Re: I2C and GPS
With the i2c devices removed, I get TTFF of around 1 minute in shr-core. It sounds like putting ferrite beads on SDA and SCL might help reduce EMI, so I will try that when I get a chance.

Re: I2C and GPS
Hi, Ferrite beads aid with removing VHF-SHF feedback and/or uncontrolled oscillation mainly. I cannot see why they would be of use on a (500khz?) I2C bus. At that frequency they would have minimal effect.

Re: I2C and GPS
Hi You can try to add a series resistor to the signals or reducing the drive strength of the driver. The frequency of the signals are not that important but rather the rise time. This is usually not a problem om i2c but who knows. On 24/11/2011, at 14.17, Dave dave...@gmail.com wrote: Hi, Ferrite beads aid with removing VHF-SHF feedback and/or uncontrolled oscillation mainly.

what do I install now?
Hello, I'm thinking in a fresh install of my FR GTA02 (at the moment Om2008.9); what I would need at least are: - GPS OpenstreetMap (tango) - TCP over USB and SSH into the FR - Terminal with Stardict - PIM, SMS, call - X11vnc server Any recommendation for a distribution I should install? Btw: I own another GTA02 with Android installed on. I feel that it reacts much faster on the screen while moving around through the applications or menus. How they do this, as well with X11?

I have been using SHR or over a year with all that stuff. Aside from some implementation problems with the settings dialog, it works fine.
