Wifi resetting and original settings don't work

Hello,

Pressing the WiFI reset button didn't work anymore. The led indicator didn't blink as expected :-( 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: http://arduino.cc/en/Tutorial/YunUBootReflash here the log:


ar7240> tftp 0x80060000 openwrt-ar71xx-generic-yun-16M-kernel.bin;

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

Fixed !!! :) :) :)

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 (http://sourceforge.net/projects/tftp-server/) 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 Francesco
