Dear, Jonathan,

I used option -msdata=none to compile both eCos library and example/twothread.c.

But, I got below Map file which says simple_threadA/B are
allocated to .sbss section.

 *(.sbss)
 .sbss          0x01045a44        0x8 twothreads.o
                0x01045a44                simple_threadB
                0x01045a48                simple_threadA
 .sbss          0x01045a4c        0x4
//e/eCosSeIma/install/lib/libtarget.a(libc_mainthread.o)
                0x01045a4c                __sncyg_libc_main_thread
                0x01045a50                __SBSS_END__=M(.)
                0x01045a50                __SBSS2_START__=M(.)

Did I miss anything?

Thanks for your  reply,

Daeyoung
