Hi,
I would like to know, how to understand system hang during booting? When I search about it, I found NMI watchdog.

Hi mathew_k_t
for boot understanding one can follow Boot Chapter of Reference Manual,
check with jtag SRC_SBMR1,2 registers, test signals with oscilloscope and
use guidelines from link
I do not think that NMI watchdog can shed more light on problem.
Best regards
igor

Hi Igor,
Thank you for your response.
I think my question wasn't clear.
When I'm implementing the system as a product, there will not be any access to target console. Then, if the system fails to boot up or continuously restarting, I would like to indicate the user "system failed in Linux boot". So how I can understand the system failure without any access to kernel log.
Hi mathew_k_t
in application, when it successfully boot, you can add led as indicator.
Best regards
igor
