I am porting the mbedTLS library into my Keil v4 bare metal project using the LPC3250 Arm9. My project does not have an operating system, therefore I cannot use net_sockets.c or Default entropy sources. I am following the link below but need help with adding a new entropy-collection function. My goal is to use mbedTLS to send TLS secure emails from my embedded system.
So far I have moved over all the source and header files into my current Keil project but am now stuck on the networking and entropy part. I want to use the mbedTLS ssl_mail_client example to set up a SMTPS function.
Has anyone successfully imported mbedTLS into their bare metal, no OS, embedded project? Are there any examples of bare metal networking or entropy C code? Any help is appreciated, thanks.
