Hello,

 

actually it was not the first time the upgrade failed on this board:

- upgrade 5.11 to 5.15 -> returned successfull

- reboot

- at boot system can not find file: sun6i-a31s-bananapi-m2.dtb

(file sun6i-a31s-sinovoip-bpi-m2.dtb for BPi M2 is available)

- fixed it by linking to the existing device tree blob sun6i-a31s-sinovoip-bpi-m2.dtb

- reboot again

- no network

(my /etc/network/interfaces has been set to armbian default, same as /etc/network/interfaces.default, this happened the first time)

fixed it again by setting the correct content

 

I don't know if the upgrade process is the problem or if there is something messed up on my board...

 

Now everything is working again... But I guess it will be the same next time...

 

regards

Holsteiner


 

Hi again,

 

does anybody know why this happens?

- at boot system cannot find file: sun6i-a31s-bananapi-m2.dtb (this has happened for 3 times till now)

- /etc/network/interfaces has been set to armbian default

 

Thanks and regards.

- /etc/network/interfaces has been set to armbian default

Upgrade procedure was not tested properly, sorry. This will happen only once when board support package 5.15 is installed, and will be fixed in the future for people who won't upgrade before next release.
