After buy my arduino yun rev 2, i have upgraded the Openwrt of version openwrt-19.07.0-ar71xx-generic-arduino-yun-squashfs-sysupgrade.bin
After that my wi-fi device is not working (blue led not blinking).
I have tried to reset the wifi through its reset button for more than 30 seconds, nothing happened.
Can any one help me please ?
Does the same happen with 19.07.4 (ar71xx) or snapshot (ath79)?
Hi @tmomas, thank you for your replay and sorry for my bad english
After a long fight, i solved my problem by following the instructions in the link https://www.arduino.cc/en/Tutorial/YunUBootReflash#setup-a-tftp-server-on-windows
It's true that it's not the version i wanted to upgrade, but i found my wifi and the dashboard
To be continued... target : yun rev 2 with openwrt 19.07.4
