I am trying to compile wolfSSL from scratch in Vitis 2023.1 for a Standalone OS running on psu_cortexa53_0. I initially faced the "define versal" issue, but I managed to resolve it. However, now I am stuck with this error:

C:\wolfssl/wolfssl/wolfcrypt/port/xilinx/xil-versal-glue.h:29:10: fatal error: xsecure_mailbox.h: No such file or directory
   29 | #include <xsecure_mailbox.h>
      |          ^~~~~~~~~~~~~~~~~~~
compilation terminated.
make: *** [src/wolfcrypt/test/subdir.mk:20: src/wolfcrypt/test/test.o] Error 1
I have already enabled the xsecure library in the BSP settings, but I still get the same error.. I also tried regenerating the BSP, manually adding include paths.
If you found a solution to this issue, I would really appreciate it if you could share how you fixed it.

Thanks for the support. You were correct. It was the lack of "define versal". This has advanced me to the next error:

    make: *** [src/wolfssl/wolfcrypt/src/port/xilinx/subdir.mk:29: src/wolfssl/wolfcrypt/src/port/xilinx/xil-aesgcm.o] Error 1

The help files state a similar error could be caused by the failure to include xilmailbox. However, I have done that and when looking at the makefile can see its inclusion as noted below.

    psu_cortexa53_0/libsrc/xilmailbox_v1_2/src/Makefile psu_cortexa53_0/libsrc/xilsecure_v4_3/src/Makefile

Additionally, I have noted a few other issues.

1)  When using the standalone as the OS and attempt to change the lwip211 setting api_mode from RAW to socket it receive the following error:

    Error occurred while generating bsp sources for the domain 'standalone_domain'.
    Failed to generate the bsp sources for domain.standalone_domain

    Details: ERROR: lwIP with Sockets requires "xilkernel or freertos" OS

    ERROR: [Hsi 55-1545] Problem running tcl command ::sw_lwip211_v1_3::lwip_drc : ERROR: lwIP with Sockets requires         "xilkernel or freertos" OS
    while executing
    "error "ERROR: lwIP with Sockets requires \"xilkernel or freertos\" OS" "" "mdt_error""

    "::sw_lwip211_v1_3::lwip_drc lwip211"

    ERROR: [Hsi 55-1440] Error(s) while running DRCs.

2) If I switch the OS from standalone to FreeROTS (because standalone is proving so troublesome) the xilmailbox is not provided as a library to include and the build fails because it is missing.

I have tried to build the wolfssl code as s static library instead of including it in my primary application, but receive similar errors. I am using Vitis 2020.2 as my IDE and there is a lack of help for that specific version, but it seems like I should be able to work around it.

That said my primary concern is that neither FreeRTOS nor the standalone OS appear to be viable solutions because of errors 1 and 2 noted above, but I have been, perhaps foolishly, trying to get a build of the standalone OS using the api_mode of raw just to see if I could.

Thanks for sticking with the long post. Thoughts?

Check out the project instructions from the readme:
https://github.com/wolfSSL/wolfssl/tree … om-scratch

In particular, confirm that the preprocessor macro "WOLFSSL_USER_SETTINGS" is set, per step 15

Thanks,
Eric

Versal shouldn't be defined, but just to be certain I undef'ed it. Below is the current configuraiton of User_settings.h.

/* Xilinx SDK */
#define WOLFSSL_XILINX
#define WOLFSSL_ARMASM
#undef WOLFSSL_XILINX_CRYPT
#undef WOLFSSL_XILINX_CRYPT_VERSAL
#if defined(versal) && defined(WOLFSSL_XILINX_CRYPT)
#define WOLFSSL_XILINX_CRYPT_VERSAL
#endif
#ifndef FREERTOS
#define SINGLE_THREADED
#endif
#define NO_FILESYSTEM
#define HAVE_UINTPTR_T

/* Platform - remap printf */
#include "xil_printf.h"
#define XPRINTF xil_printf

#if !defined(WOLFSSL_XILINX_CRYPT_VERSAL)
/* Enable ARMv8 (Aarch64) assembly speedups - SHA256 / AESGCM */
/* Note: Requires CFLAGS="-mcpu=generic+crypto -mstrict-align" */
#define WOLFSSL_ARMASM
#endif

It appears the user_settings.h file is not being utilized by the complier; however, the compile time options appear correct:

06:16:56 **** Build of configuration Debug for project refdes ****

I assume I am doing something foolish, but I don't know how best to identify what that might be. I appreciate the help.

Is "versal" defined? Otherwise it looks like "WOLFSSL_ARMASM" is being defined at the end:

#if !defined(WOLFSSL_XILINX_CRYPT_VERSAL)
/* Enable ARMv8 (Aarch64) assembly speedups - SHA256 / AESGCM */
/* Note: Requires CFLAGS="-mcpu=generic+crypto -mstrict-align" */
#define WOLFSSL_ARMASM
#endif

I have toggled the defines both ways in the user_settings.h file. I am editing the file located IDE/XiLinxSDK folder. Perhaps this is the wrong file to edit.

Here the current contents are:

/* Xilinx SDK */
#define WOLFSSL_XILINX
#undef WOLFSSL_ARMASM
#define WOLFSSL_XILINX_CRYPT
#if defined(versal) && defined(WOLFSSL_XILINX_CRYPT)
#define WOLFSSL_XILINX_CRYPT_VERSAL
#endif
#ifndef FREERTOS
#define SINGLE_THREADED
#endif
#define NO_FILESYSTEM
#define HAVE_UINTPTR_T

/* Platform - remap printf */
#include "xil_printf.h"
#define XPRINTF xil_printf

#if !defined(WOLFSSL_XILINX_CRYPT_VERSAL)
/* Enable ARMv8 (Aarch64) assembly speedups - SHA256 / AESGCM */
/* Note: Requires CFLAGS="-mcpu=generic+crypto -mstrict-align" */
#define WOLFSSL_ARMASM
#endif

Thanks for joining the wolfSSL Forums. In your configuration, please ensure that either WOLFSSL_ARMASM or WOLFSSL_XILINX_CRYPT is defined, but not both.

Thanks,

I am attempting to compile WolfSSL within the Xilinx Vitis IDE for execution on a Xilinx board. I have followed the steps in the README under the IDE/XilinxSDK folder; however, at compile time I receive the following error.

"#Error can not use both ARMv8 and instructions and XILINX hardened crypto"

I have attempted to modify the user_settings.h defines to resolve this error, but have been unsuccessful.

Thanks,
Hodge
