Linux/AM3358: AM335x SGX driver ti-sgx-ddk 1.14.3699939

Part Number: AM3358

Tool/software: Linux

Installing SGX driver ti-sgx-ddk 1.14.3699939 on a custom board, I'm not able to start eglinfo correctly,
always getting error :

Creating Window surface..
PVR:(Error): WSEGL_CreateWindowDrawable: Couldn't set CRTC: Invalid argument [0, ]
Unable to create surface
egl error 'EGL_BAD_ALLOC' (0x3003)

Stucking with this issue for several days, any advice is highly appreciated.

Prodecure for starting eglinfo is like this :

~# insmod /lib/modules/4.4.26-rt33/extra/pvrsrvkm.ko
[drm] Initialized pvr 1.14.3699939 20110701 on minor 1
~# pvrsrvctl --no-module --start
PVR_K: UM DDK-(3699939) and KM DDK-(3699939) match. [ OK ]
~# insmod /lib/modules/4.4.26-rt33/extra/bc_example.ko

~# eglinfo

Hello Margarita,

thank you for your feedback, but the thread you mentionend is ending in nowwhere. In this
thread, Kemal explained that TI is not supporting QT issues.

My issue is not a QT issue. I'm trying to use the tool "eglinfo" from the closed source package TI
is providing for EGL functionality. I have no chance to debug or understand in any other way what's
going on in eglinfo and why this error happens, because of the closed source issue.

I would highliy appreciate any further help.

in the git repo.

Hello Oliver,

Please, first stop the weston before typing the eglinfo command.

root@am335x-evm:~# /etc/init.d/weston stop

Best regards,
Kemal

Hello Kemal,

thank you for your feedback.

Weston isn't running on this board at all, there is no weston installation in the root file system.
Therefor there is no /etc/init.d/weston script available.

The plan was, to run later QT directly on EGL, therefor no weston installation.

Best regards,

Oliver

Could you please attach these logs?

I saw this error open("/lib/libGLES_CM.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) on eglinfo.log file, which is more common on x86 architectures. On am335x it should be under /usr/lib/ directory. How did you build the ti-sgx-ddk-um, ti-sgx-ddk-um-dev. Can you attach them too?

Attached are the ti-sgx-ddk-um packages of my system as ipk-files, hope this is ok.

They have been built by a git pull from
git://git.ti.com/graphics/omap5-sgx-ddk-um-linux.git;protocol=git;branch=ti-img-sgx/1.14.3699939

This pull request downloaded the prebuild libs and binaries, which I then installed
in the root file system of my system.
The location of the libs on my root file system is definitly /usr/lib, not /lib.

Something is not okay with your libpvrDRMWSEGL.so.1.14.3699939 library. Please, replace it with this one from Processor SDK 03.02.00.05. I am attaching it for a quick test.

Hello Kemal,

thank you - the library you attached to your last post did solve my problem.

I'm not sure why, but the git clone request from my yocto environment pulled a wrong version of the library.
By manual cloning or downloading the total package from the web page I could also get the right version
of the library.

Now eglinfo is running without any problems.

Thank you for your support.

Best regards,

Oliver
