Hi all, we’ve released a utility that will update the Ethernet firmware programmed on Jetson Nano Developer Kits manufacturer prior to 5/15 (week 21 of 2019). The updated firmware corrects the following behaviors with the Ethernet port:
Enable the RJ45 activity/link LED's
Use the board's unique MAC address
The utility determines whether your system needs it’s firmware updated and applies new firmware only if required.
The week of manufacture can be seen in characters 4-7 of your developer kit’s Serial Number, located on the underside of the board. For example, a Serial Number of xxx1019xxxxxx indicated manufacture in the 10th week of 2019.
I have tried the update on my Jetson Nano DevKit, but nothing has changed at all.
The serial number looks like xxx1119xxxxxx (indicating that is was manufactured in the 11th week of 2019 - so well within the range of devices affected by the mentioned issues).
The situation before I ran the update was the following:
The ethernet activity LED (yellow) was already working, but the link LED (green) was not.
"ifconfig eth0" showed a MAC address starting with "00:04:4b".
I followed the README file. The updater indicated a successful update (“Patch OK!!!”). I triggered a restart and afterwards even a cold start, but no change occurred at all and the link LED is still off.
The MAC address was already matching the one on the sticker before I ran the update (ifconfig output). I double-checked with the DHCP leases issued by my router and the MAC address did not change after the update.
Hi Mario, that coupled with the fact that your activity LED was working, may point to your unit not being affected by these particular issues. The link LED may be unrelated or the local network setup, I am not too sure. If it’s bothersome, you could RMA your unit for another and see if the behavior is fixed on your network.
No need for RMA. My Nano works fine and I can live with the link LED not working. I was just curious because I thought this update would somehow make the LED work.
Hi Mario, since you already had your correct MAC address and link LED, it sounds like you may have a different issue than what the firmware patch addresses, sorry about that.
Hi cccheng, if your router is in ipv6 mode, it may not assign ipv4 address and you wouldn’t see it listed (unless you disable ipv6 in your Nano networking settings).
Does the MAC address that is listed reflect the correct one from the S/N sticker found on the underside of your devkit?
Hi dusty,
I follow the instruction and patch OK but the MAC address still not change.
Is there anything wrong? I have 5 jetson nano here and all of them got the same issue
