Yes I do mount the partition, and I can see the files and cat /mnt/mmcblk0p1/config.txt will output the content of the config.txt file, so it is available.

The problem is that any change I do to the file is not maintained after a reboot. Whereas in 4.7.7 the changes was still there after a reboot.

How are you changing the file?

sbp:
Like this

sudo echo hdmi_drive=2 >> /mnt/mmcblk0p1/config.txt

Do not overwrite system configuration file, just change the relevant parameter. First try it manually with an editor to see it is effective. For scripting use sed for example.

Hi bmarkus

It doesn't matter how I change the /mnt/mmcblk0p1/config.txt file

I have used :

1.  sudo echo hdmi_drive=2 >> /mnt/mmcblk0p1/config.txt     which by the way don't overwrite the file but just add a new line containing hdmi_drive=2 to the end of the file.

2. sudo vi  /mnt/mmcblk0p1/config.txt   -  and change a line and then saved it. And I verified by doing a cat  /mnt/mmcblk0p1/config.txt that the file was changed.

However, after a reboot the changes are lost.  In version 4.7.7. I did not have this problem, as any change was still present after a reboot.
