How to install AML SDK to build aml_npu_app?

VIM3
1

I had downloaded Loading... to vim3 board.
in the build_vx.sh under each example, how to set the VIVANTE_SDK_INC and VIVANTE_SDK_LIB variable?
It looks like I need to install aml SDK. can anyone tell me where to install those hdr and libs?

Thanks,

@Tiger You don’t need to install AML SDK

Frank,
Thanks for reply.
in my VIM3 board, executing build_vx.sh will fail. I cannot find /usr/share/npu/sdk directory in my environment.
So I am confused how to set right path in the build_vx.sh if not missing SDK.

export VIVANTE_SDK_INC=/usr/share/npu/sdk/include
export VIVANTE_SDK_LIB=/usr/lib

@Tiger Please upgrade your system to latest release OTA version .

khadas@Khadas:~$ ll /usr/share/npu/sdk/include
total 20
drwxrwxr-x 5 khadas khadas 4096 Jun  8 05:55 ./
drwxrwxr-x 6 khadas khadas 4096 Jun  8 05:55 ../
drwxrwxr-x 2 khadas khadas 4096 Jun  8 05:55 CL/
drwxrwxr-x 3 khadas khadas 4096 Jun  8 05:55 HAL/
drwxrwxr-x 2 khadas khadas 4096 Jun  8 05:55 VX/
khadas@Khadas:~$

OK

Let me check how to do OTA upgrade.
I remember I install the system last week, and kernel is 5.12.0 already.

Thanks,

@Tiger Mainline firmware not support NPU , if you need to use NPU, Please use 4.9 kernel firmware.

yes. I turn to 4.9 kernel version firmware.
Now runing build_vx.sh, reports following error:

/usr/bin/ld: bin_r_cv3/main.o: in function draw_results(cv::Mat&, _DetectResult, int, int, det_model_type)': main.cpp:(.text+0x700): undefined reference to cv::rectangle(cv::InputOutputArray const&, cv::Rect, cv::Scalar_ const&, int, int, int)’

And the ld command already include those opencv libs as below:

Any idea about this this error?
