Issue observed:
Go command on USB-DFU interface
: The user can not use Go command through bootloader on the USB-DFU
interface.
Proposed workaround:
Instead of the USB-DFU interface, the user can use JTAG or any other communication ports supported by the
bootloader to run Go command, like USART, I

C, SPI or CAN FD.

Boot from RSS
On STM32L562E-DK, the PH3-BOOT0 is fixed to a LOW level allowing the boot from the memory address
defined by SECBOOTADD0 option byte. In order to change the boot from RSS, it is needed to set the PH3-
BOOT0 to the HIGH level by removing R32 and soldering R31, or just by applying 3V3 on PH3-BOOT0 signal
between R32 and R31. In this second case, it is not necessary to remove R32 or to add R31.
explains how to easily connect 3V3 to BOOT0.
