Topic: [SOLVED] RSA_FUNCTION MP_EXPTMOD_E: memory/config problem error
Hello:
I'm using wolfssl stack with Atmel ATECC508 crytochip.
I 'm getting this error when trying to verify vertificate signature;
About to verify certificate signature
[b]RSA_FUNCTION MP_EXPTMOD_E: memory/config problem[/b]
Rsa SSL verify error
Confirm signature failed
Failed to verify CA from chain
.......
About to verify certificate signature

wolfSSL Leaving DoHandShakeMsg(), return -188
wolfSSL error occurred, error = -188
ERROR: aws_client_mqtt_connect L#244 Error(8) : Failed to TLS connect!
It's clear there is a memory problem, but I would like to know how much memory is required for this operation. I tried to add more memory to the heap (using FreeRTOS) but it didn't help.
Any other advice about how to solve this issue?
Thanks in advance
Gus
