Hi all: I Have used Configuration Tool to make a boot floppy (hardware --> i386 pc target ; package --> stubs) and a eCos kernel without conflicts (hardware --> i386 pc target ; package --> default). I insert the boot floppy into my target Intel PII pc board and use a cable to connect my host(COM1) and target(COM1). After booting my target, the target monitor shows ++$T0508:e03b0000;04:e00f0000;#44 And then I use Configuration Tool Tools-->Run Tests-->Run to test it and the following output message shows *** 10:54:31 Run started GNU gdb 5.0 Copyright 2000 Free Software Foundation, Inc.
