now get the following at boot up.

- The JTAG Interface of MityDSP-L138 is different with my XDS510. There is a convert board for it? How can I use the MityDSP-L138 with XDS510.

- MW 07:19 AM Software Development: RE: KSZ8995MA Ethernet Switch Support
- Ok Charlie,
You need to do a little more work on your baseboard file. You need to make sure you strip out all of the stuff that isn't on your host board.
The culprit, I think, is that you are still calling baseboard_setup_mcasp(),... - CK 03:02 AM Software Development: RE: KSZ8995MA Ethernet Switch Support

Can you attach your .config file and the dmesg outputs? The SPI_MAX_CHIPSELECT is a good catch. That needs to be fixed upstream, sometimes those guys get a little nuts trying to save a couple of bytes. The davinci spi ca... - CK 10:35 AM Software Development: RE: KSZ8995MA Ethernet Switch Support

Yes, I have only spotted that today, but when I changed the inputs to 0b10, with some difficulty since they are tiny pins, the unit still does not work. I have missed a few bits out but I suppose that is why we do dev boards.
