Overview of the configuration process
The
Motherboard Configuration Controller
(MCC), the
Platform Controller Chip
(PCC) together with
the configuration microSD card, configure the N1 SDP during powerup or reset.
The MCC uses information in the configuration EEPROM and the configuration microSD card during
the configuration process, including the board HBI number.
Note
• The HBI number is a unique code that identifies the board. The root directories of the microSD card
contain subdirectories in the form
HBI<BoardNumber><BoardRevision>
, for example HBI0316A.
HBI0316A is the HBI number of the N1 board.
• If the MCC does not find a configuration directory that matches the HBI number of the board, the
configuration process fails and the board reenters the standby state.
The configuration microSD card stores N1 SDP configuration files, including the
board.txt
file.
When power is applied to the N1 board by pressing the power button on the PC case, or the PBON
button, preliminary configuration takes place and the board enters the standby state.
The MCC command-line interface is enabled in the standby state. You can connect a workstation to the
DBG USB port and edit configuration files or Drag and Drop new configuration files.
Configuration resumes after another press of the power button on the PC tower, or the PBON button. The
configuration process then completes without further intervention from the user. The system is then in
operating state and application code runs.
A long press of the PBON button, longer than two seconds, initiates a software reset of the system and
puts it into the standby state. Pressing the
Hardware Reset
button, PBRESET, initiates a forced reset and
puts the system into standby state.
