MBEDTLS_ERR_SSL_INTERNAL_ERROR while doing handshake on STM32 using coreHTTP with FreeRTOS about mbedtls HOT 3 CLOSED

Hi,

Given your modification of the code and it being on an unsupported platform, I really don't think I can help you here. The mailing list ([email protected]) may be of more help, but I would doubt it given again, your code and platform is pretty unique. Some hints on porting to bare metal can be found here : https://mbed-tls.readthedocs.io/en/latest/kb/how-to/how-do-i-port-mbed-tls-to-a-new-environment-OS/

The only thing I can suggest is attaching a debugger and determining where the MBEDTLS_ERR_SSL_INTERNAL_ERROR is being returned, which might show at least what has not been initialised or what has failed, as there could be any number of causes of this, from what you have provided there is no way I could determine that.

Hi Paul,
Thanks for your reply, I am getting this error from https://github.com/Mbed-TLS/mbedtls/blob/development/library/ssl_tls.c#L4545 from ssl_tls.c at the last step when I am trying to do a handshake.
I have attached my mbedtls_config file, if #I am misisng any configuration for this.

Ok.

First point, that line number does not return that error code, it calls mbedtls_ssl_handshake_client_step(), which really does not narrow things down at all.

I have seen your config, the problem here is that you are asking me to debug your code, which is something we are generally not going to do, and certainly not on an unsupported setup with modified code which we don't even have access to. That error code should not occur under normal situations, that either means you have not intialised something properly (unlikely) or some of your porting modifications are wrong (more likely).

If you have a reproducable bug on a supported system with a small reproducer, then please by all means open another ticket.
