HI ,

One of our BMS customer using S32k344 has the following issue

I am using the crypto_1 mcal to do hashing. For some reason, when I run the job, the hash buffer is does not get filled in at all and just stays with whatever was in it before.

Hi @adijoshi 

Is the hash buffer forced to non-cacheable RAM? All data objects used for communication with HSE must be forced to non-cacheable RAM. HSE can't see the cache. Or you can simply turn off the data cache to see if it makes a difference.

Regards,

Lukas
