Section 7 — Jupiter Control Center
Clear Flash
The
Clear Flash
button clears flash memory on the selected boards and
reboots them. The boards will immediately begin downloading all config-
uration and code.
Post Mortem
The
Post Mortem
button starts the post-mortem debugger on the selected
boards.
Start Board Override
The
Start Board Override
button is a troubleshooting tool. When the
Start Board
Override
button is selected, and a board selected and booted, the basic oper-
ating system will launch but the Jupiter processes will not start. Boards in
this state will display a Probe message similar to
“
pmemOverrideStartBoard is set, not starting this
board.
”
Using Probe, one can enter the
startBoardOverrideShow
command
from the shell to determine if the board will or will not start up on the next
reboot. When troubleshooting is completed, either reboot the board (which
will automatically start all processes), or use the Probe command,
startBoard
to resume normal board operation.
Probe Connections
The protocol for the Serial port on the front of the CM-4400 is 9600 baud, 8
data bits, 1 stop bit, and no parity.
