I have just purchased nRF54L15 DK, run Quick Start and programmed 'Hello World', but the verification failed and nothing happened. I opened the serial terminal, but nothing happened there either.
What is wrong? Is there any way to get it to work? Is it a failure of the hardware or bootloader?
Attached is the log.
