FDCAN Bootloader for STM32G0B

Pooja321 · ‎2024-03-28

I did not find any solution of Bootloader for CAN2.0A or CAN2.0B with SMT32.

Currently i am using below part no.

MCU-'STM32G0B1CCT6'

CAN IC-'ISO1044BD'

Sorry I wasn't very attentive.

Meanwhile, he didn't mention the usage of CubeProgrammer. Moreover he is planning to use CAN2.0A or CAN2.0B which is not available even on STM32G0B1 devices (see AN5405).

Regarding the support of FDCAN on CubeProgrammer, see this thread.

Seems there will be a support of FDCAN bootloader on CubeProgrammer. But I don't have a visibility of the plan.

Hello,

According to the application note AN2606 STM32G0B0 devices does not support CAN bootloader. You need to develop your own bootloader.

The questinon was for the STM32G0B1! There is a FDCAN bootloader in the boot rom of the STM32G0B1 series. You have to connect the CAN-Bus driver to PD0 and PD1. But ST don't have any meaning to used the FDCAN booloader (STM32CubePorgrammer has non FDCAN support). You have to make Your one application to program the MCU via FDCAN.
