Hardware Arduino Yún
1

I was trying to install linuino. First i install wrong one then it cancel it in the middle of installation.

  1. step

$ cd /tmp
$ wget http://download.linino.org/linino_distro/master/latest/openwrt-ar71xx-generic-linino-one-16M-squashfs-sysupgrade.bin
$ sysupgrade -v openwrt-ar71xx-generic-linino-one-16M-squashfs-sysupgrade.bin

After that Yun part was bricked.

  1. step

Then i tried u-boot re-flash.

After i upload the YunSerialTerminal example USB port stopped working.

I tried everything from holding all reset buttons to press reset while upload new code.
Do you maybe think there is any option to fix it?

Thank you.

Did the COM port disappear or it is there but you can't upload sketches?

It disappeared. I was trying other arduinos on the same port and they worked.

I also tried to program it through other arduino and it didn't work too.

Do the LEDs on the board light up? Did you connect external hardware to your board?
