thanks for your job ! :)
I am using arch aarch64 and not armv7hl, and it is also working with a
1/ dtb are available into directory /boot/dtb/broadcom ( and not /boot/dtb )
that's where we have to cp the new dtb file.
Correct, with aarch64 they've moved (thankfully) to putting them in
2/ dts and dtsi seem to be avaible into the same directory as for
aarch64 I found a "includes" from arm directory.
am I wrong on this ?
No, the RPi is a bit of a special case in the dt case, the aarch64
basically is a minimal dts that just includes all the ARMv7 dts.
3/ I was not able to apply patch bcm283x.dtsi.patch using patch, but
was able to apply it "by hand"
by the way I tried to use command : "patch -p0 < <patchfile>",
that the good one ?
4/ at the end I have the /dev/spidev0.[0.1] files after reboot and all
tests are OK. :)
the gpiomem stuff was easy except for the <TAB> into Makefile, I had
to read it twice :)
5/ finally I was trying to make unicornhathd work so I tried all the
stuff from github. https://github.com/pimoroni/unicorn-hat-hd
dnf install -y python3-pip python3-numpy # numpy is used into examples
pip3 install unicornhathd (this will download/compile
python3-spidev that is not package into fedora repos - at least I did
not find it :) )
git clone https://github.com/pimoroni/unicorn-hat-hd
and that's it, it works fine !!
6/ is all this the same for raspberry pi 3B+ for the dtb generation ? I
guess so but I am not sure. :)
Yes, should be fairly similar across all 3 supported Pis
7/ how can we make all this stuff "official" and by default
I'm working, as I get the time, to move all the RPi HAT stuff to be
much closer to the way Raspbian works. This will include things like
being able to use config.txt to configure most overlays. There's
somethings that won't ever be the same (we're never going to enable
the legacy gpio interface) but I'm working with various upstreams to
try and mitigate that (eg being able to use RPi.GPIO on distros other
than Raspbian with the new sane interface) but the RPi support is
something I do in my own time and that has been eroded greatly of
late. That being said I think I have the config.txt stuff worked out
and I'm hoping to be able to test it RSN.
