My YUN RST button does not work. Does anyone know how I can get the Yun to reset after I have loaded YunSerialTerminal and in the Serial Monitor?
I am trying to reload openwrt-ar71xx-generic-yun-16M-kernel.bin and openwrt-ar71xx-generic-yun-16M-rootfs-squashfs.bin, but do not know how to do it without the RST button.
Are you sure the reset button is not working? Or could it be that Linux is not booting and therefore you think the button is doing nothing?
If it's button itself that failed (possible but unlikely) you can accomplish the same thing as a button press by carefully and momentarily shorting the two closest pins on the switch. Be careful not to short the pins to anything else while you do this. It doesn't matter which pair of pins you use, as long as they are a pair that are on the same side of the switch.
If you are able to get to a command line (SSH over the network, or using the YunSerialTerminal sketch) then you can type the "reboot" command to reboot Linux.
Yes I am sure that the YUN RST button is not working. It has a constant dim blue glow and while in YunSerialTerminal when I press the button, nothing happens.
I am trying to catch the reboot so I can reload the kernel and openwrt system files. I will try you suggestion later to short the two pins and report back with the results.
I am not exactly sure what you mean by the "two closest pins on the switch." Looking at the Yun with the leds on the right and the usb connections on the left, which are the pins you are referring to?
Are you talking about the USB LED (the one closest to the reset button)? If so, it does not mean that the reset button is not working, that dim LED seems to be an indicator that the Linux portion is bricked and not even trying to boot. If you are stuck with a dim LED and not output at all on YunSerialTerminal, I don't think you have enough running to be able to flash any code at all.
When people report a dim USB LED, it seems the usual response is to contact customer support about getting a replacement YUN.

Look at the reset switch itself. Two sides of the switch have no pins, and two sides have two pins. Shorting either pair of pins that are on the same side of the switch will accomplish the same thing as pressing the switch.
But given the above, this is probably a moot point...
