Hello @Devank_J

Sorry for the delay.

A ticket is submitted internally to provide either example of guidelines how to support CAN.

Ticket number (Ticket 202646: stm32H743 SBSFU through CAN Protocol guidelines ?) (This is an internal support Ticket for Tracking not usefull for you)

Best regards

Hello @Devank_J

According to information I get from technical expert, it is possible to use the X-CUBE-SBSFU solution with CAN interface. This will consist in replacing the UART YMODEM solution by a CAN solution.

Unfortunately, only the UART YMODEM solution is available and no demo planned to support other interfaces in short-term.

Here are the files which may be impacted in order to change from UART to CAN:

At SBSFU (local loader) :

Or at UserApp level:

Or at the « standalone loader » level when it is used :

Best regards,
