title: Different Boot configuration from STM32G431
body: <p>My set-up is a custom board with an STM32G431, using keil as the IDE and Jlink as the Debugger, and the HAL Libary from STM.
  I need to boot my mcu with another configuration because I need the pin that's pulled on ground in the default configuration <a href="https://i.stack.imgur.com/Ghnv2.png" rel="nofollow noreferrer">Boot configurations, see reference manual s90</a>.My solution is to change the nSWBoot0 bit to 0 in the STM323G431xx.h. The Problem is to boot my setup on the MCU. If I download and verify, I can't get a good download. My solution is to use St Utillity with an StLink Debugger and change the bit there in the bit options. Do you guys know a solution without a STLink, preferred with a Segger product?</p>
