LPC54608 mbedtls porting

ruiwangm — Fri, 02 Feb 2018 03:57:43 GMT

Hi,

Is there any samples about running mbedtls on lpc54608, and lwip? I would like to implement a https client, and did some work on it, now it can compile successfully, but always get a failure on handshake, as I am not familiar with the ssl connect, it takes time for me to debug deepper.

Best Regards,

Rui

Hi rui wang

Thank you for your interest in NXP Semiconductor products and

the opportunity to serve you.

Unfortunately, SDK library hasn't included the mbedtls demos until now, for understanding mbedTLS, please referring to mbed TLS tutorial - Knowledge Base

Have a great day,
TIC

Hi Jeremy,

Thank you for the response, I have ported the mbedtls to my project, and it compiles successfully, but unfortunately, it's always reset by the server at the handshake stage, or sometimes after handshake and while reading the ssl content (it works with the same code on windows, also maybe because of the different platform configuration). I am still working on it.

Another observation is, the ssl handshake procedure goes very slow(too slow mips?), it lasts more than one minutes, I am wondering if this is the root cause.
