X-CUBE-SBSFU CAN bus support

Vadym · ‎2024-02-13

Hi everybody!

We have to implement firmware update feature via CAN interface. Our challenge involves implementing a secure and safe firmware update feature via the CAN bus, driven by regulatory requirements in the medical field. Unfortunately, the exact specifications are currently unknown.

I found X-CUBE-SBSFU and it seems like a great solution. However, I can't find any reference or example where X-CUBE-SBSFU is can be or used with CAN interface.

Is it possible to use the X-CUBE-SBSFU solution with CAN interface (by implementing "CAN loader" for example)?

Thank you in advance!

Hello @Vadym

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 :

Did anybody have experience using X-CUBE-SBSFU with CAN bus?

Hello, any update regarding this topic ?
@SofLit the same question was asked yes, but both are unanswered...

Hello @hpons

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)
