Re: [ts-7000] Implementing Shutdown Button from XDIO

[ApOgEE <>]

I'm booting from SD card where in some case, when the system experience improper shutdown, it will cause the SD card kernel corrupted and won't boot anymore. It happen sometimes where I have to dd the fresh system image to the SD card again when the board is powered on and off many times.

Does anyone experience the same problem? How did you solve the issue?

So it's working then :-) I'd guess it is shutting down the board, which is
not the same thing as shutting down the operating system!

Something like. So you simply need to use an unused DIO input connected to
a switch (NOT Pin6 on dio2 !). Then you need to write a small program that
continually (well maybe every second or 2) monitors the switch.
If it is pressed for longer than say 4 secs (whatever) then your program
executes the relevant shutdown command to stop the Operating System.

Actually, I have already done that shutdown program via DIO and watchdog. It's just I'm thinking if I could use the shutdown function in other way without using the DIO input. Anyway, if you also said like that, then I should stick with my DIO shutdown and watchdog program.

 

With a bit more electronics you could get this program to shutdown the
power to the board too.

I wish someone would love to share their experience with this electronics because I don't have any idea on how to do it yet. ;D.

Thank you
