Question

CAN bootloader of STM32F103RBT6 is not working

Hi ST team,

I'm trying to upload a new code to the STM32F103 via CAN tx/rx. I set the device to boot mode, BOOT0 = 1 and BOOT1=0 (system memory).

I sent a CAN frame via CAN tx/rx, but I didn't get any response from the STM32 CAN bootloader.

Is it possible to do this?

Is there a CAN bootloader in STM32F103RBT6?

If not, please suggest me any other model of STM32 for this project.

Thanks,

Kasun

    Thank you for the information.

    could you please show me the way of uploading a new code to STM32F407 via the CAN port?

    It will be much helpful if you can provide me detailed process.
