Update firmware for MK20DN512VLL10 via CAN

huyho — Wed, 25 Jan 2017 07:19:29 GMT

We are developing a motion control board using MK20DN512VLL10, the original project is here.

We also used Processor Expert to create CAN module then integrated to firmware. CAN communication works fine.

We plan to update firmware via CAN, we connect a computer with a CAN controller software (ie. CANUSB ) to CAN bus, every CAN node will be received the firmware package and update automatically!

How should we implement? Thanks a lot!

Regards,

Huy.

Hi Vazquez,

Thanks for your response!

Can I stand in user application mode, receive and save firmware to flash or EEPROM (via CAN) then go to bootloader mode, copy the memory to correct user application place and run it (I think this method will be better for our target)? I am going to find a way to write my hex file to flash or EEPROM. Any idea about it?

Thanks a lot!

Huy.
