RE: [ECOS] confused about running program on remote target

["Erik Reikes" <ereikes at hotmail dot com>]

Huzzah!

Success!

Here's what I did to make it work :
I'm using win2k professional FYI.
The first thing I did was delete everything... ecos, cygwin, all the files 
and directories in cygwin, every tar.gz and tar.bz2 I downloaded for the 
whole project.

I then redownloaded everything in the exact versions as specified on the 
redhat ecos directions :

binutils 2.10.1
gcc 2.95.2 core and g++ (straight from sources.redhat/ecos)
insight 5.0
The insight patch.
The gcc patch.
The new config tool 1.3.net from ecos.


I installed _every_ package in cygwin, no matter how seemingly unrelated.

Then I followed the exact directions on the ecos "how to build the tools 
page".  Right down to the exact directories specified for builds and 
everything.  I directly cut and pasted from their web page, in the exact 
same order.

Then I installed the 1.3.1 exe distribution.
Then I unzipped the 1.3.net configtool right into the 
Programfiles|RedHAt|ecos|tools|bin directory.
Then I ran their registry update fragment.
Then I cvs'd a fresh brand new copy of the ecos distribution in a directory 
/Master_Ecos.
I cp -r *'d everything in there to a directory in cygnus called /devel_ecos.

Then I started configtool 1.3.net and before doing anything I pointed the 
repository to c:/cygwin/devel_ecos.

Then I made a directory c:/TEMP/ecos_build.
I set build|template to i386 pc target and switched the packages to minimal 
and saaved the ecc as c:/TEMP/ecos_build/i386min.ecc.  Then set the build 
(c:/cygwin/tools/H-i386-pc-cygwin/bin) and tools (c:/cygwin/bin) paths and 
said build|library.  This build of minimal tools succeeded and was more of a 
test than anything.

then I said file|new, set build|template to i386 pc target and set the 
packages to redboot.  After this I said file|import 
c:/cygwin/devel_ecos/packages/hal/i386/pc/current/misc/redboot_FLOPPY.ecm.

Then I said file|save c:/TEMP/ecos_build/i386redboot.ecc and said 
build|library.  Lo and behold there was a redboot.bin in the 
i386redboot_install/bin directory.  I dd'd the file to the floppy as 
explained in the redboot documentation and it booted up giving me redboot.

I tried to run the tests from a template = i386|default build, but they are 
still referencing the c drive as //c/, and I haven't gotten around to 
figuring out some sort of path mangling to get around this, but I went into 
cygwin and went to my repository directory /devel_ecos/examples.  Changed 
the settings in the makefile for Repository_install (where your libtarget.a 
lives... for me it was something like /cygdrive/c/TEMP/i386default_install 
and build option (uncommented the i386 pc one) and said make at the command 
line.  The examples made and I said gdb helloworld.exe. up pops insight, I 
set the options for target to COM1 38400 and said run.  It downloaded and a 
screen flickered by real quick but when I managed to get it stopped it said 
: "Hello ecos-world...about !@#$ time!".

Ok, I forgot the part where I edited the hello-world source with my own 
little message and !@#$ was something else probably not appropriate for this 
forum.  ;)

Now if you've gotten this far this is the most important step : I shut down 
my computer, found a short round glass (some call it a tumbler) placed two 
ice cubes in it followed by about three fingers of Jack Daniels, downed it 
and went to sleep.

I'm not at all sure what the actual problem (or problems) I was having, but 
I originally tried to use gcc-3.0.3 with the newest binutils and insight 
5.1, I later tried to switch to 2.95.2, but it didn't seem to help.  Some 
combination of corruptions of tools and/or repository and/or configtool was 
probably the culprit.

Sorry for the rambling, no complete sentences, poorly punctuated message.

Hope that helps!
