Can't get AP mode to work

Official Hardware Classic Yún
1

Hello,

I can't get the default AP mode to work after multiple resets, and even two factory resets or unplugging the Yun for a while. I am even suspecting the wifi might've broken. The last time it worked decent was just before I plugged it to an Ethernet cable and ran the USB power from a USB port available on a wifi router.

In reading some previous posts on forum, I tried running the wifi Status sketch and it doesn't seem to be running the Bridge commands even (the serial monitor only shows "Starting Bridge"). I also tried running Serial Terminal but that doesn't seem to work either.

Any suggestions? I'm at an installation site and trying to troubleshoot this or buy a new Yun if this one's dead—I just wanted to confirm my suspicion.

Thanks,

DId you try to upload the YunSerialTerminal sketch and then the linux side with the YUN-RST button leaving the serial monitor open?

What do you see in the serial monitor after you reset?

I tried that again, I wasn't aware that I needed to press YUN-RST while leaving the console open. The last few lines here references kernel-panic, that doesn't sound encouraging...

[ 32.570000] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00
[ 32.570000]

...then it stops.

Also, I am aware I have an old version of Open-WRT, I don't have a microSD reader handy and would need to to do it over the Linino terminal, which I can't get access to without the wifi working.

Here's the full serial terminal output:

The System hangs during the boot so you can't access to WiFi.

You can update your OpenWRT image with this guide:

Ok. I was finally able to rescue the Yún following these reboot steps now. Thank you for solving this.
