Update : I've downloaded and copied the NOOBS images from here. Checked the hash, and when I run it on the Pi the green light blinks once and then only the red light is on. Nothing else happens from then on.

Apparently there are logs somewhere? Where can I find info about the logs? I have a windows, freebsd and osx machine around.

I just bought adafruit pi starter kit and downloaded occidentalis. Unfortunately it doesn't boot. The power light goes on, the green light(ACT) flashes brightly for a while then goes mostly off.

With the rains and flaky internet it's taken a while but I've checked the md5 of my image.

I burnt it into a micro sd on windows (tried both with fedora arm installer and win disk imager).

I've looked at a variety of posts here, on raspberrypi.org and the PI troubleshooting page here: http://elinux.org/R-Pi_Troubleshooting

I still have to test another card, and possibly another distribution.

In the meantime this is what I want to know:

  1. I saw this 2011 thread @raspberrypi.org and they talked about a start.elf file in this github repo and how it should match the armxxx_start.elf. I want to know whether this still applies? Is there a way to play/check the *.elf files to fix my issue?

  2. This troubleshooting page says : 

    3 flashes: start.elf not found
4 flashes: start.elf not launched
7 flashes: kernel.img not found

    Does this also still apply? My ACT light flashes brightly in the beginning, then stops completely after a minute or so.

Any ideas would be extremely appreciated.

I've done the basic things like check for files in the SD card, tried with no monitor plugged in. I don't have my multimeter now, so I'll check with that soon and I'm going to try the NOOBS image.

So after hours of troubleshooting, I fixed it by changing the config.txt. I uncommented this:

hdmi_safe=1

And it worked!

Was an interesting experience troubleshooting all in all!

Info: Use safe mode settings to try to boot with maximum hdmi compatibility. This is the same as the combination of: hdmi_force_hotplug=1, hdmi_ignore_edid=0xa5000080, config_hdmi_boost=4, hdmi_group=2, hdmi_mode=4, disable_overscan=0, overscan_left=24, overscan_right=24, overscan_top=24, overscan_bottom=24. See http://elinux.org/RPiconfig.

  • @Si8 I realize this is a bit late but here is an article about several ways to edit the config.txt file, makeuseof.com/tag/edit-boot-config-file-raspberry-pi including how to do it with a PC using Notepad as your editor. In a nutshell, you need to access the SD card using a memory card reader, go to the boot partition, then use Notepad or other text editor to open and modify the config.txt file. Make sure that after saving the changes, you properly eject the card to ensure the drive is updated and not corrupted.
