Trying to get the Sense HAT working on my Raspberry Pi with SLES12 SP2.
I’ve managed to get the sense-hat python module installed (needed to
build RTIMU from source) but when I try to instantiate a SenseHat in
Python following the example at https://pythonhosted.org/sense-hat/, I
get the error “OSError: Cannot detect RPi-Sense FB device”. No help on
the web specific to SLES, of course… can anyone provide some pointers?[/color]
Looking at the source of python-sense-hat what does “ls -la
/sys/class/graphics/fb*” output?
HTH.

rpi1:~ # ls -ls /sys/class/graphics/fb*
0 lrwxrwxrwx 1 root root 0 Nov 18 19:33 /sys/class/graphics/fb0 → …/…/devices/platform/soc/soc:gpu/graphics/fb0
0 lrwxrwxrwx 1 root root 0 Nov 18 19:33 /sys/class/graphics/fbcon → …/…/devices/virtual/graphics/fbcon
So I looked at the source as well, and it looks like it’s looking for the contents of the file /sys/class/graphics/fb0/name. That file does’t seem to have any value.
rpi1:/sys/class/graphics/fb0 # ll name
-r–r–r-- 1 root root 4096 Nov 18 19:36 name
rpi1:/sys/class/graphics/fb0 # file name
name: very short file (no magic)
rpi1:/sys/class/graphics/fb0 # cat name
rpi1:/sys/class/graphics/fb0 #
It may be worthwhile to analyze the file contents with something that does
not hide non-printable characters:
hexdump -C /sys/class/graphics/fb0/name–
Good luck.

It looks like the hat would usually trigger some device tree change (do you have to add it to config.txt on raspbian?) which then results in an additional fb device getting exposed. The upstream Linux boot flow is missing a good chunk of that magic, so SLES doesn’t have it either.
You could try and read in the raspberry pi firmware github directory the device tree overlay for that device.
That overlay refers to a new device node with a compatible called “rpi,rpi-sense”. This compatible is the identifier for the device driver to bind to the device. Upstream Linux doesn’t contain any driver for that device. The downstream raspberry pi foundation kernel has a few hits when I search for it: Video (FB), Multi Function Device and Joystick.
You might be able to port those drivers to the SLES kernel, make them 64bit aware and compile them as KMP. Once you have that, you would need to modify your system device tree manually with the device tree overlay. To do that, run
$ dtc -I fs -O dts /proc/fs/device-tree > rpi3.dts
<add overlay manually to rpi3.dts>
$ mkdir /boot/dtb
$ dtc -I dts -O dtb rpi3.dts > /boot/dtb/bcm2837-rpi-3-b.dtbIf you have ported the drivers correctly and added the device tree overlay properly, that should then give you new joystick and video support for the hat.
Please also keep in mind that because the procedure is so tedious, officially SLES for the Raspberry Pi does not include any hat support whatsoever. This is really thanks to the Raspberry Pi Foundation’s horrible stance on upstreaming code and working with the upstream community though.

Well, not terribly useful, I think:
rpi1: # hexdump -C /sys/class/graphics/fb0/name
00000000 0a |.|
00000001At least now you know there’s something in there: a newline (0x0a).

Good luck.

Thanks for the pointers, maybe I’ll try to do something with it over the Thanksgiving break.
I’ve managed to build the drivers, and get the python sense-hat and RTIMULib installed. I was even able to pull sensor data from the hat. Wahoo! The last step is getting the framebuffer instantiated, which means doing the device tree overlay. I’m new to this, so thus far my efforts to manually integrate the overlay into the device tree have failed. My kernel module is at https://github.com/darthzen/pisense.
Any help or guidance to let finish this off would be greatly appreciated.
