No longer boot with vmlinuz-4.4.154-90-rockchip-ga14f6502e045

I don’t have network now and will find a cable tomorrow. Thx!

Ok, please let us know the follow-up.

HI setq,
I am a bit confuse. If I need to expand the /boot partition, I have to unmount it, resize the ubt-bionic 62GB partition to free up some space, then expand the /boot to these free space.
So, I have to do it on the eMMC with my linux PC not on the rockpi4b?

Please take a look and while I tried to run your script on my ubuntu PC, it reads
rolly@ubuntu:~/vm_share/rockpi4b/backup$ sudo ./rockpi-backup.sh -h
[sudo] password for rolly:
./rockpi-backup.sh: 8: ./rockpi-backup.sh: Syntax error: newline unexpected
rolly@ubuntu:~/vm_share/rockpi4b/backup$ sudo ./rockpi-backup.sh
./rockpi-backup.sh: 8: ./rockpi-backup.sh: Syntax error: newline unexpected

Please run rockpi-backup.sh on rockpi4.

And please install it using the following command. Copying and pasting from Github may cause strange problems.

linaro@rockpi:~ $ curl -sL https://rock.sh/rockpi-backup -o rockpi-backup.sh
linaro@rockpi:~ $ chmod +x rockpi-backup.sh

Hi setq,
Sad to find that I cannot update to the latest kernel so I decided to reflash the eMMC to start over again with ubuntu server.
Thx anyway
