Raspberry Pi Forums

I recently received my pi, and since I am having very serious keyboard input problems with Raspbian ( and Logitech Illuminated wired keyboard) I have installed Arch and it's working great.

Today a colleague, who also has a pi, reminded me that it's possible to overclock the cpu. When I got home I tried overclocking to 1000mhz only to start getting some error on bootup; I had to revert my changes to /boot/config.txt in order to get the pi booting again.

Is it possible that it wouldn't boot because I have an older version of the firmware? Is it even possible to install the firmware via arch? If so, please tell me how. I've had a look around and only managed to find how to update the software using pacman -Syu. I would do it via Raspbian, but the keyboard problems are so severe I can't manage to type "raspberry" in order to log in :/

Your Keyboard symptoms are indicative of Power supply issues. Can you measure the voltage between TP1 and TP2 on the Board. If this is less than 4.75 Volts, you should look to your Power Supply, Cable and the F3 Polyfuse on the Board as possible causes. This is well discussed in many threads o this Forum.

Thanks for the tips.

I'm using an Apple plug and a no brand cheap cable, possibly it's the cable? I'll try plugging it in elsewhere and see if things improve. However, The keyboard works fine in Arch after I updated the software, and Arch only had minor input problems before the update anyway. I also tried the power supply of my Nexus 7 (5v, 2a) and had nothing improve, so I think I'm going to just buy another keyboard.

So, do you know if it's possible to update the firmware via Arch?

I borrowed a keyboard from work, which fixed the input problem and then just updated via raspbian.
