Hi all,I'm creating a personnal board with an STM32L432 mcu, but I have a question about BOOT0. I'd like my futur to give the possibility at my futur clients to update the board. To do thaht I know I can use DFU mode and to enter to this mode BOOT0 s...
Could you please give me an IBIS model of STM32U4R9AII6U
