MSP432E401Y: ARM mbedTLS

Devi S

Part Number: MSP432E401Y

I’m trying to integrate NXPs secure element SE050 into an application running on MSP432E401Y chip.

I was able to successfully integrate their middleware(Plug and trust) on a baremetal project with mbedTLS enabled.

It seems on this baremetal project, entropy_source (from entropy_alt.c) is not working. And this has a knock on effect on mbedtls_ctr_drbg_seed function which fails and takes the entire project down with it.

Also, from the sole example given in the Simplelink SDK (tcpechotls), I see that mbedtls is used in a project with RTOS enabled.

Should I try integrating this code in an RTOS based project and check? Has anyone worked on this ?

Do you have the source demo code from NXP for SE050 host? And the document?

Yes. I do have the Plug and Trust middleware code which contains demo code for SE050. The middleware code I’m trying to integrate is taken from LPCXpresso55s69 code generated from the NXP website.

As regards to their documents I have gone through their application notes and datasheets.

At present I have got “se05x_Minimal” example from their demos on my MSP432E4 based board. This version of code does not use mbedTLS.

Not familiar with the demo code from NXP, but if how any issue about how to use MSP432E or CCS I can help with that.
