Re: Pi wont boot without HDMI attached

Might a problem with the total length of your cmdline.txt - this was recently fixed to 1024 bytes but the kernel you're running doesn't have that fix in. In that case "rootwait" gets chopped (among other things) and boot fails since the root partition is not yet ready for mounting. Keep in mind that...

Report: 3.6.7+ issues

I'm running firmware revision d27ca5e5f1c3a94a0a1311e4c0dd86644f0acacc , the bleeding edge git stuff. I was trying to recompile the kernel to have a build base for my out-of-tree DVB dongle driver. Since that takes time I just run it during the night on detached tmux session. The actual source/build...

Re: Made in China & poor soldering

The red stuff is probably glue used to hold down the socket prior to soldering. I've seen it on many photos and in fact my Made in UK board has it too. Getting solder off multi-layered PCBs with metalized holes is rather tricky. I would use copper braid and change the tip on soldering iron to someth...

Re: Black screen Raspbmc

Do you have analog TV input to test it? Might be a HDMI issue. You can also force some HDMI settings (like hdmi_safe=1) in your config.txt. Read this: http://elinux.org/RPi_config.txt

Re: One PI boots fine, another doesn't with same debian imag

Some people have reported SD cards working in one Pi and not in another. It seems to be very picky about them, perhaps you got a card (or a Pi) like that as well. Try a different SD card perhaps?

Re: Init script not working

From errors you posted I would assume that your script is broken. Quite literary :) Line 16 and 17 should definitely be one line, not two separate ones. Hence the errors. So, make sure it starts with #!/bin/sh without spaces (there are scripts that have a space there and still work but I agree it's ...

Re: Init script not working

You should have a file (a link to one actually) in /etc/rcS.d called S99lcd - where 99 is a 2-digit number but unlikely to be that value. Check if it's there, it should've been created by update-rc.d command. If all you need is for the script to start at boot and you don't much care how it's done (a...

Re: I accidentally put 8.4V through my Pi

Did you connect the power through GPIO or micro USB? My guess would be GPIO as I'd expect the polyfuse to fully trip when the protection diode starts drawing too much current. With some luck your setup had enough resistance on the power supply path to form, along with the protection diode, a crude v...

Re: new firmware and kernel 3.6.y does not work!

Last time I checked, and that was not two days ago, rpi-update still fetches 3.2.27+. In order to get 3.6.7 you need to give rpi-update a specific hash code so I assume you did. Then why are you so surprised you got what you asked for? Also, 3.6.7 works for me (along with the new firmware). Did you ...

Those adapters are often very quirky, and that goes double for models powered via HDMI cable.

Define "performance". In order to answer your question you must first identify the limiting factors in your current design.
