STM32WB55 : How to flash the binaries for custom board ?

[Thomas Allain]

Hello everyone,

We are developing a custom board based on the STM32WB55CGU in my company, and I would like to know if the only way to flash the binaries for the CPU2 is by using the USB DFU bootloader ? Can we use a connection handled by a ST-Link ?

It is the case for the Development board and for the USB Dongle, so this is why I am asking.

You can expose the JTAG pins on your board and connect it to an ST-LINK.

On my boards, I expose the reset line, SWDIO, SWCLK and Ground and connect them to ST-LINK.
