Compiler get stuck in side nrf_crypto_hash_update() function

[R_S]

Hi i am using nordic nrf52840 chip. and SDK17.1 i am using.

in that under secure bootloader code i am trying to use the nrf_crypto_hash_update() function to calculate the hash of my application code.

But when compiler reached to this function then it got stuck somewhere. 

Any idea y this happened. is i need to enable something in the code for hash calculation...?

Hello,

Could you please take a screenshot of the CPU registers and dissambly view when the program is stuck? Also, are you calling this function directly, or via the nrf_crypto_hash_update() function like how we do it in nrf_dfu_validation.c?

Best regards,

Hi,

find the below screen shots.

Thanks, so the program looks to hanging inside the crypto runtime lib waiting for a cc310 interrupt. Are you calling this function in a critical section which may block the cc310 interrupt from coming through? Also, were you calling nrf_crypto_hash_update directly, or is it invoked via the nrf_crypto_hash_calculate() function?

I am calling this function directly after nrf_crypto_hash_init() function

Are you calling it in a critical region? Can you post the code here?

And also i doing the same thing in open bootloader code also, but in that i am not facing such an issue.
