hi, i tried to update my YUN (rev1) and no it doesnt boot the linux. I can connect via usb but can´t via netwrork tft etc. so I can't downdrade the firmware as arduino.cc sugest.
Either can't enter the u-boot interface with the correct prompt "root@xxxx.local:" typing "ARD" while booting only get prompt "arduino:"
this is the complete boot log
Any ideas what can I do? Please!
