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 ?
