[meta-raspberrypi] RPi 7" Touch Display

[meta-raspberrypi] RPi 7" Touch Display

[Rudolf J Streif]

I am trying to use the "official" RPi 7" touch display 
(https://www.raspberrypi.org/products/raspberry-pi-touch-display/) with 
meta-raspberrypi (most recent from master). However, I cannot get it to 
work. As a matter of fact the display does not even show the GPU rainbow 
screen making me think that the GPU firmware packaged with 
meta-raspberrypi does not support the DSI display. It works just fine 
with the latest Raspbian release (screen and touch).

I searched the web up and down but could not find anything. Maybe 
somebody has an idea? Wrong firmware (maybe cannot be distributed 
because of licensing...)?

Thanks,

Rudi

I'd recommend looking at https://github.com/agherzan/meta-raspberrypi/blob/master/docs/extra-build-config.md to see if there's some extra option you need to enable. If there's nothing documented there then raise an issue on the GitHub repository.

Sadly we don't actively test display and other related toys so they
might be broken. Even so, I would be surprised if the DSI port doesn't
work. What is you final config.txt (pastebin it please)?

Thank you, Andrei. Much appreciated.

It's the config.txt that is packaged with the image.

Thank you, Paul. I did read Andrei's excellent documentation and enabled 
I2C and SPI etc.

No, unfortunately not. HDMI works just fine but no video on the touch 
display.

I don't know if it's helpful, but I'm struggling with a similar issue on my
RPi 3 B+, where the official touchscreen, as well as, the HDMI don't output
any graphics, although detected correctly. (See:
https://lists.yoctoproject.org/pipermail/yocto/2019-May/045277.html)
After experimenting with sumo, thud and the latest master recipes, I
remembered a conversation on Andrei's GitHub project (
https://github.com/agherzan/meta-raspberrypi/issues/228), which isn't
exactly related to my issue, but I gave it a try to switch the machine from
"raspberrypi3-64" to "raspberrypi3" in order to get a 32 bit version of the
same build (of master) for core-image-x11.
However, ... this image works for the DSI port, as well as, for the HDMI.

This isn't a real solution, but at least a point to start investigating the
problem and comparing the two builds. Will try to find some time, during
the coming week, to do so, ... although I'm not experienced with the RPis -
maybe I can find something.

Regards,
Bernhard

are you building 64bit or 32bit images ?
are you using vc4grpahics or userland graphics ?

Thanks, Khem. 64 bit, raspberrypi3-64 machine with vc4graphics.

Please try 32bit we only have hdmi tested in 64bit this far

I tried to build for 32 bit with:

Build Configuration:
BB_VERSION           = "1.43.0"
BUILD_SYS            = "x86_64-linux"
NATIVELSBSTRING      = "universal"
TARGET_SYS           = "arm-poky-linux-gnueabi"
MACHINE              = "raspberrypi3"
DISTRO               = "poky"
DISTRO_VERSION       = "2.7+snapshot-20190519"
TUNE_FEATURES        = "arm vfp cortexa7 neon vfpv4 thumb 
callconvention-hard"
TARGET_FPU           = "hard"
meta
meta-poky
meta-yocto-bsp       = "master:ff472ffbb0d143de8187d84dbbf18453318f303f"
meta-raspberrypi     = "master:7059c374512f1c1c0df9ecab0703d11438bdf78b"
meta-oe
meta-multimedia
meta-networking
meta-python          = "master:1ecd8b43645883cd4fa652826e93137c942dd82c"

However, mesa-gl; now fails compiling:

ld: src/gbm/cd6bfad@@gbm@sha/main_backend.c.o: in function 
`_gbm_create_device':
| 
/usr/src/debug/mesa-gl/2_19.0.3-r0/build/../mesa-19.0.3/src/gbm/main/backend.c:104: 
undefined reference to `gbm_dri_backend'

I have not encountered that before when building for raspberrypi3 before.

Khem,

Yes, the 32-bit image (raspberrypi3 machine) works.
