Hi, We are testing our orange pi one in critical external environments like warehouses, manufacturing and other. In some cases, even if the good case there is a misconnection between the sd card and the orange pi one. Connected in ssh i can access the orange pi but a lot of command cannot responde anymore, like ls, top, htop, tail and others. Even the reboot shows me the input-output-error, and the only way to reboot the hardware is using "echo b > /proc/sysrq-trigger". When this happens, i tried create a cron with 'at' or background jobs using sh like './script.sh &' with the content "echo b > /proc/sysrq-trigger" but still not works. My question is, when i remove the sd card from the board a lot of i/o features are disable. How can i identity and reboot when this happen automatically? i am using orange pi one based on linux 4.14 ubuntu xenial. Thanks

Makes all sense. I will try it and reply after. Thanks in advance

I'm using the driver nl80211. Also a tried different chipsets using different usb wifi dongle but still same result. The strange part is, using the same usb dongle with a ubuntu mate to raspberry works.

Anyone ?

Hi, I am using orange pi one with the ubuntu desktop version. When i am trying to change the region using 'iw reg set US' and after retrieving the value using 'iw reg get' still the region are not changed. I was following the doc. https://null-byte.wonderhowto.com/how-to/ultimate-guide-upping-tx-power-kali-linux-2-0-0168325/ and was able to do it all steps but impossible to change region. Can anyone help me in this issue? Thanks in advance
