README

power-cycling torture test, to see if booting into FN and then
power-cycling causes NOR corruption.

You need:
- an M1 with JTAG board
- a Lab Switch (../../labsw) to control power to the M1
- a USB connection to the Lab Switch
- the Lab Switch control tool "labsw" installed
- a USB connection to the JTAG board
- UrJTAG installed, see
  http://milkymist.org/wiki/index.php?title=Flashing_the_Milkymist_One#compile_urjtag
- neocon from http://svn.openmoko.org/developers/werner/neocon/
  (or any other program to monitor and log an outbound serial line)

Run
neocon -a -l log -T /dev/ttyUSB0

Then
./loop

This will:
- power-cycle the M1, leaving it powered off for 5 seconds
- give it two seconds to power on
- boot the "regular" bitstream, i.e., Flickernoise
- wait 70 seconds for Flickernoise to start and to render the
  "The Tunnel" for a few seconds
- repeat this forever

The log file records the console output from the M1, plus time
stamps and cycle numbers written from the "loop" script.
