Hi all,

I'm facing the problem of unexpected behavior (mostly system freeze) when trying to initialize secure pRNG (Fortuna) with:

wiced_crypto_use_secure_prng()

Environment:

1. SDK 6.2.0.72

2. HW: ISM43903 module

In my case freeze happens when SDK is internally calling:

wiced_hw_sha256_starts()

Looks like more or less memory leak, but I might be wrong (didn't trace it carefully).

I saw that since SDK 6.1.0.85 introduced (enabled by default) alternative crypto functionalities basing on HW (eg. sha256_alt.c etc.).

Disabling usage of HW crypto alts fixes described problem:

GLOBAL_DEFINES += WICED_CONFIG_DONOT_USE_HW_CRYPTO

Is it possible to use HW crypto functionalities using 43903 platform and SDK 6.2?

Did you try using the test.console app or some other application?
