Boot error after WDT reset

ko-hey — Wed, 07 Jun 2017 04:54:22 GMT

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.
