My project requires that the ALSA driver be present in the kernel. Where may I find the kernel source files that correspond to the JP511-orin-nano-sd-card-image.zip?
For reference, the flash software can also create the SD card. Flash software though has the ability to also flash boot content stored in the QSPI memory on the Nano itself. JetPack/SDK Manager is the GUI front end for the actual flash software, and it is L4T which gets flashed (which is just Ubuntu plus NVIDIA drivers). The JetPack release is tied to the L4T release. You can find your existing L4T release with “head -n 1 /etc/nv_tegra_release”. Here are the URLs for looking up L4T and JetPack releases:
The docs for your release show some steps for cross compile from the host PC. The “Driver Package (BSP) Sources” contains an archive file, and the kernel source is an archive file within that archive file.

Hi,
The Driver Package (BSP) Sources for Jetpack 5.1.1 is
https://developer.nvidia.com/downloads/embedded/l4t/r35_release_v3.1/sources/public_sources.tbz2/
And please check developer guide for building kernel:
