Hi.
I have a custom carrier board with Jetson Orin NX on it. Because of that, I have additional files and config files which I need to flash.
The default sdkmanager does not consider these files. So, based on The Extra Configuration File — SDK Manager 2.1.0 documentation , I add an extra json file to overwrite original json file so that my desired files gets kicked in.
this is my json file

The keys NV_L4T_DRIVERS_COMP, NV_L4T_FILE_SYSTEM_AND_OS_COMP and NV_L4T_FLASH_JETSON_LINUX_COMP are the ones which can be found the components entry in the original json files.
this is the command I run
sdkmanager --cli --login-type offline --download-folder /home/ai-blox/Desktop/test/sdkm --target-image-folder /home/ai-blox/Desktop/test/sdkm --action install --target JETSON_ORIN_NX_TARGETS --product Jetson --target-os Linux --version 6.0 --extra-config extraconfig.json --flash all --license accept
The observation is that the device is flashed OK but not with the configs I expect to see. It seems that my generated json file does not affect the flashing process.
Can you please help me with this ?
additional notes:
In the original json file, the key components.NV_L4T_DRIVERS_COMP.platforms.downloadedFiles.packageInstallParameters.additionalParameters.installCommands contains an execution command "tar -I lbzip2 -xf {{FILE_PATH}}" which untars the downloaded BSP tarball.
I re-defined exactly the same key-value in sw key in customized json file for my own carrier board:
sw.NV_L4T_DRIVERS_COMP.platforms.downloadFiles.packageInstallParameters.additionalParameters.installCommands
The key for the execBash for the above key path is as below:
"execBash": [
"echo patch file to flash "
"tar -I lbzip2 -xf {{FILE_PATH}}",
"cd {{FILE_PATH}}/bootloader/generic/BCT/",
"LINE=$(grep 'cvb_eeprom_read_size' tegra234-mb2-bct-misc-p3767-0000.dts)",
"sed -i \"s|${LINE}|cvb_eeprom_read_size = <0x0>;|g\" tegra234-mb2-bct-misc-p3767-0000.dts",
"LINE=$(grep 'cvb_eeprom_read_size' tegra234-mb2-bct-misc-p3701-0002-p3711-0000.dts)",
"sed -i \"s|${LINE}|cvb_eeprom_read_size = <0x0>;|g\" tegra234-mb2-bct-misc-p3701-0002-p3711-0000.dts",
"LINE=$(grep 'cvb_eeprom_read_size' tegra234-mb2-bct-misc-p3701-0002-p3740-0002.dts)",
"sed -i \"s|${LINE}|cvb_eeprom_read_size = <0x0>;|g\" tegra234-mb2-bct-misc-p3701-0002-p3740-0002.dts",
"cd {{FILE_PATH}}"
]
It turns out that SDKManager generates .sh file in /tmp/ directory that contains the execBash values. I realized that there is the content of the execBash of the original json file in it, and I expect to see the content of my json file in it.
