Moving to Nano forum.

Is the error observed after you install VPI 1.2.3?
If your Jetpack is 4.5.1, the VPI version should be 1.0.15. The VPI version on JP4.6.1(2) is 1.2.2, you may consider upgrading to JP4.6.1(2) if VPI 1.2.2 can satisfy your requirement.

好的，只是需要升级jetpack 是个大工程，我以为可以直接直接VPI这一个模块，如果不可以，只能通过升级jetpack的方法升级vpi到1.2.3了。
谢谢。

Hi,

The error indicates a compatibility issue.

NvMediaLDCUpdateTNR2Params is defined in the library that comes with the OS.
Please reflash the Nano and install the package from the same JetPack version.

Thanks.
