Secure Firmware Update on a Mass Production Board Using RT1064

[kbsidi]

We have developed a mass production board using the RT1064.

The Boot Mode Switch is fixed to 0x0010.

We would like to implement firmware updates with the Secure feature applied.

Could you please let us know if this is possible, and if so, how it can be achieved?

Hi @kbsidi ,

Thanks for your interest in NXP MIMXRT series!

Your application scenario is feasible and you are advised to refer to the OTA related project in the SDK. It uses imgtool to sign the image and then performs an OTA upgrade over the network. Also, SBL and SFW are good reference projects and you can find them on github. https://www.nxp.com/docs/en/user-guide/MCUOTASBLSFWUG.pdf

Best,
Gavin

My custom board does not have wireless communication capabilities.
I would like to know if it is possible to implement this using a USB-based method.
Thank you.
Alex.

Yes, using USB is also possible. You can check out the usb_dfu project.
