Hello,
I am quite new to NCS. I am trying to sending UART data from nRF52dk_52832 to PC.
The example is nrf\samples\peripheral\lpuart.
If I enable the example with CONFIG_LOG=y, the program crash with Stacking error (context area might be not valid)
I think stacking error should be the error related to memory so I have tried increasing memory size with CONFIG_MAIN_STACK_SIZE, CONFIG_HEAP_MEM_POOL_SIZE and CONFIG_LOG_BUFFER_SIZE but not working.
error message:

And advice is appreciated.
