hello alberto18_90,
JP-4.3/r32.3.1 is really old release version, you may using the latest JP-4, (i.e. JP-4.6.5) release version according to JetPack 4 Reaches End of Life.
may I confirm which camera module you’re using, please also contact with camera partner for the JP-4 driver upgrade,
this issue will require our camera partner to do the support, let me add @xingxing here to help you.
