Jetson Xavier NX Memory map

[dks338]

Hello

i’m using xavier nx on my own product.

and i’m going to get a certificate called IoT Security Certification in Korea now.

The certification has following requirements.

Memory map image(or text) for Xavier NX CPU (Kernel)

I tried to find it in various documents, but couldn’t find it.

Where can i find it?

I will attach an example of a memory map as an image.

Thank you .

Hi,
If you use Jetpack 4 release, we use NvBuffer APIs for accessing frame data. The data can be captured into NvBuffer and call NvBufferMemMap() to get CPU pointer.

Thank you for your reply.
Unfortunately, I used Jetpack 5 release.
In Jetpack 5, Can i NvBufferMemMap() too?

Hi,
We have switched to NvBufSurface APIs on Jetpack 5. Please check the header files:

/usr/src/jetson_multimedia_api/include/nvbufsurface.h
/usr/src/jetson_multimedia_api/include/nvbufsurftransform.h

You can call NvBufSurfaceMap()
