bad CRC - root-partition mounted ro - cubietruck A20

Hi Igor and everyone else who is supporting this forum with their time and effort. Thanks in advance for reading this and giving it a thought!

• Question:

Any idea where I could turn off mounting /dev/sda1 read only?

• Problem description:

Before moving cubietruck to a new location I did an dist-upgrade, after that a reboot didn't work. First I was asked for debug and root password. After editing

I did try to solve my problems without using your help. But I did not succeed yet. Neither with installing a new image and restoring my lamp-stack from backup nor with solutions I found in this forum (changing u-boot config and so on). I did backup sd-card(16GB) and ssd(112GB) with rsync -aAhHXv to an external ext4 backup-harddrive, right after my cubietruck stopped booting.

with

sudo mount -o remount,rw /dev/sda1 / 

I can remount rw and start apache2, which doesn't start if /dev/sda1 ist mounted read only (ro) and prints an error AH000015, because it obviously can't write into in /var/log/apache2.

So my 1st goal is to mount /dev/sda1 rw. I already deleted remount on error ro in fstab, but that didn't help.

My problem seems to be, that even though sd-card and ssd came through an external test on another Ubuntu-PC

sudo fsck.ext4 -v -f -c /dev/sdx1

without problems, my cubietruck boots only readonly. https://pastebin.com/2p3udhMu, https://pastebin.com/fJfH3Pce

This is the 1st error-message I see. It could be the source of my problems. How should I remove it?
