8 Build Linux Vision SDK File System

From Vision-SDK 3.4, there are changes in the file-system build to enable a smaller file-system. While the file-system provided as part of the Processor-SDK Linux automotive is ~700MB, the file-system as part of Vision-SDK release is ~60MB. This reduction in size is achieved by removing components not required for traditional ADAS use-cases.

Follow the instructions below to rebuild the Vision-SDK file-system:

  1. Build the Yocto file-system by following the instructions as part of the Processor_SDK_Linux_Automotive_Software_Developers_Guide wiki.
  2. Apply the patches present in the linux-kernel-addon/fs-patches/yocto/meta-glsdk folder of Vision-SDK to the tisdk/sources/meta-glsdk folder in the yocto repository.
  3. Apply the patches present in the linux-kernel-addon/fs-patches/yocto/meta-arago folder of Vision-SDK to the tisdk/sources/meta-arago folder in the yocto repository.
  4. Rebuild the file-system by running the bitbake command as documented in the Processor_SDK_Linux_Automotive_Software_Developers_Guide wiki.
  5. The changes in meta-arago are for the reduction in file-system size while the changes in meta-glsdk are for the VDRM and VDRM+ IPUMM-based decode.
