Board crashes after upgrading libc6

Hi Team,

I am using the following Debian image (https://snapshots.linaro.org/96boards/dragonboard820c/linaro/debian/382/) in sd820 custom board. I did libc upgrade. Then the board is crashing once the booting process is completed. I am not able to access the system.
$ sudo apt-get upgrade libc6
Could anyone please give some pointers to find why this crash is happening.

Regards,
Ajith.
