AN3966 over DevKit407 (STM32F407G-DISC1 + STM32F4DIS-BB) with TrueSTUDIO (Atollic)

Hi All,

I have a DevKit407 (STM32F407G-DISC1 + STM32F4DIS-BB) and I'm working with AN3966.

I'm using the newest version of TrueSTUDIO

Exactly, I'm trying to run httpserver_socket (with FreeRTOS) over Board.

I know that there are a lot of threads about this topic, but I can not get to run it.

My problem is that app not compile. After import project from source code examples of AN3966 (stsw-stm32070), when I try to compile the IDE said some files are not found.. for example:

..\..\..\..\..\..\Utilities\Third_Party\lwip-1.4.1\src\core\ipv4\inet.c:41:23: fatal error: lwip/inet.h: No such file or directory

But the code is just imported from example...

I tried to modify the MCU the exact model, but I got the same error.

And, I tried to make a simply led blinking from STm32CubeMX and it works.

I think that it has to be a 'easy' step, simply run a example, so I think that maybe I'm skiping some step.

Please can you help me?

(Sorry if the solution is already posted, but I found for a lot of hours, and I didn't find the solution)

Thanks!

Jordi

The F407 Discovery itself has no Ethernet, so ST's Firmware package has no ..\Utilities\Third_Party\lwip-xxx sources.

There is a firmware package for the STM32F4DIS-BB board, downloadable somewhere on the Element14 webpage.

Pretty sure you can find it yourself.

Last time I tried the ethernet/webserver example from that package build 'out of the box'.

Dear AvaTar,

thanks for your feedback.

But, I have full source code for lwip-xxx. I can see all files.

I downloaded the example from

https://www.st.com/en/embedded-software/stsw-stm32070.html

Furthemore, when I follow the error that shows the console I can open the file that compiler says 'not found'.

So, I think it's a problem of include path in example, but I don't understand. It's a ST official ApplicationNote, it has to be 'plug&play'.

Someone check AN3966 over F407Dis with TrueStudio (Version: 9.0.1 Build id: 20180420-1214). I'm work over Win10

Thanks

Jordi

Does it come with a project/workspace for Truestudio ?

I guess you expect a bit much here ... ;)

Adding an include path is a simple exercise. I use Crossworks, wich has no 'out of the box' support from ST. For porting aproject, I always spent the first 15 minutes assembling the source files, include paths and link libraries.

Yes, the example has a

TrueSTUDIO project file.

I have reach to compile the source, the 'error' was at import project. I did Import from 'Existing Projects into Workspace' and I didn't reach to compile. Now I import the project as 'Projects from Folder or Archive', so I can import and compile the file. (And, I think TrueSTUDIO has some problems with linked files....)

Only I need to modify a timeval include struct (it is documented in the code), to use the private definition or the same of system.

Now the code compiles, but it doesn't work. I think that I understand 'the problem', the

example is not ported to DevKit407, and when I change platform in TrueSTUDIO, the example not has under ifdef the pinouts.

So I think the problem is 'solved'.

Thanks

Jordi

The awkward project import is one of the weak points of Eclipse IMHO.

And many paths (sources, include, libs) are expanded using Eclipse-owned shell variables, with unclear project inheritance.
