Some small number of developer kits have a manufacturing problem that can impact WiFi.
Please go to https://developer.nvidia.com/embedded/support to download and run the wifi-config-check tool to find out whether you need to request a replacement developer kit via the RMA Process. Use the wifi-config-check tool to determine for sure, but signs of the affected behavior include:
- clicking on the desktop Network Manager, shows WiFi “device not ready”.
- dmesg kernel log includes repeating “mmc1: Data CRC error” followed by register dump. For the full text see: https://devtalk.nvidia.com/default/topic/897947/embedded-systems/wireless-problem-on-tx1/post/4737452/#4737452
- system may be laggy from the repeated loggings noted above. Until your replacement arrives, temporarily disable WiFi to remove the lag:
$ sudo mv /lib/firmware/brcm /lib/firmware/brcm_ $ sudo reboot
- scanning for WiFi networks will result in failure:
$ sudo iw dev wlan0 scan command failed: Network is down (-100)
Thanks to those in the community for reporting earlier on their condition and S/N’s. We reached out to these individuals previously to get their process started. For others receiving factory units, please run the wifi-config-check tool to deem if your unit needs replaced. At this time we are doing advance replacement with shipments including return postage for the affected unit.
