AsteroidOS installation in Raspberry Pi?

[dpnkrg]

It is possible to install AsteroidOS in any of the Raspberry Pi based boards?

My idea is to make/build AsteroidOS for the raspberry pi based board and for the touch screen, I will use any of the GPIO based raspberry pi compatible touch screens.

If anyone knows, How to start or any instructions?

I would recommend getting familiar with Yocto first. Yocto has a raspberry pi support layer. The Porting Guide may help you get a rough idea of what it takes to port AsteroidOS to a different device https://asteroidos.org/wiki/porting-guide/ it mostly targets watches running Android through libhybris but it is also possible to run AsteroidOS on a more standard Linux system, this is, for instance, what we do in QEMU. I would recommend grepping our Yocto layers for qemux86 to see how this would work.

Any update?

Any update?

Not to my knowledge. You asked for instructions and @FlorentRevest gave you some starting points. If you didn't do anything, probably no one has.

@jrtberlin, I will try and update you all.

OK finally an update :smile:

Getting AsteroidOS to work on a Raspberry Pi 4 can be done by following these steps:

Preparing sources

• Clone https://github.com/agherzan/meta-raspberrypi/tree/scarthgap to /src (git clone --branch scarthgap https://github.com/agherzan/meta-raspberrypi.git)
• Add it to the build/bblayers.conf:

  BBLAYERS = " \
  ${SRCDIR}/meta-raspberrypi \
  ...

• Add the raspberrypi4-64 platform to prepare-build.sh:

  declare -a devices=("raspberrypi4-64" ...)

• Remove dsme from IMAGE_INSTALL in asteroid-image.bblass to avoid bootloops (https://github.com/AsteroidOS/meta-asteroid/blob/master/classes/asteroid-image.bbclass#L12).
• Add input group to the ceres user to fix permission issues when opening a touchscreen device (https://github.com/AsteroidOS/meta-asteroid/blob/master/classes/asteroid-image.bbclass#L20).
  • Fixed: https://github.com/AsteroidOS/meta-asteroid/pull/198

Build

• Build AsteroidOS as you normally do (https://wiki.asteroidos.org/index.php/Building_AsteroidOS) but use the raspberrypi4-64 platform/MACHINE.

Flashing

• Flashing is a bit different than other devices. meta-raspberrypi uses a tool named bmaptool (https://github.com/yoctoproject/bmaptool/).
• Navigate to build/tmp-glibc/deploy/images/raspberrypi4-64
• Flash using bmaptool copy --bmap asteroid-image-raspberrypi4-64.rootfs.wic.bmap asteroid-image-raspberrypi4-64.rootfs.wic.bz2 <SD CARD>.
  • Replace SD CARD with your target device (often /dev/sda or /dev/mmcblk0).

Now you should have AsteroidOS running on a Raspberry Pi!

For some reason it's suffering from a weird issue where launching any apps show up garbled with a GPU related message (vc4-drm gpu: swiotlb buffer is full). Increasing the GPU/CPU memory split doesn't seem to do anything.
