So I'm really excited that I was able to get my gumstix flashed with my new root_fs! The bluetooth is working AND I was able to get the robostix_drv.ko loaded! All problems I have been struggling with! EXCELLENT. Ok the next hurdle: Using gumstix as an ISP I tried to do a make in the buildroot to get the uisp incorporated... I have previoiusly built the g++ stuff... I got an error about g++ not working right... [Sorry I just lost the msg if I get it again I will post it]. I'm hoping another make will fix this. Q- What type of connection do I need between the gumstix and robostix? I currently have: gumstix, robostix, tweener, and a rs232 level converter that plugs into the robostix. How do I connect so that I can use uisp? Can I hook the tweener to the converter and to the port on the robostix? Q- Can I use my desktop to program the robostix? I mean why can't I uisp from the desktop? Seems more practical than the gumstix... Thanks! |

I just followed my own directions, since I need to rebuild my precompiled binaries due to the uclibc incompatability thing. The precompiled binaries should work fine. > Q- What type of connection do I need between the gumstix and robostix?

If you're going to use a tweener with the robostix, you'll need to cut a trace (see http://gumstix.org/tikiwiki/tiki-index.php?page=3DTweener-Mod - you need to cut the trace where the left red line is). If you're connecting your console thru a level shifter to the gumstix connector on the robostix then you don't need the tweener. If you want to use uisp from the gumstix, then you'll need the jumpers, but otherwise no additional connections are required. > Q- Can I use my desktop to program the robostix?

Doing it from the gumstix becomes alot more practical when both are buried in the guts of your robot :) The other option is to program the i2c-Bootloader into the robostix (perhaps using your desktop) and then use i2c-load to download to the robostix. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |
