The red LED coming on, indicating that the reset circuit has triggered, is a
classic symptom of the power supply being marginal - either not quite up to
3.3V, or current limiting and dropping in voltage as the board tries to
boot. The other thing I've seen cause this is an old version of the CPLD
code which had a couple of its reset pins mixed up. This would work most of
the time, but occasionally reset for no apparent reason. I'd say check the
power supply first.

The yellow LED indicates the flash chip is being accessed. Erasing the chip
does take quite a long time (30-60 seconds or thereabouts).
