I made custom board with nPM1300 and nRF54L15 and now I'm thinking how to configure nPM. It is configureable through TWI inteface, but in all examples i saw that communication was through nRF5340 used as debugger (so from my understanding there is debugging firmware in that chip) and here is the question: can I configure it with external J-link device, or USB-TWI adapter, or do I need to buy nrf5340 DK only to configure my nPM? or could i use external J-Link with the onboard nRF54L15 to configure nPM?
