Hi, I'm having some issues with my verdex / wifi-stix / robostix. I have two power suppies, one feeding the robostix, and one for the wifi-stix to ensure adequate power is available, as has been suggested in many posts to this list. What seems to happen for me though is that I can have the boards plugged in together (i.e. wifi-stix -> verdex -> robostix), and flick the power switch (using power board so power is applied to both supplies at the same time) sometimes everything boots up ok, and the wifi-stix lights come on (ethernet and wireless) and the loaded robostix program starts (blinks red light - from i2c-io.hex). Other times when I turn it on, it seems as if the boot has failed as only green robostix LED is on, and the wifi-stix orange d2 LED is on. Another thing to add is that when i break the setup into two (i.e. wifi and verdex as one, and robostix as the other) both start ok (relevant LED's come to life as described above). Can anyone help me with this? Its proving to be quite a roadblock! Cheers, Ross. |

You probably want to do the mod suggested here (connecting V_ROBOBATT to V_BATT), then you can use just the one adapter. <http://pubs.gumstix.org/documents/robostix_power.pdf> -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

Thanks Dave, I did the mod quickly, and it does simplify my setup somewhat, thanks for that. I'm still having issues with it not booting properly sometimes though...Any ideas?

I've looked at http://pubs.gumstix.org/documents/robostix_power.pdf, and I'd like to perform the mod, but I'm not sure exactly how to do what is described there. This is probably a warning sign that I shouldn't do it, but I'd like to try because it eliminates the need for two power supplies. Is there better documentation on how to perform the mod (e.g., pictures, steps, etc)? Or, in lieu of better documentation, is there a good way to read the instructions at http://pubs.gumstix.org/documents/robostix_power.pdf? Clearly I am not a hardware person, but I'd like to learn, and I'd like to be able to sort this.

So, looking at the robostix_power.pdf, it looks like I can either connect the two leads listed in detail 1 (which permanently mods the board -- if I'm interpreting it correctly), or I can connect the pin on vboard with the second uart (listed in detail 2 -- this I can do with a wire and two crimped leads if I'm interpreting it correctly). My guess is I want to do the connection in detail 2?

Hello, I've not even hit this point, but I'm interested to see what comes out. I have a verdex + netwifimicrosd, and they're working like a charm. I've been able to program the robostix on it's own without a problem (I've modified the Simple-Servo-2 and have the lights flashing and two hs-311 swinging back and forth on my desk). I've now flashed the i2c-bootloader onto the robostix, and on it's own it appears to behave nominally (red flashing led twice a second). If I connect the robostix to the verdex with the netwifimicrosd (and power through the robostix), I see the same behavior described below: the netwifi d2 lights up, but it appears nothing else happens. I'm guessing I need to power the netwifi with a second power supply. So I guess my question is, if the netwifi d2 lights up, but things go no further (green light on the rj45, then blue d1 blinks), does that mean there's not enough power for the netwifi card? I've looked around quite a bit but there doesn't appear to be general FAQ on physical signs that things are going ok, and what to look for when things aren't working and what that means. I realize this is all very vague ... and I appreciate all the feedback this forum provides ... Ross McDermott wrote: > > Hi, > > I'm having some issues with my verdex / wifi-stix / robostix.

That would be a good non-permanent solution. Soldering the pins in detail 1 really requires good soldering skills since the pins are really small. You can also do a permanent job with detail 2, by soldering a small wire between the same two pins on the back of the board. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

Hot dog! That worked. I've got the i2c-bootloader running on a robostix, connected to my verdex + netwifimicrosd, and they're all talking!

Hi Dave, Im using the standard gumstix provided power adaptor, and using buildroot not OE. Also not using any touchscreen stuff. I always seem to have bad luck with hardware!!! I think i'll have to make the tweener mod to see whats happening with the verdex / robostix, as with just those two connected the robostix does not seem to pulse the robostix to allow the program to start (i have script on startup that should be doing that)... If i make the tweener modification, can i still use it with just the verdex, or will it HAVE to be connected to robostix as well (twiki didnt seem to be too specific on that point). Cheers, Ross.
