Wifi resetting and original settings don't work

Hardware Arduino Yún

Hello,

Pressing the WiFI reset button didn't work anymore. The led indicator didn't blink as expected :frowning:
I used the YunSerialTerminal sketch to check the kernel boot and there was an error:

Then I tried to reflash the kernel according the guide in:

here the log:

What can I do ? any hints?
U-Boot now ends with a "Bad Magic Number" :-((
thank you

Fixed !!! :slight_smile: :slight_smile: :slight_smile:

I realised that the message displayed in the terminal " loading T T T T ..." was a timeout and the TFTP server was not working.
So I changed server and by installing Open TFTP Server (Open TFTP Server download | SourceForge.net) I solved.
I launched the server as standalone it's not needed to install it as service (on windows)

I flashed again kernel and rootfs and now I see again the WLAN

Ciao
