[ECOS] configtool issue

[ECOS] configtool issue

[Chris Hiszpanski]

Hello,

I am new to eCos. I have installed the eCos tools on Windows XP under 
Cygwin, following the install instructions presented in the documentation 
(II. Installing eCos) exactly. Moving on the part III. Programming with 
eCos, I run into problems, in particular when running configtool.

When I start configtool I see a flurry of messages. Here is a snippet of 
what I see:
...
ecos.db, package CYGPKG_DEVS_FLASH_POWERPC_TS1000: warning
    This package does not have any valid version subdirectories.
ecos.db, package CYGPKG_DEVS_ETH_POWERPC_TS1000 warning
    Version subdirectory `ts1000' does not have a CDL script 
`ts1000_eth_drivers.cdl'
...
<repeated hundreds of times for various packages>
...
Is this normal?
Where do I go from here?
The documentation does not seem that it is meant to be followed 
sequentially. It seems that I should next follow section VI. Configuration 
and the Package Repository to create an eCos build tree for my project. Is 
this true?
Following section VI, I tried ecosconfig new arm7tdmi. As expected arm7tdmi 
is not a valid target. Where are the valid targets lists?

My current goal is to get eCos and its TCP/IP stack running to a pingable 
state on my own hardware (see 
http://www.its.caltech.edu/~hiszpans/ethphone/ethphone.html for minimal 
documentation). I'm somewhat lost as how to do this. Do I need to create a 
custom ecos.ecc file for my hardware? Some pointers would be helpful and 
appreciated.

Cheers,
Chris

Sort of. Its a bug which appears with recent cygwin packages. See

http://bugs.ecos.sourceware.org/show_bug.cgi?id=1000095

You can get an updated version of configtool from 

http://www.ecoscentric.com/devzone/configtool.shtml

ecos.db in the packages target. arm7tdmi is a processor not a
target. eCos targets are real boards, not processors, since a target
is much more than just the processor.

You need to compare your hardware with the other ARM targets and
decide which is the closet. You then need to use that as a starting
point for your port. There is information about porting eCos in

http://ecos.sourceware.org/docs-latest/ref/hal-porting-guide.html

And the book "Embedded Software Development with eCos"

[ECOS] MIPS issue

[neuwald]

Hello,


Hi all,

I would like to build an application to perform on MIPS simulator. I read the
"Embedded Software Development with eCos" and online documentation. Isn't
possible for me to use redboot because I don't have floppy disk, how is showed
in the examples of book.
Is it possible to build and run a simple "Hello wolrd" to run on MIPS 
simulator
without to use redboot?

Regards,
Evandro

Probably, if you ask on the gdb mailling list.

Please do not post the same message twice. There are many reasons why
you might not get a quick response to a question. Maybe nobody knows
the answer, or the people who do know the answer are currently busy
doing other things. People do not get paid for answering questions on
ecos-discuss, it is a volunteer thing. If you are worried about the
unlikely event of the mailing list software dropping a posting, you
can check the archives at http://ecos.sourceware.org/ml/ecos-discuss/

When it comes to toolchain issues like this ecos-discuss is not
normally the appropriate forum. Instead you should ask on a gdb
mailing list, see http://sourceware.org/gdb/

The MIPS TX39 toolchain support is fairly old. I am not sure it gets
much use or testing these days, so the code may have suffered from
bitrot. One possibility is to try an older version, say 5.1, although
then there is a risk that the code no longer builds because of
host-side changes - especially under Windows. 

These days are alternatives to simulators, e.g. the synthetic target
for Linux users (make sure to use anoncvs eCos rather than 2.0), or
the PC target using some old PC hardware that is lying around.
