Issue Description

Trying to install librealsense from source to solve pyrealsense2 issues. I accidentally deleted the rules file before so installing librealsense from scratch again. When trying to apply patched kernel module for Jetson L4T, I get the error "Unsupported JetPack revision 35.3.1 aborting script"

Based on Issue #11391 (comment), I need to match the supported JetPack version. Looking into the patch files, supported versions shown below.

Highest supported patch is 35.1 while I have 35.3.1.
Need suggestions on how to downgrade since there have multiple issues which say downgrading is not possible. Any help would be appreciated.

Hi @jidnyesha-patil You should be able to downgrade by flashing the JetPack using the Nvidia SDK Manager tool, as described at the link below.

Alternatively, you could build librealsense from source in RSUSB backend mode by including the flag -DFORCE_RSUSB_BACKEND=TRUE in your CMake build instruction. An RSUSB build of librealsense bypasses the kernel so that a patch script is not required.

Got it! I am trying the RSUSB backend mode first since I must get SDK manager to allow flashing JetPack.I am currently using the pre-flash SD card that came with the kit. Will keep this thread updated.
Thank you @MartyG-RealSense

@jidnyesha-patil Try to append "35.3.1" to "35.1", like: "35.1 | 35.3.1")

The RSUSB mode installation worked!

That's great to hear that RSUSB was successful for you, @jidnyesha-patil - thanks very much for the update!
