Topic: Stm32 WolfSSL

I am trying to implement wolfssl to stm32f4. I created stm32cubeMx Additional Software->WolfSS.4.7.0 into stm32f4 project.

And I select the Single Thread / no RTOS selection because my application not using FreeRTOS.

I want to using WolfSSL  with the LWIP library. I need to implement TCP communication like a server.   How can I start? because all examples about the FreeRTOS. I generated basic example with cubemx. But How can I use with source code. Code generated MX_wolfSSL_Init and MX_wolfSSL_Process functions but I cant see this function in libray.

And when I generated the source code from cubemx and created makefile. I have lots of error when I build.

build/startup_stm32f407xx.o: In function `LoopFillZerobss':
/home/tommy/Documents/WolfSSL_Example/startup_stm32f407xx.s:113: undefined reference to `main'
collect2: error: ld returned 1 exit status
Makefile:294: recipe for target 'build/WolfSSL_Example.elf' failed

Re: Stm32 WolfSSL

Hi Tomris,

Do you have a `main` function defined in your code? The `int main(void)` is an entry point required by the startup code. When you use the STM32 Cube back for wolfSSL it allows you to choose the wolfSSL/wolfCrypt features, but you would need to provide the code to call our API's. We have a wolfCrypt test demo that can be enabled also in the pack selections. What IDE are you generating code for? I have only tested with STM32CubeIDE, Keil and IAR.

You can find some great examples in this repo:
https://github.com/wolfSSL/wolfssl-examples

For LWIP we support their socket interface by default if you add `WOLFSSL_LWIP` to the generated configuration file `wolfSSL.I-CUBE-wolfSSL_conf.h`.

The documentation or the Cube pack is here:
https://github.com/wolfSSL/wolfssl/tree … /STM32Cube

Thanks,

Re: Stm32 WolfSSL

Hi Garske,

Yes I have main.c and also have "int main(void)", I generated from cubemx with makefile and I am using Visual Studio Code for the compiling the code. So I just give a "make" command to compile the file like an another stm32 project.

When I created project, I select all of them :

Re: Stm32 WolfSSL

When I generate the source code on cubeIde, I can compile but another Ide with makefile does not compile successful as I say before.

And when I generate the source code from cubeIDE, source code generated MX_wolfSSL_Init() and MX_wolfSSL_Process() function in main.c but these functions do not exist in library.

Re: Stm32 WolfSSL

Hi Tomris,

I have not yet tried using the "Makefile" code generation option in CubeMX with the wolfSSL pack. Can you share your Makefile as reference?

To work around this I suggest adding your own `MX_wolfSSL_Init` and `MX_wolfSSL_Process` API's that call `wolfSSL_Init()` and `wolfSSL_Cleanup()`.

Next time I am working on the Cube pack I will test with Makefile generation and see if there are improvements we can make.

Thanks,
David Garske, wolfSSL

Re: Stm32 WolfSSL

Hi dgarske,
I solved the Makefile problem for the stm32. When I generate the makefile and project, In the Third_Party/wolfSSL/IDE have also main.c. So I removed the main.c file in this folder. Than interestingly in the Src/main.c headers include false library decleration like this;

#include ".h"

I think its a bug when generated with cubemx. So I also remove this line than I can compile.

When I trying to write code in MX_wolfSSL_Init and MX_wolfSSL_Process proccess function I found an example in
https://www.wolfssl.com/docs/wolfssl-manual/ch11/ Documents.

When I add the "#include    <wolfssl/ssl.h>
" library as the example have. I got this error:

In file included from Middlewares/Third_Party/wolfSSL/wolfssl/ssl.h:149:0,
                 from Src/main.c:24:
Middlewares/Third_Party/wolfSSL/wolfssl/wolfio.h:157:36: fatal error: sys/socket.h: No such file or directory
             #include <sys/socket.h>

I stuck in there . Error is completely correct because In the Third_Party/wolfSSL/wolfssl does not have sys folder. How can I solve it ?

If I enabled HAVE_LWIP_NATIVE define, I get these error although I defined #include    <wolfssl/ssl.h>
#include <wolfssl/options.h>

Re: Stm32 WolfSSL

Hi tomris,

See https://github.com/wolfSSL/wolfssl/issues/4319
Similar report. Please try those suggestions.

Make sure `USE_HAL_DRIVER` is added to CFLAGS like "-DUSE_HAL_DRIVER" to include `wolfSSL.I-CUBE-wolfSSL_conf.h`. Also make sure you change you include so it does not use options.h and instead uses wolfssl/wolfcrypt/settings.h.

Thanks,
David Garske, wolfSSL
