RTOS_SDK_1.5 MBEDTLS ISSUE

Postby gustavomassa » Tue Feb 07, 2017 1:57 pm

Hello,

I'm using mbedtls to connect to aws iot, but I'm not able to compile the code since the mbedtls is missing some defines..

I'm using the original libmbedtls.a from the ESP8266_RTOS_SDK 1.5, I tried to edit the config.h but it dosen't matter, I really need the source code of mbedtls to re-compile it using the necessary config.

Code: Select all

/root/esp-open-sdk/ESP8266_RTOS_SDK/lib/libmbedtls.a(ssl_tls.o):(.text.mbedtls_ssl_fetch_input+0x4): undefined reference to `max_content_len'


This is the correct config.h:

Code: Select all

Any thoughts?

Thanks :D

Are you able to compile the mbedTLS sources?
