https://devzone.nordicsemi.com/f/nordic-q-a/15396/project-conversion-problem-51422ac---51822aaI have two board - 51422AC based PCA10028 and 51822AA based custom board. Custom board doesn&#39;t have 32768 OSC. My goal is to let custom board work with example project, &#39;ble_app_uart_loopback&#39;.
