I am getting 2 errors when booting Linux with the Vision SDK.

[FAILED] Failed to start Load Kernel Modules.
See 'systemctl status systemd-modules-load.service' for details.

[FAILED] Failed to start Network Service.
See 'systemctl status systemd-networkd.service' for details.

Here is the output from the systemctl commands:

I changed the Eth0 static IP address following the instructions in the mmWave Studio Cascade User Guide section 11.1.

I built Linux following the instructions in Vision SDK (v03.08.00) Linux User Guide sections 2 & 3.

I set MAKECONFIG?=tda2xx_cascade_linux_radar in vision_sdk/build/Rules.make but I had to change fdtfile=dra7-cascaderadar-infoadas.dtb manually in the /vision_sdk/binaries/apps/tda2xx_cascade_linux_radar/hlos/linux/boot/uenv.txt file, for some reason it was trying to use dra7-infoadas.dtb which does not exist in the /boot directory.

I tried building with and without the patches applied from Vision SDK Linux Cascade Radar Data Acquisition Tool User Guide.

How can I fix these 2 failures?

Hi Thomas,

Can you please share complete dmesg og?

I have not tried this with cascade radar dtb but with infoadas.dtb, did not see the issue.

Thanks

Hi Tom,

I see dra7-evm-infoadas.dts in arch/arm/boot/dts directory. Can you build this and check the behaviour?

Thanks

Hello Ramprasad,

This .dtb file was not able to boot. The kernel boot stopped after a message saying "[ 4.222083] Waiting for root device PARTUUID=75860135-02..."

I build the .dtb file with the following 2 commands:

1. cpp -nostdinc -I <your base installation path>/Processor-Sdk-Vision_03_08_00_00/ti_components/os_tools/linux/kernel/omap/include -undef -x assembler-with-cpp dra7-evm-infoadas.dts dra7-evm-infoadas.dts.preprocessed
2. dtc -O dtb -o dra7-evm-infoadas.dtb dra7-evm-infoadas.dts.preprocessed

Here is the boot messge:

Starting kernel ...

Here is the contents of my uenv.txt file in case it helps:

fdtfile=dra7-evm-infoadas.dtb
args_mmc=part uuid mmc 0:2 uuid; setenv bootargs "console=ttyO0,115200n8 vram=16M root=PARTUUID=${uuid} rw rootwait ip=none mem=1024M cma=64M"

I get the following warnings when running the dtc command to build the .dtb file:
