I am working on FRDM-K64F board. I build the project and after debugging I get the following:
No source available for "(gdb.proc.threadGroup[i1],gdb.proc.OSthread).thread.frame"
No source available for "0x3848"
No source available for "0x2592"
The address keeps changing. I also get the following warning on the console:
Warning: the current language does not match this frame.
Temporary breakpoint 2, main () at ../Sources/main.c:65
Regarding your issue, we need to know the tools and version you are using, for example KDS/IAR/Keil...,if it is convenient, you'd better attach all your project so that we can have a debug.
