If I buy a new STM32F303xC and solder it to my board, will it power up in DFU mode? Is it required to pull BOOT0 high to enter DFU mode? I would like to do first-time programming without manually using a jumper.
Have you read this document?
Pretty sure the F3 will expect you to pull BOOT0 High to enter the System Loader
Or you could use SWD/JTAG if you've wired that up.
I figured as such. I'll have to add a jumper or button. After application code is loaded I will have the ability to enter DFU from the program.
