I find a question of usbdm.
my project for test is in attachmpent.
In my project i place some variable in 0x400 that is flash confuration field in kl05z32.
when i use USBDM to debug the project,I can't find my data in 0x400.
But I find my data in 0x400,when I try to use jlink to debug my project.
I think you forgot to program flash confuration field in flash.
