    • porting to custom device, need help

      Hello! I've been trying to port ubports/halium to my device for almost a month. It's a custom device based on https://www.quectel.com/product/lte-sc200l-smart-module-series. I have build environment from the manufacturer along with the sources and I can build android 10.(single aosp+vendor modifications git repository).

      Now I want to use halium with custom rootfs.

      Thanks to everyone who helped me from the ubports and droidian porting chats, but discussions are dissolving in the stream there, so I decided to start this topic.

      My device supports treble/gsi. I have a /vendor partition etc. I found out that in this case, I can just build boot.img with a patched kernel config and write rootfs.img to the data partition and get a working system! This is what I'm goal for now, for the first step, then I want to fully the system partition as well.

      What I did:

      1. I found a device from the same manufacturer https://gitlab.com/ubports/porting/community-ports/android10/jingpad-a1/jingpad-a1 and based on this repository, I made my own https://gitlab.com/amednyy/sharke_ubports
      2. I also had to change the build scripts: https://gitlab.com/amednyy/halium-generic-adaptation-build-tools, because I have a 32-bit platform, and for some reason the original scripts often explicitly refer to 64-bit images, tools etc.
      3. I updated the kernel config and my first success was that I got into the initramfs shell via telnet!
      4. After that, I tried to put rootfs.img to the data section, and even it loaded! I was able to get into the ubports shell via ssh!
      5. Next, I see that the screen is empty, the original partitions, with the exception of / data, are not mounted, the android container of course has not started, journalctl does not write anything and in general the system is in a barely alive state(systemctl status gives me strange message that services list is not supported) etc...
      6. I thought the problem was in mounting partitions, I looked at the partitions in the original image and saw /dev/mapper... in the chat, I was prompted that there is an initramfs variant with dynparts - this is really my case, I received several new partition files in /dev/disk/by-label, but this did not help rootfs itself, it still does not mount anything and the android container does not start.
      7. Then I tried to fix the script /usr/sbin/mount-android.sh and manually mount the vendor partition in /android/system/vendor right before the line "if ! mountpoint -q -- /vendor; then", but nothing changed after the reboot. The partition is mounted, but this does not help halium to start in any way.
        And that's where I'm stuck. I do not know where to go next, please help me understand what is wrong with my system.
        My questions:
      8. I noticed that there are big problems with the armhf architecture in the scripts, even though I have a 64bit processor, I can't switch to 64bit because I only have 32bit libraries/blobs.
      9. The program "Treble info", running on the original android, tells me that I have a 32-bit OS and a 64-bit binder, please explain how the bitness of the binder affects, can It be thereason of my troubles?
      10. how do I debug ubports init scripts? I see that initramf writes its logs to dmesg, but since the start of rootfs, I don't see anything from the init scripts of ubuntu itself.
        4.below is original android mount output, as you see there are two vendor partitions one mounted to /vendor, second to /mnt/vendor, also two more strange partitions: socko and odmko, socko has some *.ko modules and odmko is empty. What are those partitions? What is my next step?
