AES CBC with nRF52832 using NCS

Hello,

I'm using nRF52832 custom board with nRF Connect SDK2.6.0

When I try to run AES CBC sample from ncs\v2.6.0\nrf\samples\crypto\aes_cbc, 

I got an error log:

*** Booting nRF Connect SDK d96769faceca ***
[00:00:00.382,934] <inf> aes_cbc: Starting AES-CBC-NO-PADDING example...

[00:00:00.382,965] <inf> aes_cbc: Example exited with error!

But when I run the same application code build for nRF52840 dongle, it workrd.

How do I fix the code for my nrf52832?
