SK-TDA4VM: Error when transfering RTOS component libraries, header files and remote core binaries to the SD card

SK-TDA4VM: Unable to see video from camera when executing ./app_edgeai.py ../configs/rpiV2_cam_example.yaml

Hello,

As explained in a previous post

We are currently starting to work with the TDA4VM starter kit J721EXSKG01EVM. 

Since we have to make some modifications on the sensor.c files, we are following the Development flow stated here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-sk-tda4vm/latest/exports/docs/development_flow.html#pub-edgeai-sdk-development-flow

We are able to go through each step of the process (Skipping "Getting PSDK LINUX" and "Building the LINUX SDK from source" since we only want to modify sensor.c files on RTOS).

We are properly flashing the SDcard and properly executing the Development flow steps up until "Target side steps".

Right now we are properly executing ./init_script.sh, and we are able to detect that our camera is connected to the board:

./init_script.sh: line 152: /usr/local/lib/python3.8/dist-packages/dlr/counter/ccm_config.json: No such file or directory
CSI Camera 0 detected
device = /dev/video2
name = imx219 8-0010
format = [fmt:SRGGB8_1X8/1920x1080]
subdev_id = 2
isp_required = yes

But when we try to execute ./app_edgeai.py ../configs/rpiV2_cam_example.yaml, we get the following errors:

root@tda4vm-sk:/opt/edge_ai_apps/apps_python# ./app_edgeai.py ../configs/rpiV2_cam_example.yaml
Traceback (most recent call last):
File "./app_edgeai.py", line 71, in <module>

model_obj = config_parser.Model(model_config)
File "/opt/edge_ai_apps/apps_python/config_parser.py", line 86, in __init__
with open(self.path + '/param.yaml', 'r') as f:

root@tda4vm-sk:/opt/edge_ai_apps/apps_python#

It seems that the script can't find some files, and we have noticed that, when executing "./setup_script.sh" we have network errors despite being properly connected through ethernet (We even see the IP on screen)

Setup FAILED! : Make sure you have active network connection

How can we solve those two issues in order to have video from the RPI camera?

Just as a note: we have already tested this camera and script, with the prebuilt image from the "Getting started" tutorial: "software-dl.ti.com/.../getting_started.html" but we are not able to do so when building the sdk files ourselves.

Thank you,

David

    Hi David,

    For the first issue of:

    David Costa said:
    No such file or directory: '/opt/model_zoo/ONR-OD-8050-ssd-lite-regNetX-800mf-fpn-bgr-mmdet-coco-512x512

    This can be solved by running "./download_models.sh --recommended" which will download models used by the out of box demos.

    For the second issue of:

    David Costa said:
    /usr/lib/gcc/aarch64-linux/9.2.1/../../../../aarch64-linux/bin/ld: warning: libdlr.so, needed by /usr/lib/gcc/aarch64-linux/9.2.1/../../../libtivision_apps.so, not found (try using -rpath or -rpath-link)

    Can you run "nm -D /usr/lib/libdlr.so | grep GetDLRInput" and post the output to check if libdlr.so exist in your system, and this will also check if libdlr.so has the symbols that libtivision_apps.so is trying to find.

    And could you run "ldconfig", and then post output from running "ldd /usr/lib/libtivision_apps.so" to see if ldconfig can locate libdlr.so library?

    Regards,

    Takuma

    Hi David,

    It looks like a library is missing in the underlying system. Could you copy in the following library into your system and run "ldd /usr/lib/libtivision_apps.so" again:

    libdlr.zip

    If ldd finds all the libraries, could you try re-running the setup script?

    Regards,

    Takuma
