Hi Gokul,

The logs look correct. Please be aware that they indicate that the system is setup, such that the display subsystem (DSS) is controlled by the R5. In this type of setup the A72 QNX GLx utilities will not go to the display, without code modifications.

If the intent is to validate that display is functional, please try running a vision apps demo such as the object detection demo, and see if there is any output on the display.

Some general notes:

Whether the the system uses an R5 controlled display or A72 controlled display, is a S/W architecture decision, that needs to be made.

The default build settings for PSDKQA7.0 are for eDP display. If HDMI display is desired, then there are two options:

HDMI port on Infotainment adapter board
An active DP/HDMI adapter can be used. Not all adapters will work, one adapter that has been tested on PSDKQA7.0 is Cable Matters 4K Active DisplayPort to HDMI Adapter (Active DP to HDMI Adapter) Supporting Eyefinity

When R5 is controlling the display, to switch between eDP and HDMI please follow documentation to ensure R5 image is built correctly.

Hello Kip,

We could like to display via A72 core.

https://software-dl.ti.com/jacinto7/esd/processor-sdk-qnx-jacinto7/latest/exports/docs/qnx_sdk_components.html#qnx-screen-release

Enabling A72 Control of DSS

It is mentioned that The ENABLE_DSS flag must be undefined, I am not able to find this flag. Is it pointing to below one ?

#define ENABLE_DSS_SINGLE

Gokul

Hi Gokul,

Yes that is the correct flag.

Follow the steps in "Detailed steps to configure and Build Vision Apps", at http://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/vision_apps/docs/user_guide/BUILD_INSTRUCTIONS.html, for file location.

In these steps as you mention, ENABLE_DSS, should read ENABLE_DSS_SINGLE.

Hi Kip,

As per email , I have done below steps & it is working.

Update the BSP so it knows A72 has control of the DSS

In file: …/sdk_rtos_auto_j7_07_00_00_11/psdkqa/qnx/bsp/images/j721e-evm-ti-spl.build

Remove the ‘-d’ line from startup:

#######################################################################
# startup options:
# -d: Use when display is managed by the R5 core (Added by TI)
#######################################################################
[+keeplinked] startup-j721e-evm -v -r0xA0000000,0x5C000000,1 -d

Remove the raw file to ensure it is rebuilt:

rm …/sdk_rtos_auto_j7_07_00_00_11/psdkqa/qnx/bsp/images/j721e-evm-ti-spl.build /fs-j721e-evm-ti-spl.raw

== 2 ==
Change the compile flags as per e2e thread and instructions to disable R5 control of DSS.

#undef ENABLE_DSS_SINGLE

Rebuild the R5 image, and replace it on SD card, with below commands

In vision_apps:
make sdk
make vision_apps
make qnx_fs_install_sd

== 3 ==

Replace the user.sh script on the SD card to enable DSS control on A72

On the SD card update scripts such that screen is started with a graphics.conf file that will control DSS from A82

cp /media/<USERNAME>/boot/scripts/user__dss_on_a72.sh /media/<USERNAME>/user.sh

== 4 ==

Boot and Now run the GL application.

Gokul

Hello Kip,

One correction: Need to undef the ENABLE_DSS_SINGLE flag.

Thanks Gokul,

Updated the steps from the previous post to read #undef instead of #define .
