@Frank I got the following output as seen below.
khadas@Khadas:~$ sudo find / -name "CLC"
[sudo] password for khadas:
find: ‘/sys/kernel/slab’: Input/output error
I did not make any changes to Makefile. Last week when I worked on this, I could generate the .so file, it’s unfortunate that now I am unable to generate that file.

I am using SDK Version 6.4.3 @Frank
Your system is already the latest one. Can you try our prebuild demos to check whether it works?
@numbqq I tried the inception demo and it works fine with me. But here I am not generating any .so or .nb file. I am using the current existing file in the demo.
In the demo when I tried working with detect_demo_picture, I got the following output:
Picture : khadas@Khadas:~/test/aml_npu_demo_binaries/detect_demo_picture$ sudo ./INSTALL
khadas@Khadas:~/test/aml_npu_demo_binaries/detect_demo_picture$ ./detect_demo_x11 2 1080p.bmp

det_set_log_config Debug
det_set_model success!!
model.width:416
model.height:416
model.channel:3
But, my question is last week when I tried to build my own custom model, i could generate the .so file.
I have not made any changes to the Make file or anything. Now, I am not able to generate .so file in bin_r directory.
Please see the output below:

Please help me with the same! @Frank
For the prebuild demo, please use the -h option to get the usage.
khadas@Khadas:~/detect_demo_picture$ ./detect_demo_fb -h
./detect_demo_fb: option requires an argument -- 'h'
./detect_demo_fb [-p picture path] [-w width] [-h height] [-m model type] [-f facenet flag] [-H]
For eaxmple, picture detect demo and display on fb:
$ ./detect_demo_fb -p 1080p.bmp -m 2
The usage changed. We will update the docs.
@Akkisony You must have some changes to the system, so suggest to reflash the latest image here: http://dl.khadas.com/Firmware/VIM3/Ubuntu/EMMC/VIM3_Ubuntu-server-focal_Linux-4.9_arm64_EMMC_V1.0.6-210520.img.xz
I have checked this image, I can build without problems.

@numbqq Please let me know when will the new document be uploaded. Also it would be great it you can give a detailed explanation on how to run MobileNet model on VIM3; just like yolov3 tutorial.
One topic for one thing. In this topic we only talk about the yolo model issue.
I have provided the correct usage for yolo picture detect above, please check whether it works for you.
$ ./detect_demo_fb -p 1080p.bmp -m 2
or
$ ./detect_demo_x11 -p 1080p.bmp -m 2
For other model, you need to convert them youself, you can follow the instructions docs from the SDK.
Hello, when using this version under Windows and using USB_Burning_Tool_V2.x.x.exe for USB firmware upgrade, do I need to unzip the file first?
@numbqq Thank you fro your help.
@Frank
I am getting an error for my custom model. Can you please suggest me what needs to be changed in order to overcome the error? I followed the same procedure as mentioned in the khadas website.
I have one doubt as my number of classes is 1, I have set the following parameters:
num_class=1;
coco_names[] = {“holes”};
I hope I have set the right parameters above. Please let me know if I am wrong.
@Frank @numbqq I decided to check and install the reuirements again to build the code using the SDK tool. During this process, I read in the document that, Python requires version 3.5.2. I got to know that in my system, Python version is 3.6.9. Does this cause any problem? Please find the attached screenshot.
If this does not cause problem, please let me know a solution for the above problem. VIM3 yolov3 convert issue - #39 by Akkisony
Thank you!
@Frank I can run the demo without any problem. After demo started to work, I have just started to follow your guide and I am trying to convert my own yolov3 model. I have replaced the .cfg file and .weights file and have followed every instrcution as per the manual. Yet, I am not able to use the NPU. 
Are my above two statements correct?
