Hi, I’ve got a couple of jetson devkits and for some reason all the wifi cards seem to have the same mac address. I’ve googled for it and it sounds like this mac address may be a testing address. I haven’t been able to change it with either ifconfig or macchanger.
The mac address they all share is “00:90:4c:11:22:33”. Here is output of ifconfig from one of our devkits.
Admittedly, I’ve never actually used the wireless, but the JTX1 I have uses a different MAC than what you list above. If more than one device wants to use the same MAC, this would indeed be an issue. I think it may be possible to change this temporarily to test via serial console during u-boot environment setup (hit a key to pause in serial console right after it boots, run “help” to see what you can alter…MAC should be on the list).
Actually it seems that sometimes it boots with MAC address “00:90:4c:16:70:01”. Right now I have three devkits all booting with that mac address. I’m not sure why sometime it’s that and sometimes its “00:90:4c:11:22:33”. In any case, thanks for the U-boot suggestion, I’ll try that.
I’m having this problem on TX1 SoC’s removed from the devkit board. On the devkit board, they all had different addresses, but running them on a small carrier card, they all end up with “00:90:4c:16:70:01”. I suppose the dev board is supplying a MAC address in some way that isn’t available once the SoC is pulled off?
What’s the right way to assign a MAC address in this case? u-boot or something else?
Thanks - hmm, u-boot documentation mentions variables ethaddr, eth1addr, eth2addr but none of these are defined on my TX1. They are supposed to correspond to eth0, eth1, eth2, so not sure if they would be picked up for wlan0.
