1	power-cycling torture test, to see if booting into FN and then
2	power-cycling causes NOR corruption.
3
4	You need:
5	- an M1 with JTAG board
6	- a Lab Switch (../../labsw) to control power to the M1
7	- a USB connection to the Lab Switch
8	- the Lab Switch control tool "labsw" installed
9	- a USB connection to the JTAG board
10	- UrJTAG installed, see
11	http://milkymist.org/wiki/index.php?title=Flashing_the_Milkymist_One#compile_urjtag
12	- neocon from http://svn.openmoko.org/developers/werner/neocon/
13	(or any other program to monitor and log an outbound serial line)
14
15	Run
16	neocon -a -l log -T /dev/ttyUSB0
17
18	Then
19	./loop
20
21	This will:
22	- power-cycle the M1, leaving it powered off for 5 seconds
23	- give it two seconds to power on
24	- boot the "regular" bitstream, i.e., Flickernoise
25	- wait 70 seconds for Flickernoise to start and to render the
26	"The Tunnel" for a few seconds
27	- repeat this forever
28
29	The log file records the console output from the M1, plus time
30	stamps and cycle numbers written from the "loop" script.
31
32	Update: there's another test, loop2, which performs a shorter loop,
33	which still produces corruption.
34
35	Update: loop4 does the same as loop2, but uses "pld reconfigure" instead
36	of power-cycling. Since loop2 was used for a test run #2 (NOR unlocked)
37	and a test run #3 (first 55 pages of NOR locked), there is no loop3
38	script.
