I am using the eCos synthetic Linux build for testing and initial
development. I looked at all of the current ports and do not believe
any of them fit my requirements. The main requirement is that it use a
standard bus such as PC-104 for adding commercial ADC/DAC and other I/O
modules. Cost is a factor.
I am leaning toward using one of the commerical embedded 386/486/586
embedded PC SBC's with ROM/FLASH/RAM options. I am also open to MC68k
or PowerPC SBCs. Has anyone already done a port for an embedded PC
or another platform that would meet this requirement? I prefer using
eCos to embedding linux to reduce the operating system overhead and
also to have real-time performance.
Any constructive suggestions are welcome.

Hi, J.D.:
I posted an i386/PC HAL package;
http://sourceware.cygnus.com/ecos/contrib.html has a pointer to it. The
last time I updated it was the end of October, so don't be suprised if the
eCos source code has changed quite a bit--installation might not be as
straightforward as before. I'm actually planning on updating to the
current CVS version next week. Look out for a bug somewhere in the mutex
handling code: I'm sure it's related to the interrupt handler code. Stay
tuned for that fix. But in the meantime, that package allows you to
construct a GDB stub on a floppy disk, so you just boot from that and then
connect to the debugger from COM1. If you have any significant problems,
just e-mail questions to this list, that way everyone benefits from the
discussion. Cheers!

Patrick and ecos-discuss,
Thanks, I thought I had looked at the cygnus site more carefully,
but there it is. I am beginning to think that RTLinux may serve my
needs a bit better for the embedded PC since I am developing a
monitor/control application in Linux. So I am looking into that also.

In this case, perhaps you should look into EL/IX which is an effort by
Cygnus to bridge exactly this gap.

Patrick and ecos-discuss,
I am forging ahead with the ecos i386-pc build. I think I set
everything up the way Patrick's html files described it starting from
the ecos-1.2.1.tar distribution tree. I am building using RedHat
6.0. I first untarred only the latest file: hal-i386-pc-19991028.tgz
I got the error below. I decided to go back and untar the initial
release (hal-i386-pc-0.1.tar) followed by the second release
(hal-i386-pc-19991022.tgz) and then the final version
(hal-i386-pc-19991028.tgz) just in case it was meant to be done that
way, but I still get the same error when building the gdb stub:
[charlton@marble ecos-i386-stub]$ tclsh ~/cygnus/ecos-1.2.1/packages/pkgconf.tcl \
> --target i386 \
> --platform pc \
> --startup floppy \

> --disable-uitron \
> --disable-libc \
> --disable-libm \
> --disable-io \
> --disable-io_serial \
> --disable-wallclock \
> --disable-watchdog
pkgconf fatal error: The file /home/charlton/cygnus/ecos-1.2.1/packages/packages \
lists a package CYGPKG_HAL_ARM_CL7211 which should be present in \
/home/charlton/cygnus/ecos-1.2.1/packages/hal/arm/cl7211. This package is missing.
[charlton@marble ecos-i386-stub]$
Any help is appreciated.

It looks like Patrick's files were [somewhat] based on newer files.
Try removing these lines from "packages/packages":
package CYGPKG_HAL_ARM_CL7211 {
alias { "Cirrus Logic CL7211 evaluation board support" hal_arm_cl7211 arm_cl7211_hal }
directory hal/arm/cl7211
include_dir cyg/hal
hardware
}
Let me know if you continue to have problems.

I think I am making progress. I removed the offending packages (I had
to remove about 5 total). Now I get the following error when processing
targets:

Looking at Patrick's release notes for the hal-i386-pc-19991028.tgz
file, that release is intended to work with the current sources as
available via anonymous CVS
( http://sourceware.cygnus.com/ecos/anoncvs.html ). The base_platform
facility was added to pkgconf.tcl and the targets file after the eCos
1.2.1 release, so trying to use that release in conjunction with
hal-i386-pc-19991028.tgz is going to be problematical. In fact there
may be other incompatibilities as well.
You will need to either:
1) work with the current eCos anonymous CVS sources, in conjunction
with Patrick's latest release.
or:
2) work with the eCos 1.2.1 release and Patrick's original
i386-pc-0.1.tgz file.
I suspect the earlier problems were caused by a similar
incompatibility problem.

Hi, JD--
Sorry you're having so much trouble. I'd hoped to get some time last week
to update the HAL to the current CVS version of eCos; but, of course,
that's when my customers call and want me to spend a few days out of town.
I've tarred up my eCos source tree and posted it for you--just download
ftp://sourceware.cygnus.com/pub/ecos/contrib/hal/i386/ecos-i386.tgz , and
try the pkgconf.tcl script from there. Let me know if that helps.
