I'd like to develop my own dev/debug app to load on the debug K20 on the FRDM-LK25Z.  What's the memory map for image files loaded by the debug bootstrap code?

Specifically, I'm looking for the information needed to make a loadable debug app:


  • The starting address for the image (i.e. where it gets loaded in flash)
  • The boot entry point address
  • How/where interrupt vectors are handled
  • Ranges of flash and RAM available to loaded apps (vs reserved for the bootloader)
  • Any other requirements (e.g. a signature recognized by the bootloader)


Back in Oct someone asked about the source code to make a loadable app (see:  OpenSDA Source code), with the a release planned "in the next couple of weeks".  Short of getting the source code, is this information documented anywhere?
