Hi,

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 ?

Thanks,

Devi Pandurangan
