Hi Kaleb.

Yes, I´m using the largest possible heap, which in my case is 32768 bytes.

I will try with these options to see if I get different results.

Thank you!!

Hi Kaleb.

After enabling SHA512/SH1384, I got the following error:

RSA_FUNCTION MP_EXPTMOD_E: memory/config problem
wolfSSL Leaving ConfirmSignature, return -155l

According to the post at https://www.wolfssl.com/forums/topic110 … rror.html, it's necessary to change FP_MAX_BITS directive to 8192. After this, I got the out of memory error:

wolfSSL Leaving ConfirmSignature, return -125

I guess there is nothing else to do with this hardware. I have to use a more powerful microcontroller.

Thank you anyway for the great support!!

Cheers

Hi Kaleb.

Sorry for the trouble.

The NO_SHA directive isn't defined. However, in a debug session, stopping the execution at the beginning of HashForSignature function, I noticed that the sigOID parameter had a value of 0x00000290, which stands for CTC_SHA384wRSA (decimal 656), according to definitions in asn_public.h file. In this way, should I enable SHA384 in my configurations?

The debugging results are attached.

Thanks in advance.

Hi,

I tested with the certificate you sent me. I noticed that using it there was possible to decode the certificate policy. However, I got the same (-188) error, as shown below:

Hi Kaleb.

First of all, thanks for your reply.

Yes, I have a file system available in this hardware. I'm reading the certificate file from a SD Card.

The server name I'm trying to connect is monipark.com.br

Attached, the certificate file I'm using.

Best regards.

Hi all,

I'm trying to use WolfSSL with the LPC1768 microcontroller.

The ecosystem looks like below:

  • IDE: uVision5

  • Operating system: FreeRTOS

  • TCP/IP stack: FreeRTOS TCP

  • Device: NXP LPC1768

  • WolfSSL version: 4.0.0

I'm getting -188 error in handshake process, according to the Debug output, below.

Has anyone succeeded in using the library with this or an equivalent device?

Could I get some help with the parameters for this specific use case?

Attached, the user_settings.h I'm using.

Any help would be appreciated.
