Hi,
there are new LetuxOS kernels:
letux-5.2-rc1
letux-5.1.3
letux-5.0.17
letux-4.19.44
letux-4.14.120
Please see:
projects.goldelico.com/p/gta04-kernel/
Unfortunately display drivers in letux-5.2-rc1 for almost all devices are
broken. So please either help
to fix the issues or wait for a later -rc.
Just in case you are not aware, letux-4.19.44 is the current longterm kernel
and recommended for daily
use on our devices. You can also install it in LetuxOS Debian systems through
apt-get install linux-image-letux linux-rootfs-letux
and then an
apt-get update && apt-get upgrade
is sufficient to get future kernel (and other) updates.
BTW, here is another trick: You may (not) know that LetuxOS images created by
makesd come rooted.
This means you can simply ssh as root into the device without password check.
This is quite helpful
for developers and debugging.
You can just do
apt-get remove letux-ssh-root
to disable. Or apt-get install letux-ssh-root to re-enable. The latter of
course means that you still
have some root access to the device. Either through sudo or the serial console.
What else is going on in the LetuxOS eco-system?
We now support MIPS devices, not only ARM. Well one. The Imagination CI20
board. Just do "makesd ci20" to
get a first SD card.
Behind the scenes, we have debootstrapped mipsel variants of the Letux Debian
images. And adapted the
kernel defconfig so that we get a CI20 (Ingenic JZ4780) compatible kernel.
What is the motivation behind supporting yet another board (and not fixing all
others first)?
The main aspect is that the jz4780 also contains an SGX 544 GPU - like the
OMAP5. This should help to get
the SGX drivers working.
The other aspect is that "fixing all others first" is a Sisyphus work. It is a
never ending story. So
we can't wait until it is done. It will never be done ;) Therefore better
contribute what can be done.
Finally, we have built a second generation (mechanical) prototype of the GTA15,
the PyraPhone.
Some photos can be seen in the twitter channel
https://twitter.com/goldelico
and ED has made a nice video showing the Pyra and explaining the GTA15 board:
https://youtu.be/X3Su8LJnmd4 (GTA15 presentation is starting at 14:07).
Both devices can share almost the same software, so there is a big synergy
between both projects.
Note that although it looks almost finished, this is just a mechanical protoype
to find out if it can
be built and if components are on good positions (almost all are, some are not
that good). The PCB
traces are incomplete which means that connecting a battery has no effect :)
On a very general view, we have achieved a lot, but still not enough to get the
LetuxOS eco-system
into a self-sustaining mode. What is lacking?
* users are missing because software is not good enough for daily use
* hardware is missing because potential users complain about missing
high-quality software
* developers to polish the software are missing, because of missing (new)
hardware
You see the vicious circle? Ideas how to magically break it?
BR and happy tinkering,
Nikolaus
