Hi Ajmal,

I recommend to check the location of the zephyr kernel.h header file. The Zephyr header files were rearranged a bit over versions. For example:

In Zephyr 3.4:

$find zephyr/* -name "zephyr.h"
zephyr/include/zephyr/zephyr.h
$find zephyr/* -name "rand32.h"
zephyr/include/zephyr/random/rand32.h

In Zephyr 2.7.4:

$find zephyr/* -name "kernel.h"
zephyr/include/kernel.h
$find zephyr/* -name "rand32.h"
zephyr/include/random/rand32.h

You might need to update the wolfssl module include paths for zephyr header files.

For example I needed to make these changes for Zephyr 2.7.4:

diff --git a/wolfcrypt/src/random.c b/wolfcrypt/src/random.c
index 5187334..9dcb8eb 100644

I didn't need to do this for the Zephyr v3.2-branch that I pulled, but maybe your version is different.

Hi Ajmal,

In your wolfssl_test/prj.conf try replacing 

COMMON_LIBC_MALLOC_ARENA_SIZE

with 

MINIMAL_LIBC_MALLOC_ARENA_SIZE

The COMMON_LIBC_MALLOC parm is recent to Zephyr 3.4, but doesn't exist in older Zephyr versions. (our wolfSSL Zephyr samples were written for Zephyr 3.4).

After updating the parm all four of the examples worked for me with the Zephyr 3.2 branch. I attached a small patch to apply if that's handier.

Let me know if this helps!

Edit: the file didn't attach. Here is the git diff:
