Boot the QNX system
This section describes the steps to boot the QNX system on SCB100 board.
Setup the hardware connection
- Connect the 20V power supply to JDC1.
- Connect the USB disk to an USB port.
- Connect the serial cable on COM1 upper port.
- Connect the Ethernet cable to the Ethernet port.
- Install the RAM card on DIMM1/DIMM2.
Opening a Serial Connection Console
To open a serial connection console, take the following steps.- The serial device on the Linux host machine should show up as /dev/ttyUSBx,
where x is a number, for example /dev/ttyUSB0.
Open a minicom terminal on the Linux host machine using the following command:
$ sudo minicom –D /dev/ttyUSB0 - Set the serial port in minicom as below:
- Baud rate: 115200
- Data: 8 bit
- Parity: none
- Stop: 1 bit
- Flow control: none
Configuring the SBL Boot Options
To configure the SBL boot options, follow the steps below:- Power ON the target system.
- Press any key within 1 second to enter the SBL command shell.
- If the boot options do not match those shown below, configure them with the boot command as shown.
