you don’t need it. If there’s a boot loader on the pcb the end user can flash it in Vesc Tool or FocBox Tool or BLDC Tool.

The bootloader gets programmed into the micro
oh I thought it was standard shit that came on the chip from the factory. my bad.
You know, I think you can get chips preprogrammed from some suppliers, so that actually may still be an option lol
We program all STM chip before make assemble.

No, you are correct. There is this thing called the “Device Firmware Update” that no one seems to want to use!
Vesc tool has no support for STM32 native DFU.

From factory is ok. But need to enable DFU by short pin on PCB. Then can flash use STM tool. But for mass production is better for flash before SMT or making jig for flash.

I was planning on connecting a DIP switch to the boot pin, and then using the USB DFU, as the connector for that will be populated for normal operation anyway.
But first choice will always be having the distributor, such as digikey, preprogram the chips for me.
