Getting started
The N1 SDP is controlled from a serial terminal that you connect to the DBG USB port. A set of files in
the non-volatile
Motherboard Configuration Controller
(MCC) configuration microSD card configures
the board. The configuration microSD card is accessible through the DBG USB port.
The board is factory-programmed with the MCC and
Platform Controller Chip
(PCC),
System Control
Processor
(SCP),
Manageability Control Processor
(MCP), and
Application Processor
(AP) firmware.
Powering up into the operating state
The minimum actions to boot the N1 SDP are as follows:
1. Connect a serial terminal to the DBG USB port on the back panel. The serial port settings must be:
• 115.2kBaud.
• 8N1.
• No hardware or software flow control.
By default, the four COM ports are connected to the following devices:
• COM<n>
Motherboard Configuration Controller
(MCC).
• COM<n+1> -
Application Processor
(AP).
• COM<n+2) -
System Control Processor
(SCP).
• COM<n+3) -
Manageability Control Processor
(MCP).
2. Turn the mains power switch on the PC tower ON. The MCC window command prompt is shown
and the system is now in the standby state. Ensure that both configuration switches on the back panel
are in the OFF (up) position. See
configuration switches.
3. To complete the powerup sequence from the standby state, briefly press the PBON button. The
system is now fully
‑
powered and in the operating state.
Editing configuration files
The configuration microSD card contains the system configuration files. To modify the system default
settings, edit or replace configuration files while the system is in standby state:
1. Ensure that the serial terminal is connected to the DBG USB port on the back panel.
2. Turn the power switch ON. The MCC window command prompt is shown and the system is now in
the standby state. Ensure that both configuration switches are in the OFF (up) position.
3. Issue the following command at the MCC command prompt on the serial terminal:
•
Cmd> usb_on
The serial terminal now recognizes the configuration microSD card as a
USB Mass Storage Device
(USBMSD).
4. Edit the existing configuration files, or Drag and Drop new files.
5. Perform a Hardware Reset by pressing the PBRESET button. The system is now in the standby state.
6. Briefly press the PBON button. The system is now fully powered and in the operating state.
