Flashing the RT1064 with a new application

CK3 · ‎03-29-2021

Hi,

I want to use another computer model as a host to update the RT1064 with new binaries via the USB-OTG Port.

Right now my problem is that the board is booting from ROM (ROM-based bootloader), where I cannot communicate with it. I want to either allow the RT1064 to boot from Flash or from RAM.

The reason is that I need to flash the MCU Flashloader on the RT1064 so that it allows me to communicate with it, using a host computer and the MCU Flashloader API as in the Reference Guid (for example GetProperty command).

What is the best way to achieve this?

Hi,

You can use MCUBooUtility to communicate with the flashloader via USB-HID in serial downloader mode.

Have a great day,

Hi,

I am already using the MCUBootUtility tool. What I do is uploading a flashloader via this tool on the RT1064 and then reset it, switch to internal mode and try to communicate it via the MCU Flashloader command API. Unfortunately, this doesn't work.

What could I do?

Hi,

Please refer to this application note that provides an example of how to communicate with the flashloader.
