Recover Command
Sometimes a user will attempt to download the wrong file to the GPS Subsystem. When this happens
the recovery method above will not work. After issuing the
cat
command above you will not see
a series of “C” characters, but instead you will see the bootloader message being output every few
seconds. In this case you need to use a different recovery procedure.
First make sure the above
cat
command is killed by typing CTRL-C. Then enter a new
cat
com-
mand as:
cat < /dev/arm_user &
You should again be seeing the bootloader message every few seconds:
Tempus Bootloader 6010-0050-000 v 1.00 - May 28 2004 17:31:05
Please type the following command but do not press enter:
echo -e “recover\r” > /dev/arm_user
Now wait until you see another bootloader message come out and then press enter. You will then see
the “C” come out every 3 seconds. You then kill the previous
cat
command by entering:
kill $!
You should see a command prompt. Now issue this command to re-transfer the correct binary file:
upgradegps /tmp/6010-0020-000_3.01.bin
