Re: RasPi power usage measurements ~2 watts at idle

Did somebody check how much current is being drawn from the RG1 (1.8V) regulator ? There is a connection that shouldn't be there from the LAN9512 VDD18CORE pins to the 1V8 rail, those two pins are not an input for the 1.8V LAN9512 core, they are there for the decoupling caps for the internal 1.8V re...

Re: Help with RS232 GPIO connection

USB<->serial adapters are useless since you still need the level conversion from the R-Pi digital pins to RS232 levels. Regular serial adapters work from RS232 levels and some of the cheap ones you can get from eBay don't work very well.

Re: Help with RS232 GPIO connection

If you want to get the serial interface via a USB virtual serial port you can get one of the FTDI232 breakout boards from SparkFun Electronics. http://www.sparkfun.com/products/718 I currently have the R-pi serial console wired through it and works like a charm. Here is a picture of my current setup...

Re: Raspberry Pi Cooling system? :D

I took a RadioShack heatsink and hacksawed a piece of it off for the LAN9512. I dug out my Artic Silver and stuck that on the LAN chip and the rest on my SoC. About a ten minute job including the sawing. If you don't want to use a saw you can try this from SparkFun http://www.sparkfun.com/products/...

Re: Kernel panic

Still trying to find what changed that apparently fixed the kernel panic.

The GPU firmware version changed:

version 320121 (release)

Is there any place where updates/changes to it are posted ?

Re: Kernel panic

@dwilkin it is not a boot panic, and don't seem to be related to the keyboard. But I'm happy to report that it seems to have been fixed on the wheezy beta kernel, I'll run a longer test but so far no panics, 0% packet loss after 2 million packets and ~450ms rtt average.

Re: Kernel panic

yep debian6-19-04-2012. Not a SD card issue, looks more like a problem with the USB driver or interrupt management on the kernel.

I'd replace the reference to windoze it reduces the level of seriousness on how you expect your letter to be treated.
