STM32Cube Programmer API USB Example error

[Gabriel T]

Hello,

I put my STM32H743XI in Bootloader mode and launch STM32Cube Programmer USB example on VS and got :

I have two question :

• Where does this error comes from and how to fix it ?
• Can I skip option bytes programming and still flash my MCU ?

Regards

Are you talking about the warning on BOR level not being updated ?

If so, it is not an error and you can skip it if you don't need to program the BOR Level.
