Bootloader for K22FN256

[mpazzi]

Hello,

I have installed MCUXpresso 10.2.1 and downloaded SDK packet with mcu-boot item added.

But on my board I have MK22FN256 and not mcu MK22FN512 how is the only selectable from the SDK packet.

So, how I can modify the bootloader for the correct mcu ? Is it possible ?

Thanks for your support.

Hi Marco,

Since the only difference is the memory size you can just modify the Flash size in the memory
configuration editor to match the MCU you are using. 

Project Properties -> C/C++ Build -> MCU settings

Hope it helps!

Hi Carlos,

thanks for your repley.

On first time I have done that you saying, but it could not work correctly (error for missing some define or something else). So, I dezipped SDK module components and I found file for K22FN256 to substitute the K22F512 and I followed the procedure in chapter 9 of Bootloader v2.6.0 Reference Manual.

It has been laborius but at the end it work fine.

Thanks for your help.

Regards
