RPI3 aarch64

[schuschu]

Hi,

Just started playing with https://github.com/Electron752/boot64-rpi3 and the generic armv8 rootfs.

Heads up it works (some hickups).

Best,

I tried it weeks ago, works good off hard drive for rootfs.
It might be a dead end, neither foundation or mainline.

Just tried something based on the image posted here: https://www.raspberrypi.org/forums/view ... &start=125

1) Use dd to write the image to the SD card resulting in the usual 2 partitions
2) Mount the second partition (root)
3) Remove everything on it and replace it with the content from the generic ARMv8 tarball of Arch Linux ARM
4) Empty the boot folder on the SD card (but not remove it)

It boots and I can log in without any problems, but it still needs some work since I don't have any network adapters at the moment. I will play around a little bit more and report back.

Encouraging! Based on pepedog's comment, even if this seems to work, does that imply that the Arch ARM project may not do anything official with this code?

As far as I heard the foundation did some initial stuff, but left the rest up to the community.
Other than that forum thread I posted I haven't found any semi-organized effort to try and enable aarch64 for the RPi3.
Hopefully as soon as it matures a little bit more developers are going to pick it up and maybe Arch ARM can do something to provide an official aarch64 image. But for now it seems we have to wait ...

No official AArch64 support will be provided for that platform until such time that kernel support meets or exceeds the current level of support provided by the existing installation. The company purposely chose to not develop AArch64 support for their ARMv8 system, and instead release it effectively as an ARMv7 system, and that is what it will be supported as here. If you have a use case for an AArch64 system, buy something else such as an ODROID-C2.
