How to get and install pdk

i have installed the latest drive os and drive works on xavier,also i can build the sdk’s sample ,but i can not find the way to access the pdk and install it. how can i get the pdk and install it.

Dear @FYJ,
DRIVE OS PDK is not available via Devzone(developer.nvidia) release. Please contact your nvidia representative for PDK access. May I know why do you need PDK?

because i want to use the Nvmedia &SIPL framework

Dear @FYJ,
NvMedia and SIPL APIs part of DRIVE OS SDK already( https://docs.nvidia.com/drive/drive-os-5.2.6.0L/drive-os/#page/DRIVE_OS_Linux_SDK_NGC_Development_Guide/NvMedia/nvmedia_concept_nvsipl.html#)
