can not work with nrf54l15

Llama12580
I have customed a board based on nrf54l15.
Then I built the matter light_buld demo with target 'nrf54l15pdk_nrf54l15_cpuapp' and burned the file "merged.hex" into my custom board.
I successfully burned it into my board, but It didn't run. And I couldn't get any log through the UART(TX:P0.0, RX:P0.1).
BTW, I did these with ncs2.7.0.

    Hello,

    Can you elaborate a bit more what tests you performed?

    - For instance do other examples work?

    - Have you run radio test to verify that the radio and chip works?

    - Have you tried debugging through RTT using VS code or Ozone to observe where the program stops?

    - I assume you have tested with for instance v2.7.0-cs2?

    - Do you hardware have external 32kHz crystal? Is the UART RXD pin pulled high?

    Hi, thanks for your reply. I just wanted to confirm whether my custom board works or not.

    1. I also tried other examples, but I can't tell if it worked or not because I can not see any log. BTW, is it available to build project with target "nrf54l15pdk_nrf54l15_cpuapp" for my custom board?

    2. No, I didn't do any radio test.

    3. I did try to debugging through RTT using "J-Link RTT Viewer V7.88j", but it doesn't have nRF54 target. I didn't see any log ,whatever using RTT viewer or using UART30(TX:P0.0, RX:P0.1).

    4. No, I have not tested with v2.7.0-cs2, would it be better than v2.7.0 (commit:5cb85570ca43bc344d3145c2338128eacf4b48ec)?

    5. Yes, my hardware have external 32kHz crystal, but I am not sure whether the UART RXD pin is pulled high or not, which pin and how should I check?
