Watchdog resetting board discof746ng


DISCOF746NG board is getting reset by watchdog after every second.The board was working fine up until a week ago.
We were working on capturing and sending 160*120 resolution image via http and also writing this image buffer to a file with qspif block device.

How to check why the board is being reset by watchdog?
Is it possible to bring the board back to working condition?

Steps tried out so far :

  1. Full chip erase
  2. Firmware upgrade

serial connected to windows system

Can you share some code?

Hi @ladislas,

The issue has been resolved by setting few option bytes to default setting using stlink.
