Part Number: SK-TDA4VM
Other Parts Discussed in Thread: TDA4VM
Hello,
As stated in a previous thread:
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).
It seems like everything is working properly until we reach the "APPLICATIONS SETUP" steps:
When calling the /media/<user-name>/rootfs/opt/edge_ai_apps#./setup_script.sh script, it shows the "proc/device-tree/compatible: No such file or directory. We bypassed this error by hard coding SOC=j721e on "setup_script.sh".
This also is done on download_models.sh. Otherwise, the models are not being downloaded.
After inserting the SD card to the SK, we try to get video from the rpiV2 cam, but the following error raises:
root@tda4vm-sk:/opt/edge_ai_apps# ./init_script.sh
CSI Camera 0 detected
device = /dev/video2
name = imx219 8-0010
format = [fmt:SRGGB8_1X8/1920x1080]
subdev_id = 2
isp_required = yes
root@tda4vm-sk:/opt/edge_ai_apps# cd /opt/edge_ai_apps/apps_python/
root@tda4vm-sk:/opt/edge_ai_apps/apps_python# ./app_edgeai.py ../configs/rpiV2_cam_example.yaml
[WARNING] SOC env var not specified. Defaulting target to arm.
[ERROR] Element cannot be NULL. Please check plugins_map file.
It seems like it is related to the SOC variable we are hardcoding to "j721e", since it seems like the board is not finding this variable. What should we do to make the board work?
Thank you,
