upgrade firmware openwrt arduino yun rev2

Thank you for your reply ShapeShifter.

yes the date seems correct:

root@LEDE:Date 
Mon Apr 29 23:50:21 CEST 2019

and I access the internet.

root@LEDE:~# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
64 bytes from 8.8.8.8: seq=0 ttl=121 time=26.069 ms

However, I no longer have access to the web page!

No page is registered at '/webpanel/homepage'.
If this url belongs to an extension, make sure it is properly installed.
If the extension was recently installed, try removing the /tmp/luci-indexcache file.

I copied and deleted the file, but without success!

Yet I had installed from the OpenWrt site a version "Yun" but rev : unknow

lede-17.01.6-ar71xx-generic-yun-16M-squashfs-sysupgrade.bin

So I do not have:

  • nor web interface
  • no possibility to update
  • nor even access to the SD card.(see attachment)

I add that I tried to reinitialize the distribution OpenWrt-Yun to its out of the box state by pressing more than 30 seconds on the button "Yun-RST": without success since apparently this action does nothing on LEDE-17.01.6 or brings the state to the last flashed image ie 17.01.6.
And... effectively this is the last flashed image that reappears ...

so if we see the good side of things, I still have the terminal (on br-lan not eth1???) ( and the YunSerialTerminal (from Arduino Side)

I think the game is over!
