Hi abdulwazeed1,
We do not currently support any optimizations for ARMv7. Would you like to open a feature request? Please send an email to support@wolfssl.com
Thanks,
Eric @ wolfSSL Support
Hello Lars,
That is an interesting use case. The library actually has a new ASN parser that can be enabled using
./configure --enable-asn=template
There are other options that can be enabled with the defines documented
in https://github.com/wolfSSL/wolfssl/blob … /src/asn.c
* WOLFSSL_ASN_TEMPLATE: Encoding and decoding using a template.
* WOLFSSL_DEBUG_ASN_TEMPLATE: Enables debugging output when using ASN.1
templates.
* WOLFSSL_ASN_TEMPLATE_TYPE_CHECK: Use ASN functions to better test compiler
type issues for testing
* CRLDP_VALIDATE_DATA: For ASN template only, validates the reason data
Mostly the ASN1 handling in the library is in the context of certificate handling, but maybe you'll find this extension callback example useful:
https://github.com/wolfSSL/wolfssl-exam … callback.c
Let us know if there are questions.
Thanks,
Eric @ wolfSSL Support
I reviewed this with the team, and this may have been fixed since the v5.1.1 release. Could you please test with the revision master from https://github.com/wolfSSL/wolfssl ?
A new source file was added,
/wolfssl/wolfcrypt/src/kdf.c
, and it is not being built by your VS project.
The VS project files in the repository have been updated in the latest release.
This is an informative error and it indicates that the peer has closed the connection and no more data will be expected.
I would suggest opening a support ticket by emailing support@wolfssl.com
MCPU is supported by arm-linux-gcc
https://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html
-mcpu=name[+extension…]
This specifies the name of the target ARM processor. GCC uses this name to derive the name of the target ARM architecture (as if specified by -march) and the ARM processor type for which to tune for performance (as if specified by -mtune). Where this option is used in conjunction with -march or -mtune, those options take precedence over the appropriate part of this option.
Hello rlev,
With wolfMQTT, you can change the broker IP during the network connect using
. If the client was already connected to a different broker, you would need to first need to disconnect (

Please try adding a CPU in the CFLAGS:
GENERIC EXAMPLE:

CC="/path/to/your/toolchain/toolchain-gcc" \

RANLIB="/path/to/your/toolchain/toolchain-ranlib" \

--host=<your host> \
<your other configure options here> \
CFLAGS="-mcpu=<your cpu definition here> \
<other cflags here>" \

Hi Galadrius,
wolfBoot does not support the Intel HEX format directly, but it can be easily converted to bin via objcopy:
e.g. on arm-cortex:
arm-none-eabi-objcopy --input-target=ihex --output-target=binary firmware_v1.hex firmware_v1.bin
Hi Galadrius,
I've moved this discussion to the wolfBoot sub-forum, as you were referencing the wolfBoot documentation:
https://github.com/wolfSSL/wolfBoot/blo … Signing.md
I'll check with the team to see what image formats are supported by wolfBoot.
Thanks,
Eric
Hi alen.loncaric
Thanks for contacting wolfSSL. Typically this is because the settings are not getting picked up by the configuration headers. Could you please share the "./configure" command you are using?
@adarshr.r6 and @SheilaLyons
We have some excellent CSR examples here:
https://github.com/wolfSSL/wolfssl-exam … er/certgen
If you still have questions, please feel free to email support@wolfssl.com to open a ticket.
Thanks for clarifying. I was able to reproduce a similar error
Creating certificate...
Failure code was -134
...with
./configure --enable-certgen --enable-certext --enable-certreq --enable-keygen --enable-debug
But with
./configure --enable-all --enable-debug
the example works correctly. I will work on updating the example instructions.

openssl req -in testcsr2.pem -noout -text

Try rebuilding the CSR without entering the unstructuredName field.
Hi adarshr.r6
Thanks for contacting wolfSSL. Typically we would like to review the problematic CSR. If you'd rather not share on this public forum, you are welcome to submit a support request by emailing support@wolfssl.com
Hi Bruce,
Thanks for sending a message to support@wolfssl.com. We will assist you there.

Hello Junkhar,

Hello Rod,
Please review the section on cross compiling in the wolfSSL User Manual:
https://www.wolfssl.com/docs/wolfssl-ma … users%20on
Let us know if there are questions.
Hi adarshr.r6
Thank you so much for reaching out to wolfSSL support, can you tell us a bit about what you are working on and the high-level overview of the project to help us better classify this inquiry? Thank you in advance!
Your application must include the wolfSSL configuration headers before any others.
https://github.com/wolfSSL/wolfssl-exam … -tls.c#L34
/* wolfSSL */
#include <wolfssl/options.h>
#include <wolfssl/ssl.h>
Let us know if there are questions.
Please try only creating a new SSL object, instead of a new CTX and SSL. Here is an example:
https://github.com/wolfSSL/wolfssl-exam … tls-perf.c
Your last message did not attach a pcap file
Could you share the wolfSSL configuration? Also a log and pcap is very useful in determining why a connection is failing. If you'd prefer to keep this information private, please feel free to open a support ticket by emailing support @ wolfssl.com
Have you run the example stand-alone yet? It might be useful to see it working first, then try to integrate.
