How to monitor the size of a thread stack in ncs?

[Deang]

In ncs1.7.1, I’m struggling with a problem about hard fault on nRF9160, but I have no idea to slove the problem.

nRF52840 transmits data to nRF9160 via UART0, the baudrate is 1000000 with flow control, After running a few minutes, nRF9160 crash.

The following pictures are the detailed error message.

I guess occurred stack overflow, but not sure. How to monitor stack usage in real time?

Here are the config options I typically use:

# Debugging configuration

CONFIG_THREAD_NAME=y

CONFIG_THREAD_ANALYZER=y

CONFIG_THREAD_ANALYZER_AUTO=y

CONFIG_THREAD_ANALYZER_RUN_UNLOCKED=y

CONFIG_THREAD_ANALYZER_USE_PRINTK=y

# add asserts

CONFIG_ASSERT=y

CONFIG_ASSERT_VERBOSE=y

CONFIG_ASSERT_NO_COND_INFO=n

CONFIG_ASSERT_NO_MSG_INFO=n

CONFIG_RESET_ON_FATAL_ERROR=n

CONFIG_THREAD_NAME=y

Hi Kenneth,

Thanks you.

I got the reason nRF9160 occurred crash, it was re-free memory.
