6 flashes means start.elf was found, but corrupt. Can you check on Windows if start.elf matches the armxxx_start.elf from github?
The flashes were only added this weekend to try to identify how far the boot gets before failing. These are currently implemented ones:
> 3 flashes: loader.bin not found
> 4 flashes: loader.bin not launched
> 5 flashes: start.elf not found
> 6 flashes: start.elf not launched
Excellent. I write this post on a computer in one room, move to a computer in another room (the one with the working SD card reader) and your reply was waiting for me when I sat down. Thank you!
I've just downloaded the git repo from github and the latest sha1sums do
match the ones on my SD card (for all the files present in both places). So I guess I'm a bit stuck unless I revert to an earlier kernel from github or something (or wait for a fix...). Is this something other people are seeing too? I'll see if I get time to poke around on the change logs on github, otherwise I'll try to experiment tomorrow evening if I get time.
