Hi, I'm troubleshooting a boot problem with my Pi from RS.
I seem to need to leave the Pi to 'warm up' for a number of minutes before it boots, but I'm getting three different LED states and I'd like to know what they mean as I can't see them documented.
1. Quickly flashing PWR LED (3/4 times per sec). I get this with the SD card removed.
2. Slower flashing PWR LED (<2 times per sec). I get this with the SD card inserted, but the system does not boot.
3. Solid PWR LED. I get this when the system eventually boots after 5/6 minutes.
What does the 'slower flashing' state mean?
Plus, who decided to make the PWR LED red..? It looks like an error-state notification.
