CAN bootloader of STM32F103RBT6 is not working

[kasun]

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

Is no CAN bootloader in STM32F103RBT6.

stm32F407 has:

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.

no, i never boot on CAN , only USB .

But there should be a way to do that. Anyway, thanks for the reply.
