RTOS/PROCESSOR-SDK-AM335X: SSL package

Christopher Weber

Tool/software: TI-RTOS

I have searched and found that there is (or was) a lib that works with the smaller IP stack on the C3200 devices.

Is there a package to implement SSL with the NDK?

In the Windows and Linux world, I have written a HTTP web server, which ports over to the NDK using the BSD sockets. And in the Windows and Linux world, I also easily implemented the SSL API into the same server, making it HTTPS, using OpenSSL. But looking for an SSL solution in TI/RTOS NDK now.

So, do I need to take on the task of attempting to port the OpenSSL over to run in a CCS project, or is there a package already out there somewhere which I haven't found yet?

My target is the AM335x, and I'm currently prototyping development on the BBB. (CCS 7.2, pdk_am335x_1_0_7 Apologies if I over "tagged" this )

Thanks.

The RTOS team have been notified. They will respond here.

Chris,

There are a few SSL packages (wolfSSL, CyaSSL, uSSL) with NDK/TI-RTOS on MCU device, but not on AM335x yet.

You may contact these package vendors to evaluate the porting effort comparing with OpenSSL.

Garrett,

Thanks. I will take a look at them, and see if they are more friendly to porting to RTOS.

One problem with CCS is that you can't simply import the SSL structure. Every directly has files in them that are not related to the module, they are just unit tests, intended to be run as standalone programs. Each directory has it's own makefile which list only the sources used for that module. I import the folders, and CCS complains about there being about 20 occurrences of the function "main() " It means systematically going through each makefile, to determine which files are used, and any specific flags that make apply. No small task.
