Re: [ECOS] gui doesn't create bss section (was: MBX860(40MHz) stubs with cvs snapshot - mapping problem?)

["Michael Barker" <Michael dot D dot Barker at Motorola dot com>]

I tried building with the command-line config tool and target.ld gets
another line, which makes the stub build successfully; here it is -
    .sbss   ALIGN (0x4)  :      { __sbss_start = ABSOLUTE (.);
__SBSS_START__ = ABSOLUTE(.); *(.sbss) __SBSS_END__ = ABSOLUTE(.);
__SBSS2_START__ = ABSOLUTE(.); *(.sbss2) __SBSS2_END__ = ABSOLUTE(.);
*(.scommon) __sbss_end = ABSOLUTE (.); } >  ram

Also an unresolvable error which is there in the gui for this configuration
(see below) is not there when using the command line.
