Issues with Ubuntu for ARM #18

Open mbandala opened 1 year ago

mbandala commented 1 year ago

I tried this with the DE10-nano board running the provided LXDE Ubuntu 16.04 image (login needed to get it - https://download.terasic.com/downloads/cd-rom/de10-nano/linux_BSP/DE10_Nano_LXDE.zip).

I followed all the steps for Ubuntu ARM but nothing seems to happen after rebooting. /overlay/lower is not even created and of course all changes are NOT lost after rebooting again.

I can see the prompt changing though (with an 'RO' at the end). Executing 'rootwork' confirms that there is no overlay (it says there is no /overlay). How can I debug this issue? It seems like the scripts are not executing. I noticed that the Ubuntu Linux comes with not fstab file. The bootloader is in charge of mounting the / partition here. I created an fstab file for the command 'sudo update-initramfs -k $(uname -r) -u' to work. I also noticed that the fstab file is not modified at all. Is this supposed to happen? I am sure that I created the fstab file correctly. The is a fat partition that is now mounted fine by the fstab.

I have access to the bootloader code if anything could be changed to that to make overlayroot work. Any ideas?

I'm guessing it's something to do with initramfs.

what does the output of dmesg look like?

mbandala commented 1 year ago

Hi - I see no reference to initramfs at all. I have uploaded a file with the dmesg output.

as far as I know, there should be a message about initramfs.

potentially the first part of the dmesg output has been cut off. I expected the first line to be the linux kernel version

mbandala commented 1 year ago

The attached file was created by dmesg > file.txt. I have double checked this on the terminal, no initramfs or kernel message on first line. Any other way to debug this issue?
