RT-LAB QNX 6.3.2: Mac Address assigned during startup
Mac Address Assignment in QNX 6.3.2
During startup of the QNX OS with RT-LAB installed software, there is a script to set the mac address for the Target System.
Cloning Hard-drives
If you clone hard drives with QNX OS and RT-LAB software installed, you will run into a conflict with the mac addresses and IP address being the same.
You will have to edit the start-up script to assign a different mac address and change the IP address assigned for the QNX Target. This script can be found in the QNX directory:
cd /etc/system/enum/devices
ls -l
net
Editing the 'net' file using vi. See the attached file to locate the line where to add the MAC address to the 'net' file. Locate the hardware MAC, and add that address to the 'net' file.
The symptom of having 2 QNX targets with the same mac address is that you will only be able to ping, compile, and load models on only one of the targets at a time.
