Unfortunately I missed the announcement at http://www.gumstix.net/Hardware/cat/Known-issues/112.html#faq182 by a few days and ordered an Overo Fire and Tobi 2392. Can I fix the problem myself by removing IC5 from the Tobi PCB, if I don't mind losing USB Host functionality ? Or are there mechanical conflicts between other components ? Pascal |

I think you will find that the offending chip in question is for WIFI functionality. If you remove it and lose WIFI then it kind of makes the point of buying a Fire not worth it.

I am talking about IC5 on sheet #3 of http://pubs.gumstix.com/boards/TOBI/PCB30002-R2392/PCB30002.sch which seems to be dedicated to controlling USBH_VBUS. It obviously conflicts with C59 of the Fire (PF3503-R2277). Maybe there are other, more subtle conflicts (possibly involving wifi components on the Fire PCB), but I haven't noticed them yet. Pascal |

Okay, sorry I got confused with another board. You are right about the Tobi. On 5/19/09, pa...@pa... <pa...@pa...> wrote: > R. P.

For the record: After removing IC5 I was able to plug the Overo Fire into the Tobi and use ethernet. I thought the boards were slightly bent because of a capacitor of the Overo hitting the DVI chip underneath, so I removed it as well, but this turned out to be useless. Pascal |
