Boot error after WDT reset

Hi all

Let me confirm about boot up.

There are following description in P1135 in reference manual.

After reset, the Boot ROM code determines that BT_FUSE_SEL
is blown (BT_FUSE_SEL = 1) and the ROM code performs internal boot according to the new eFUSE settings.

According to the description, after the reset since it is assumed that BT_FUSE_SEL = 1.

I know it follows OTP setting after WDT reset.

However, on the custom board, it goes to the serial downloader mode when trying WDT reset.

What should I check for it ?

Does the word "reset" in the description include WDT reset ?

Hello,

  Looks like internal boot with fuse configuration crashed, therefore internal serial

downloader starts. You may create request to get boot utility to review boot log.
