HI:

  I can run it successfully on the development board, but I cannot run it on the product board. The hardware difference is that the product board does not have an RTC crystal oscillator. Do I need to use RTC to run FlashLoader?

Hi,

flashloader is a MCUXpresso SDK apllication. You can download the SDK from https://mcuxpresso.nxp.com, see example project named "flashloader" and try to debug on your production board. You can customize it and replace the binary flashloader image distributed in MCUXpresso Secure Provisioning tool with your custom version.

About the requirements for the flashloader application, kindly refer to the description of the MCUXpresso SDK project.

HI：
Expert, I tried your method and ran it with SDK. The result is still the same. The development board is good, but the product board is not, and the simulation is not very stable. The code is quite large and the manual is not clear. For a while, I didn't know where to look for the reason. Is it a hardware issue? Or is it a software issue? Can you give some tips on where to start? thank you
