    PUART can't work until button 1 press twice?

      Hi, I'm facing a strange problem, an need someone's advise.

      I made a board using 20732S, keep button 1 and PUART schematic same as demo board.

      Test with hello sensor code, and button interrupt 1 works. debug trace log can be shown to HCI UART, but cannot show to PUART,

      where I've modified "spar_init.c" for controlling log output correctly.

      When I configure output to PUART, I found I have to press button 1 for 2 times, then PUART can output. The message can output until the button pressed twice, after that it output the log normally.

      Is there any suggestion for this issue? Thank you in advanced.
