problem booting to NOR?

[Steve Leung]

Hi..  I hope someone can point out what I'm doing wrong.

I want to boot into my Freerunner's NOR to try flashing different 
images, but I can't get it to work.  I've followed what's on the wiki, 
and all I get is a brief pop or crackle from the speaker, and then about 
6 seconds later the red LED flashes very briefly.  The screen does not 
light up.

I've tried all combinations of:

- USB connected/disconnected
- holding AUX/POWER for short and long periods of time
- releasing AUX or POWER first
- with/without SIM card installed

I'm assuming there should be some visual confirmation that I've booted 
into NOR - if I plug in the USB cable after following the documented 
process, the device boots normally.

I can get into NAND no problem, and the POWER and AUX buttons both work 
fine during normal use.

Does this happen to anyone else?  Does this indicate some kind of 
problem with the phone?  Would a debug board help fix this?

TIA,
Steve
