[STM32G071EBY6] Where to get the STM32 bootloader sample codes and do customization

[Alex_Liang]

I'm a beginner for MCU developmenet and am developping a product with STM32G071EBY6, and wanna make it support the USART2 to upgrade firmware. But seems needing bootloader customization.

 

But I didnot find where to fetch the sample codes, and also nowhere found some guides.

 

Ask for help!!!

 

Best Regards!
