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.

|
|
Update: there's another test, loop2, which performs a shorter loop,
|
|
|
|
|
which still produces corruption.
|
|
|
|
|
|
|
|
|
|
Update: loop4 does the same as loop2, but uses "pld reconfigure" instead
|
|
|
|
|
of power-cycling. Since loop2 was used for a test run #2 (NOR unlocked)
|
|
|
|
|
and a test run #3 (first 55 pages of NOR locked), there is no loop3
|
|
|
|
|
script.
