FDCAN bootloader in STM32G474RE

[Savan_Sutariya]

Hey, Is it possible to build a CAN-FD bootloader in STM32G474RE? @STTwo-32 @mƎALLEm

Hello @Savan_Sutariya 

According to the AN2606 and DS12288, the boot loader is located in the system memory. It is used to reprogram the Flash memory by using USART, I2C, SPI, and USB through the DFU (device firmware upgrade):

So, the FDCAN is not an option.

Best Regards.

Hi @STTwo-32 

Thank For fast Reply,

but According to AN5405 , STM32G4 series is supported for FDCAN bootloader.

Hello @Savan_Sutariya 

The AN5405 is for both Bootloader and open bootloader which is supported by the STM32G4 series. But the Bootloader is not available on STM32G4 series devices.

You'll have to code something that suits your needs, or pick a different device

Hi @STTwo-32 @Tesla DeLorean ,

Thank For reply,

Good day,

Is it feasible to develop a CAN bootloader from scratch?

 

[STTwo-32]

Yes, it should be. You just have to take a look at the AN5405 and other ressources available on the internet that should be helpful for you.

Best Regards.
