Please describe your issue below:

Hello, I want to use VIM3’s NPU on Android env.

Based on detect_code & model_code source codes in khadas_android_npu_library,
I compiled my network binary with Acuity 6.0.12 (ovxlib 1.1.34) and make JNI library with it.
(All libraries in npu app, such as libopenVX, libGAL,… are from GitHub - khadas/android_vendor_amlogic_npu -b khadas-vims-pie)

But when loading NPU application on Android, vsi_nn_CreateGraph returns null.
How can I check why vsi~ function returns null?

And in logcat,
v_gal HAL user version:
v_gal HAL kernel version:
will this issue(HAL patch version not matching) may cause ‘Failed to create graph’?
