Hi pgo,

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.

Hi wang,

When using the debugger USBDM programs the security area to a default value to allow debugging.  It is a bit excessive and rewrites the whole 16 bytes to a default value of 0xFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFF.

Using the stand-alone programmer with "image" security option will program the image unchanged.

bye
