TDA4VM: Is there a prebuilt QNX package available for tisdk-adas-image?

Thank you Asha.

From the given documentation I see it states that "Do below to build the source code using pre-built libraries provided in the SDK installer" ( on this page - https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j721s2/09_02_00_05/exports/docs/vision_apps/docs/user_guide/BUILD_INSTRUCTIONS.html#QUICK_SETUP_STEPS_QNX_TI_RTOS )

That means the "make_sdk.sh" is not going to rebuild all the libraries included inside "tisdk-adas-image".

My question is about is there a pre-built libraries package for QNX already available (with set of libraries included in tisdk-adas-image )?

If pre-built libraries are not available, where can I find the source and procedure to build that "tisdk-adas-image" package for QNX?

No, there is not an equivalent of the tisdk-adas-image (which provides part of the root filesystem for Linux) for QNX. With the QNX instructions in the earlier link, you would be able to build the equivalent files to boot the RTOS+QNX mode.

I have followed the documentation steps (wherever applicable for RTOS + QNX) given in https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j721s2/09_02_00_05/exports/docs/vision_apps/docs/user_guide/BUILD_AND_RUN.html and do not see the dynamic libraries like "libonnxruntime.so" and others which are part of tiskd-adas-image are not rebuild for QNX.

When I look at page "https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j721s2/09_02_00_05/exports/docs/vision_apps/docs/user_guide/BUILD_INSTRUCTIONS.html" it states that "Build vision apps without prebuilt libraries" i.e,, I interpret as pre-built libraries will not be re-built again.

Looking at the sdk_builder/scripts/setup_psdk_rtos.sh script, I see it is just unpacking the prebuilt tisdk-adas-image package and I could not locate any places where rebuilding of those adas libraries taking place.

PSDK_LINUX_ROOTFS=tisdk-${TISDK_IMAGE}-image-${TI_DEV_BOARD}.tar.xz

....

tar xf ${PSDK_LINUX_ROOTFS} -C targetfs/

While exploring further on the TI documentation I came across this page "https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/09_02_00_05/exports/docs/linux/Overview_Building_the_SDK.html#steps-to-run-yocto-builds-inside-container".

This page talks about building the tisdk-adas-image for Linux but there is no hint about building for QNX. 

do you think I am looking at the right place for building those libraries part tisdk-adas-image package? With reference to this are there any documentation to build for QNX?

Hi Senthil,

I am conferring with our QNX experts and will get back to you regarding this.

Best,

Asha

Hi Senthil,

Sorry for the delay in response in getting back to you. In terms of the OSRT (such as ONNX) libraries, there is no out-of-box port from TI SDK as there is for Linux. This would need to be something done on your end to support QNX.

Best,

Asha
