I am using Eclipse as debugger IDE and it have got the same problem.
We have fixed this problem .
There is a utility called "cygpath.exe" to convert Unix path to windows
path.
We have used this utility and dynamically convert Unix path to Windows.

Hi Adolfo,

Being a rather experienced developer using the eCos + Lauterbach 
combination, I haven't either found any good way of using T32-Win 
together with code compiled under Cygwin due to the problems You are 
describing :-(

Luckily, this problem can easily be solved by switching to a Linux build 
and debugging host instead - The T32 is very well working under Linux 
(provided You are using the Ethernet-based HW-interface variant), and 
the eCos build environment is generally better working in native Linux 
environment.
If You peek around a little in Your T32 installation CD (check e.g the 
t32\demo\powerpc\kernel\eCos directory), You will even find that there 
is a T32 plugin providing eCos kernel awareness and some eCos menu 
extensions avaliable for the T32 :-)

Happy T32-eCos debugging!

RE: [ECOS] ecos-c

[Daniel Lidsten]

Hi,

I have been using Lauterbach also and there is an option called
/StripPART that can be used for this when loading the image. It will
remove as many parts of the path as you want. You then setup the
symbol.List.SPATH to reflect the new path to use.

The below rows will remove /ecos-c/ and use your home directory instead.

Data.Load.Elf file.out /LowerPath /StripPART 1
Symbol.SPATH F:\Jose

Sorry about my first short answer.

My first idea was to make the cygwin path match the windows patch with
exception of the drive letter. A lot of windows apps are resistant to
both separators. I don't know if T32 is, but it might. GCC will store
the path given by ecosconfig anyway, and ecosconfig does not even let
us make a single try.

I doubt even that. GCC will store the absolute path to a file in the 
file's debug sections. GCC is a cygwin application, so it will store a 
cygwin path. I don't think there's anything you could do other than doing 
some binary patching on the file!

IMHO, cygwin is not involved. It's more likely an issue of ecosconfig options. I mean, the Makefile
variant generated is only configurable via a static #define, while it may be controlled via command
line.

[ECOS] ecos-c

[Adolfo Lucha]

Hello,

i am not sure if this the right discussion forum for my question. Sorry if it is not.

I am developing a system with eCos on a own ppc HW. I am using T32 debugger from http://www.Lauterbach.de company. It will show me my private project files in a rigth manner but the eCos files will not be showed. The problem is that the debugger will not found the files because the path is prefixed with "/ecos-c/...". T32 is a Win32 application and can not expand such text to a drive letter. Therefore I am not able to step through the eCos code.

I fell that there is a compiler or linker flag to say: do not use the cygwin path ("/ecos-c/"), and use the windows drive letter instead. Is not it? I did not find it :-(

Or need I any settings in the cygwin environment? Mount flags? ECos configuration settings?

Any Idea?

thanks and regards,
Adolfo
