About Jetpack compatibility

[Hodu]

Hello,

When the binary built on jetson nano with jetpack4.5 installed is run on jetson nano with jetpack4.4 installed, the following error appears.
May I know what the problem is? Is backward compatibility guaranteed?

Thank you.

Hi,

No.
Would you mind compiling the binary on JetPack4.4 to see if any errors?
Since the GPU driver might be different across JetPack, it might not work if not compatible.

Thanks.

Hello,

As shown below, can the GPU driver be different even if the version of the jetpack component (cudam, tensorrt, opencv) installed in jetpack4.5 and jetpack4.4 is the same?
How to check the gpu driver?

Thank you.

Hi,

The GPU driver for Jetson is integrated into the OS.
You can find the OS versions between 4.4 and 4.5 are different.

• JetPack 4.4.1: r32.4.4
• JetPack 4.5.1: r32.5.2

Thanks.
