KBOOT for KDS3.2.0 with SDK2.0

Question asked by Didier JEANJEAN on Aug 30, 2019

I have to integrate a bootloader on a MK22FN512,

For an important finished application developed on KDS3.2.0 with Eclipse and SDK 2.0

I want to load application firmware via UART0 interface.

We bought 2500 parts MK22FN512VLH12 by CMS_INDUSTRIE


 Given the evolutions of the tools since KDS3.2.0, i would like to have clarifications on the following points: 


1) Not finding "Windows GUI updater application" for KDS 3.2.0 with SDK 2.0, the question is whether  it  is compatible with the latest proposed for NXPXpresso MCUBOOT? In other words, the remote loading protocol has not been modified since KDS3.2.0 ?


2) At “”                What are the different versions of:                   

         o FSL_Kinetis_Bootloader_1_2_0_KS22_1_0_0                   

         o NXP_Kinetis_Bootloader_2_0_0

The documentation explains the use but gives no compatibility information with existing tools like KDS3.2.0 and SDK2.0? 


3) I found the site “” planned for Kinetis bootloader v1.2.0 KSDKV1.2.0 and KDS v3.0.0,  while I'm using KDS v3.2.0 with KSDK2. 0 . Is it compatible ?


4) Is it easier to merge the boot loader with user code application project or manage it in another project? If i want to use step-by-step mode with the Eclipse GDB database in commit mode and not in debug mode.


Thank you in advance to the person who could inform us about this problem. Best regards from France.
