[ECOS] New commer's question.

[ÕÅêÍ]

hi, here

    I wish to build eCos for a PC-motherboard target, my host is Linux and I have built the host development tools for my purpose, but I read the docs about eCos and have not found some build instructions for it, what can I do? use the "ecosconfig" tool? how to. I am a new commer here, so pls help me, thanks in advance.

Definitely read the eCos Getting Started manual.

Assuming you're using sh or bash shell, a *very* potted summary is:

ECOS_REPOSITORY=/path/to/your/eCos/repository
export ECOS_REPOSITORY
mkdir /tmp/linux-ecos-stubs
cd /tmp/linux-ecos-stubs
ecosconfig new pc stubs
ecosconfig tree
make
(put a formatted floppy in the drive)
dd if=install/bin/gdb_module.bin of=/dev/fd0

Now follow the instructions in the getting started manual for x86 (
http://sources.redhat.com/ecos/docs-latest/ ) to put this on a floppy.

You should be able to boot off this floppy image on your target PC, and if
you connect to the serial port, it should print something like
+$T05:12345[etc.]

Now to build eCos itself:

mkdir /tmp/linux-ecos
cd /tmp/linux-ecos
ecosconfig new pc
ecosconfig tree
make tests

Which will build eCos and some tests. You can then try downloading these
tests to the PC over serial using i386-elf-gdb:

i386-elf-gdb -b 38400 -nw install/tests/kernel/<VERSION>/tests/tm_basic

target remote /dev/ttyS0 (or ttyS1)
load
continue

Hopefully this will all make sense in conjunction with you reading the
Getting Started manual.
