Display HP S410u possible workling with RaspberryPi

[Mahdi2016]

Hi Michal,

I use Debian Jessi (raspbian) on my RaspberryPi 2.
The system is up-to-date.

Here is the output from 'uname -a' command of the terminal window is at follows:

Linux raspberrypi 4.4.34-v7+ #930 SMP Wed Nov 23 15:20:41 GMT 2016 armv7l GNU/Linux

Here is the output from 'lsmod | grep drm' command of the terminal window is at follows:

drm_mipi_dsi            8702  1 vc4
drm_kms_helper        101028  3 vc4,evdi
drm                   262564  5 vc4,evdi,drm_kms_helper
syscopyarea             2945  2 evdi,drm_kms_helper
sysfillrect             3443  2 evdi,drm_kms_helper
sysimgblt               2069  2 evdi,drm_kms_helper
fb_sys_fops             1309  1 drm_kms_helper

Here is the output from 'xrandr --listproviders ' command of the terminal window is at follows:

Providers: number : 1
Provider 0: id: 0x43 cap: 0x2, Sink Output crtcs: 3 outputs: 1 associated providers: 0 name:modesetting

What kind of OS do you use on your Raspi?

Hi, at the moment it's Ubuntu MATE.

Cheers,

Hi Michal,

I use ubuntu mate (16.04) on my RaspberryPi 2.
The system is up-to-date.

The outputs are the same.

I will try to install 'evdi' and 'evdipp' tomorrow, and hope it will work.

My goal is to just using the USB monitor..

Best regards

Hi Michal,

I use ubuntu mate (16.04) for my RaspberryPi 2.
The system is up to date (apt update, apt upgrade). After trying 'sudo BRANCH=next rpi-update' and 'sudo rpi-source' the current kernel and sources was installed.
I also try to add the following lines into '/boot/config.txt’:

dtoverlay=vc4-kms-v3d
gpu_mem=128

I tried to compile dkms. This broke with the following error message:

Error! Bad return status for module build on kernel: 4.4.36-v7+ (armv7l)

The same are with the evdi version 1.2.64, 1.2.65 and devel.
A try with the original installation package 'displaylink-driver-1.2.65.run*' end also with a similar error.

I've built the evdipp package without errors. so far so good

What steps have you done until to compile evdi and running the module?

Best regards
Michael

I didn't use dkms, just used make to build in place. I think the problem you have is this:

echo >&2 "         Run 'make oldconfig && make prepare' on kernel src to fix it.";      \

Hi Michal,

After successfull build the evdi module and reboot
The Build of evdi are successfull.

Here is the output from 'example' command of the terminal window is at follows:

pi@pi-desktop:~/target/bin$ sudo ./example EDIDv1_1440x900
terminate called after throwing an instance of 'boost::filesystem::filesystem_error'
  what():  boost::filesystem::directory_iterator::construct: No such file or directory
Aborted (core dumped)

And here is the output from 'monitorsim' command of the terminal window is at follows:

pi@pi-desktop:~/target/bin$ sudo ./example EDIDv1_1440x900
terminate called after throwing an instance of 'boost::filesystem::filesystem_error'
  what():  boost::filesystem::directory_iterator::construct: No such file or directory

      after 399 requests (399 known processed) with 0 events remaining.

After the fourth "[libevdi] ioctl: drop_master error=-1" the screen was blank.

The output from 'lsmod' command of the terminal window is at follows:

sysimgblt               2069  2 evdi,drm_kms_helper

I've built the 'evdi' and 'evdipp' under the current kernel and without errors.

What steps have you done until to compile evdi?

How did you actually compile evdi? Runs under ubuntu mate an USB monitor (DL31xx) e.g. HP s104u?

I havent any ideas anymore..

Best regards
Michael

..does anyone else have an idea?
