Questions about porting SailfishOS to an aarch64 device

Hardware Adaptation
#1

Hello, we are going to run sailfishOS on our Linux ARM64 platform “Rockchip” development. but I have some problems and would like to ask you.

I consulted the SailfishOS - HardwareAdaptationDevelopmentKit - 4.1.0.0. PDF, found that compile SailfishOS need to rely on ANDROID, it makes me very don’t understand, Can I just need a SailfishOS app and not an Android compatible app? Can I use the Linux standard for the hardware adaptation layer? In my understanding, can I regard sailfisOS as a rootFS and load the file system directly after loading the kernel?

#2

Moved to Hardware adaptation. Also, please don’t double-post, one topic is enough.

Yes, most SFOS ports rely on Android parts for the low-level stuff. The links from the Architecture page provide some information about that (although not very detailed).

There is one port for x86_64 which runs on top of regular Linux - maybe the author can provide some guidance how they achieved that.

My first post, sorry, I’ve Moved to Hardware Adaptation。

I looked at Architecture | Sailfish OS Documentation

Here is this passage: In the hardware adaptation layer, Sailfish OS uses a Linux kernel with hardware-specific additions.Sailfish OS can run on top of standard Linux hardware with native drivers, or one can utilize the drivers for an Android-compatible hardware via libhybris, which bridges Linux libraries (based on GNU C) with those based on Bionic, Such as Android. Building an adaptation for Android-compatible hardware is easily documented in HADK documentation."

So, how do I compile a SFOS using only the Linux kernel with Hardware, without libhybris

There is also a port for pinephone which is not using libhybris afaik:

see https://github.com/sailfish-on-dontbeevil
and Adaptations/PinePhone64 - Mer Wiki

I just mashed together firmware, kernel, and initramfs from ubuntu with the latte port.

Thank you very much, I refer to the https://github.com/sailfish-on-dontbeevil I have “” bringing up my device.

I used the Linux common kernel and mounted rootfs for Sfos. Like this:

But his picture has been stuck in this picture, my serial port display program has been to the file system, why did not enter the UI? Thanks.

I found something that seemed to help：
When it starts up：

There seems to be something wrong with that…

I would advise to use the #sailfishos-porters channel on telegram and irc (and matrix maybe)
there will be people that can help that are not always on the forum
