A colleague was able to setup this demo, but I am having trouble setting up the demo in my location. I want to run the ./run_app_multi_cam.sh demo.

I am following this guide:

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/vision_apps/docs/user_guide/ENVIRONMENT_SETUP.html

I downloaded the Jul 6, 2026 version of "ti-processor-sdk-rtos-j721e-evm-11_02_01_03.tar.gz" on an Ubuntu 22.04 laptop.

https://www.ti.com/tool/download/PROCESSOR-SDK-RTOS-J721E/11.02.01.03

...

My steps:

1) Download "ti-processor-sdk-rtos-j721e-evm-11_02_01_03.tar.gz" and the 2 data_set files on an Ubuntu 22.04 computer

2) Perform step 1a, 

cd ${PSDKR_PATH}

./sdk_builder/scripts/setup_psdk_rtos.sh

 

4) Perform the Linux+RTOS mode step

cd sdk_builder

make sdk -j8

 

5) Prepare SD card for boot

umount /dev/sdb1

umount /dev/sdb2

 

cd ${PSDKR_PATH}

sudo sdk_builder/scripts/mk-linux-card.sh /dev/sdb

 

6) Copy/untar file systems

cd ${PSDKR_PATH}

sdk_builder/scripts/install_to_sd_card.sh

 

7) Copy test data to SD card

cd /media/$USER/root1/

mkdir -p opt/vision_apps

cd opt/vision_apps

sudo tar --strip-components=1 -xf ${path/to/file}/psdk_rtos_ti_data_set_xx_xx_xx.tar.gz

sudo tar --strip-components=1 -xf ${path/to/file}/psdk_rtos_ti_data_set_xx_xx_xx_{SOC}.tar.gz

sync

 

8) Copy executable to SD card

cd ${PSDKR_PATH}/sdk_builder

make linux_fs_install_sd

...

I get errors when I run step 8. Looking back, I don't see any files in the root1 or boot1 partitions when I run Step 6. But I also get no error messages when I try to run Step 6.

...

Do you have a solution for the error that I am seeing? Or am I running the wrong instructions?

Best,

Justin Phan
