Hi Tushar,

Thank you for your reply.

Undefined symbols, but they are defined in standard libraries such as <stdio.h> and <ctype.h>.
I checked the source file and it instructs to include the above standard libraries.

The Undefind is appearing when linking the Ne10 library.
As I have not made any changes to the Ne10 source etc., it is probably a CCS setting or a problem when Ne10 was created.

The Ne10 library file was created using the DL from the following site and following the documentation in the DL file.

Follow the procedures in this library.

Hi Ito,

Have you added this library to the project configuration?

It may possible that the linker is throwing error because it could not find the library and unable to link the symbols.

Regards,

Tushar

Hi Thakur,

This is the linker library that was not displayed last time.

What specific steps do I need to take to debug?

And is there any other information you would like?

Best Regards,

Ito

HI Tushar

The same error was confirmed.

Hi Ito,

Can you please tell where the below functions are defined?

__fprintf_chk, stderr.

Have you included the stdio.h lib in the code?

Regards,

Tushar

HI Tushar

Defined in Ne10 library side.
NE10_init.c
NE10_boxfilter.neon.c

Yes, included.

Hi Ito,

Please provide sample code to replicate the issue at our end for further debug.

Regards,

Tushar

Hi Tushar,

I have sent you the project file in a private message, please check it.

Best Regards,

Ito

Hi Ito,

I have checked the project and it seems most of the error are generated from NE10_init.c.

Can you please check whether the stdlib.h file is included in Ne10_init.c file or not?

Regards,

Tushar

Hi Tushar,

The stdlib.h file was not included in Ne10_init.c, so it has been added.
However, the same error seems to occur.

Hi Tushar.

I have loaded the header files, but I get the error.
Libc.h is not standard in ubuntu, so I have to read all the header files that libc.h reads.

What is the environment used for FFT processing with NE10 on TI?
PC OS, CCS and other versions, CCS settings, choices made when creating the project (Select a board or device, kernel, compiler, keyword, categoly).

If you don't mind, could you send me the project file so that I can get Ne10 working immediately?

Hi Tushar.

The customer states that they have included the ctype.h file in NE10_init.c.

I am preparing screenshots to prove that I have included it.

Can you debug the project file I sent to private message previously?

E2E below describes the AM64 FFT.
What was the development environment and its version when TI checked the performance of the FFT?

The project only has header files for the library. Can you send me the source file also because the error are coming from the source files?

Hi Thakur.

Thank you for your help.

We have sent you the latest source files, please check them.

Hi Ito,

I have received the source of it but unable to build the library. Can you please share the steps to build it?

Regards,

Tushar

Hi Tushar.

The development environment is as follows.

K.Z said:

1. build NE10 using Ubuntu 24.02LTS on WSL2
　　・Install nix platform, cmake, gcc and g++.
       ・DL a clone of NE10 from Git.
　　・Execute cmake→make according to the documentation.
　　・The library libNE10.a is created.
2. Create ‘Hello_world’ in CCS. 
3. Paste ‘libNe10.a’ and the inc folder of NE10 into the project.
4. Register ‘libNe10.a’ in the linker library from the project properties.
5, Create the FFT section with reference to the NE10 sample.
6. Compile error

The build method uses Github.
See the URL below.

Hi Tushar.

If you are having difficulty building Ne10, can you tell us what environment you were in when you calculated the FFT data?

We prepare the environment.
PC OS, version of CCS etc., CCS settings, choices made when creating the project. (Select a board or device, kernel, compiler, keyword, categoly)

I don't have the above details. I will check this internally and let you know.

But my guess is the issue you are facing is not because of the Environment setting.

Tushar

Hi Tushar,

Thank you for your reply.

We have followed the instructions on Git hub but cannot build.
It would be very helpful if you could check Git hub and provide us with the project files.

Best Regards,

Ito

Hi Tushar,

Would you be able to receive information from Sitara team?

I don't know why I get an error if I have included all the files but the file is not defined.

Best Regards,

Ito

Hi Ito,

I am still checking the this. Have you also rebuilt the Ne10 library after including all missing files?

Regards,

Tushar

Hi Tushar.

Customers say they have included all of them.
At least, we have implemented the points pointed out by Tushar.
However, neither I nor my customers are familiar with Ne10 and CCS and we are not moving ahead.

I appreciate your help.

Ito

Hi Tushar.

How is your progress.
I'm sorry to bother you at a busy time

Hi Ito,

Apologies for the delay here. I am busy with some other escalation. You can expect a reply by monday EOD.

Thanks for your patience.

Hi Ito,

Thanks for your patience and apologies for the delay.

I was able to build the library on WSL with GCC Linux compiler, but not with aarch64 cross compiler. I am still figuring this out.

Meanwhile, I am also checking internally with the team regarding the environment setup used for benchmarking and will update you soon. 

Regards,

Tushar

Hi Tushar.

Thank you for your help.

If you can build it with the aarch64 cross compiler, could you please send me the file?
Thank you very much for checking your development environment.

Best Regards,

Ito

Hi Ito,

Thanks for your patience.

I have checked this internally and found that the Ne10 library was built on the EVM itself running Linux on A53 core.

For MCU+SDK, there is no documentation on how to build the Ne10 Library using cross compiler. I am still checking and will update you if I found documentation or able to build it.

Tushar

Hi Tushar

Thank you for your reply.

Yes, that environment is our ideal.

Tushar Thakur said:

Does that mean that an MCU+SDK is required to build Ne10 with an aarch64 cross compiler?

Hi Ito,

K.Z said:

Yes, the Linux uses it's own native aarch64-none-linux-gnu compiler to build the Ne10 library. In MCU+SDK applications we use the cross compiler aarch64-none-elf for compilation which will not be compatible with the libraries build using native Linux compiler.

Hi Ito,

Apologies for the delay here. The member who did the FFT benchmarking on A53 core running Linux was on leave. 

He will be back today, I will check with him for the steps to build it with cross compiler. I am still unable to built the Ne10 library.

Hi,

Apologies for the delay here. I have checked this internally with the person who built this lib for native Linux compiler.

He also has not tried building the library using cross compiler. I have checked the building steps on git also. It doesn't specify much detail on how to build the lib with Cross compiler.

The build issue you are facing might be coming because for RTOS examples we use cross compiler and the lib was built using native Linux compiler.

Currently, I am not able to build this with cross compiler and don't know how to proceed further without building the lib again.

Had the customer tried building the lib with cross compiler?

Regards,

Tushar

Hi Tushar,

Customers are unable to build lib with a cross compiler.
How did the person who ran the FFT benchmark build it using a native Linux compiler?
Is it really not practical to build with a cross compiler?
Is it possible to internally verify the solution?
If not, we must report this to the customer as soon as possible.

Best Regards,

Ito
