Title: Ubuntu Gnome Linux is not working
I done everything from instruction:
https://wiki.t-firefly.com/en/Co ... compile_ubuntu.html
SDK version 0.0.1 (maybe we can get newer version?).
1) When I use Ubuntu core minimal - system is working normal, when I tried to use Ubuntu Gnome then suddenly it turned out that the system is read-only - there was no such problem with the minimal image.
2) Also video is not working over HDMI but there is no information about it in DMESG.
3) Also I have a question about how to expand rootfs partition in flash? There is 7 partitions here and one partition after rootfs that's why I cant expand it with GPARTED for example.
Sum up: there is 3 problems:
1) Read only ubuntu rootfs:
2) Tiny rootfs:
3) Not working HDMI (but it is working with Android).

try to update SDK, the newest SDK seems to be v1.0.0c, v0.0.1 is too old
read the README-IMPORTANT file in google drive where you download the SDK

Author: v.redin Time: 8/2/2022 17:07
It is impossible to download 0.1.0 from this link because google says:
This file cannot be retrieved because the download quota has been reached

sorry, maybe you got a wrong link
I send you the right SDK link through PM
Please don't leak this link to someone else, SDK is part of after-sales service

The problems with read-only filesystem and small rootfs is not gone.
It is something like this:
1) If there is very small rootfs - there is also lots of errors, some services cannot start and system remain RW, GUI is working but I can barely do something with the system that has 0B free memory;
2) I tried artificially expand rootfs partition size with GPARTED - after this system starting without GUI and also without lots of services because of read-only file system. I can avoid this problem after start with this command:
mount -o remount,rw /
But services that has not started from the boot - I can't start it. Like Wayland and Gnome, for example.
SDK version 1.0.0 and the latest ubuntu from your repo.

I think it may be a problem with boot options in U-BOOT, but I also cant stay in uboot while booting - CTRL+C (like it said) is not working...

Author: v.redin Time: 8/3/2022 19:27
I really don't know what to do and why rootfs booting in read-only...

There is no such problem with debian 11 - coming out that it is a problem with your ubuntu. But your debian is Chinese language and there are lots of problems with the network here - DNS is not working and I can't see any web sites from there, but ping exact IP is working normally (for example google - 8.8.8.8).
Also we afrid thet GPU is not working too because demo video (1080@60) became a slide show...

Hi v.redin!

What contains in bootargs of your build? I have the same problem and fix it by adding "rw", like this: bootargs = "earlycon=uart8250,mmio32,0xff1a0000 swiotlb=1 console=ttyFIQ0 ro root=PARTLABEL=rootfs rootfstype=ext4 rootwait overlayroot=device:dev=PARTLABEL=userdata,fstype=ext4,mkfs=1 coherent_pool=1m systemd.gpt_auto=0 cgroup_enable=memory swapaccount=1";

Also, does your kernel source directory (in SDK) contains "ramdisk.img" file? If no, you should copy them from old version.

I also thought so, but there is no root pattern in my uboot vars. There is no RO pattern too. And there is no problem with similar uboot but booting debian. The problem is only with Ubuntu.

I also tried to add rw to boot_prefixes var like this:
boot_prefixes=/ /boot/ rw

Everything is OK with the debian. DNS is easy to fix, language fixing in mk-base-debian.sh
GPU is working normaly - there is a lot of problem with the base videoplayer, but with MPV everything is OK - 2160@60 has good performance.
Thanks for everyone - the problem was solved
