How to make an rt117x flashdriver

ywjack — Wed, 10 Sep 2025 10:11:41 GMT

Hello, NXP technical support

I'm currently working on an rt1170 UDS bootloader upgrade project. Since the flashdriver is solidified in Pflash, there might be security risks. Therefore, I want to create a flashdriver file, download it from the upper computer to the RAM of the rt1170 and run it, and then upgrade the program. But now I don't know how to make this flashdriver. Therefore, I would like to ask FAE if they can tell me how to make it, or if there is a DEMO project for making Flashdrives with rt1170. Could you provide it?

Thank you
