[teddywang]

hi all

  I try to port cm_backtrace to NXP mcu with NXP SDK under KEIL IDE 5.35,FREM_K64 SDK version is 2.11.

  my question is when I build the project with cm_backtrace,the compile information is "L6218E: Undefined symbol Image$$ER_IROM1$$Base (referred from cm_backtrace.o). and L6218E: Undefined symbol Image$$ER_IROM1$$Limit (referred from cm_backtrace.o).".how can I  modify the scf file?

In my opinion, you need check original project, which .scf file it used?

Recommend  asking KEIL support for help, they know how to config linker file more clear.
