First I try to reinstall the OpenWrt-Yun image by the web panel.
The WLAN keep blinking over 10-15 minutes and don't stop , which I think it is not right.
Then I try to do it using Terminal and I got the following error :
root@MyArduino:~# run-sysupgrade /mnt/sda1/openwrt-ar71xx-generic-yun-16M-squash
cp: read error: Input/output error
