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?
