Sorry - I don't know either - although I'm pretty sure it's been discussed. I did some poking around and it appears to be set in the conf/machine/include/gumstix.inc There's a line that says: PREFERRED_VERSION_gumstix-kernel = "2.6.21" > Also whenever I bitbake recipes, i.e. helloworld or something to read the > imu, it works but says "completed 229 of which 216 tasks didn't need to be > rerun" and it appears to start at task 174.

I think if you have dependencies, then this means that the dependencies are already built so it just skips them. > Sertest appears to work but I have only really tested it using a loop back. > I also used another computer running putty but that had mixed results, i.e. > I could send characters but I wasn't able to receive any. That sounds very much like a grounding problem. loopback doesn't need any grounds, but connecting to another computer does. You should be able to connect the level shifter to the PC, with just power and ground coming from the robostix, and then loop back the logic level side of the level shifter. -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ |
