Part Number:AM3352
Tool/software: Linux
Champs,
Customer reported the crash and I am able to reproduce it on BBB using the latest SDK (kernel 4.14). Steps to reproduce are as follows:
1. Boot the target with the OOB PSDK 5 SD card
2. Place a large (>60 MB) bin file on the target FS
3. Run:
root@am335x-evm:~# HMAC_KEY="12345678901234567890123456789012"
root@am335x-evm:~# FILE="xac"
root@am335x-evm:~# dd if="$FILE" bs=16 skip=3 2> /dev/null | openssl dgst -sha256 -hmac $HMAC_KEY -engine cryptodev| sed 's/^.* //'
after a few minutes run it crashes with the following trace:

I also monitored LowFree number in /proc/meminfo and it continuously decreases during the run and does not increase back even if I stop the the process before the crash. Customer is also suspecting memory leak.
Your insights are greatly appreciated!
