FDCAN bootloader on UFBGA169 STM32H743AI

[DrDro]

Hi,

App note AN2606 says I should use FDCAN1_Rx pin PH14 (similary Tx pin) to be able to use FDCAN bootloader but selected package UFBGA169 doesn't have such pins.

Can I use default FDCAN Pins to work with bootloader?

For STM32H743, you can activate the FDCAN bootloader with only by PH13/PH14 pins.
