We recently received a batch of x10 TX2 NX modules. We are using them with auvidea JNX30-LC carrier boards. approximately 5 out of the 10 modules have hardware Mac Address of 00:00:00:00:00:00 . The result of this is that the system generates a unique mac address every time the device boots. This plays havoc with our software licensing system and also the devices relationship with a DHCP network, as the DHCP server assigns a new IP address every time the device boots.
Is it possible to set the hardware mac address back to a fixed value? If so can you provide the commands to do this please?
Many thanks and best regards
You can share the dmesg first so that we can check why the MAC address is gone.
Current MAC: 76:07:1f:53:2c:63 (unknown)
Permanent MAC: 00:00:00:00:00:00 (XEROX CORPORATION)
The output from /var/log/kern.log is available here:
Thanks for your help
Could you also share the boot up log from uart? It looks like something wrong with the module here.
I don’t know how to share the boot up log from the uart. sorry!
Try to see if it work or ask your board vendor if they don’t have pin out.
Just a bit of added information: Serial console programs (all that I know of) have the ability to “log” the session. That log shows up on the host PC. I suggest just starting serial console before the Jetson is powered on, and look for the logging function to enable it. Then start the Jetson. It’s simple to attach the log to the forum thread.
