Part Number: MMWCAS-DSP-EVM
Other Parts Discussed in Thread: TDA2,

Tool/software:

I am trying the tda2xx_cascade_linux_radar under vision_sdk, according to the VisionSDK_Linux_UserGuide.pdf.

(1) Change Rules.make

MAKECONFIG?=tda2xx_cascade_linux_radar

MAKEAPPNAME?=apps

(2) build

make linux

make linux_install

make -s -j depend

make -s -j

(3) Make root filesystem

cd $INSTALL_DIR/ti_components/os_tools/linux/targetfs

tar cvf tisdk-rootfs-image-dra7xx-evm.tar.xz ./*

mv ./tisdk-rootfs-image-dra7xx-evm.tar.xz /opt/PROCESSOR_SDK_VISION_03_08_00_00/vision_sdk/binaries/apps/tda2xx_cascade_linux_radar/hlos/linux/boot/

(4) Modify uenv.txt

cd /opt/PROCESSOR_SDK_VISION_03_08_00_00/vision_sdk/binaries/apps/tda2xx_evm_linux_all/hlos/linux/boot/

vi uenv.txt

fdtfile=dra7-cascaderadar-infoadas.dtb

(5) SD card

cd $INSTALL_DIR/vision_sdk/build

sudo ./hlos/scripts/linux/mksdboot.sh --device /dev/sdb --appname apps --makeconfig tda2xx_cascade_linux_radar

(6) Booting TDA2xx EVM with this SD card

(7) DEMO execute

cd /opt/vision_sdk

source ./vision_sdk_load.sh.

./apps.out

(8)Menu of demo

select6:

select7:

Check /mnt

Check mount

Hello Lei,

Are you following any procedure to mount the SSD correctly to the TDA2 system?

Please see e2e.ti.com/.../5085488 https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1333000/mmwcas-dsp-evm-mmwcas-dsp-evm/5085488#5085488

Hi Josue,

Thank you very much for your response. I have followed the steps and successfully mounted /dev/nvme0n1p1 to /mnt/ssd, and I used cascade_radar_multi_datacollect USECASE to save the raw data. However, I would like to use PTP to synchronize the time between the MMWCAS-DSP-EVM and the other sensor. I noticed that /dev/ptp0 already exists in the Linux system on the MMWCAS-DSP-EVM, but I couldn’t find tools like ptp4l.Therefore, I need to compile linuxptp for the Linux system on the MMWCAS-DSP-EVM. How can I compile and install it on the MMWCAS-DSP-EVM's Linux?

Hi Josue，

I have obtained ptp4l through cross-compilation, moved it to the MMWCAS-DSP-EVM, and the version is 1.92. Next, I plan to perform PTP time synchronization with the host. What I want to know is whether I can assign a new timestamp to the raw data by modifying the following time retrieval API?
