stm32F407 Discovery Board taking 2+ seconds to boot - SOLVED

Howdy all. I have a DIY rusefi ECU based on 407-Discovery board, and I noticed it was taking 2+ seconds to boot up before it started to try to sync/perform engine management actions.

after looking around, the solution is to solder SB10 solder bridge at the bottom of the board in the st-link area.
now it take 380 ms or so to start functioning.
