LinkIt Smart 7688 Duo Poweroff problem

by support4 » Thu Dec 31, 2015 1:21 am

When i do a poweroff at the console, the LinkIt Smart 7688 Duo, just reboots.
If i know I want to power it off, how can I do it when it just reboots. Correct me if I am wrong, but I though a Linux environment needs the shutdown to keep the files from being corrupted before you remove the power.

Please give to us an answer

Hello,

Please use poweroff -h command to shutdown OpenWrt based systems. BTW, these OpenWrt systems are resilent to power-off.

Thanks and Warm Regards.

One issue we are having is that if power is lost to a board which is connected to a busy WiFi access point, the chance of a file system corruption is 50/50 requiring a reflash of the eprom using a USB stick. Since this is the same OpenWRT as used in commercial routers that never have power loss file system corruption, I am wondering what I can do to avoid this situation. If the board required a micro SD card to operate properly, and had a version of OpenWRT that did not write to the eprom, that would likely avoid any possible corruption. Looking for a solution that doesn't require additional circuitry to aid in a clean shutdown on power loss. Thanks, Shannon Bailey of (IOTInventor.com) and (MakeSchool.com)

Hi, I am facing similar problem with multiple Linkit Smart Duo boards. If the board is connected to a network and there is a power reset, it sometimes fails to boot up next time. The LED glows constantly and firmware has to be reflashed.

Is there a fix for this? because most of our applications require Power Fail Safe.

Looking forward for your kind support. Thank You
