I don't have a clue. I paste the mem file and the lcf file here, actually, these two files are included in the fNET 2.7.5 source package, they should be fine. And it works well if I use Multillink, but if I want to use Jlink, I have to deselect the option "uninitialized data" as I have mentioned above. I really want to find out the root cause for this issue to avoid potential risk for my project.

// Memory Configuration File
//
// Description:
// A memory configuration file contains commands that define the legally accessible
// areas of memory for your specific board. Useful for example when the debugger
// tries to display the content of a "char *" variable, that has not yet been initialized.
// In this case the debugger may try to read from a bogus address, which could cause a
// bus error.
//
// Board:
// Kinetis K60FN1M0

// Reference:
// -
// All reserved ranges read back 0xBABA...
