Hi again,

Check out using:

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

CONFIG_CONSOLE=y
CONFIG_UART_CONSOLE=y
CONFIG_SERIAL=y
CONFIG_PRINTK=y

Then the stack usage for all threads are printed.
