https://devzone.nordicsemi.com/f/nordic-q-a/82034/how-to-monitor-the-size-of-a-thread-stack-in-ncsIn 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.
