Exactly how did you configure eCos (please explain all the steps)?

For example, I can build RedBoot for the i386/PC using these steps:
  % ecosconfig new pc redboot
  % ecosconfig import ${ECOS_REPOSITORY}/hal/i386/pc/current/misc/redboot_GRUB.ecm
  % ecosconfig tree
  % make

Why do you want to rebuild the config tool (an arduous task, even for
the seasoned traveler!)??

You'll need to explain what error you are getting.

[ECOS] SO many ecos problems in learning ecos and they has made me crazy....SOS....

[sean yang]

I just learned to use ecos to build a i386 redboot follwing the http://ecos.
sourceware.org/，and I am confused by what I got:

1. I downloaded the ecos via wget as the instruction of
http://ecos.sourceware.org/getstart.html: wget --passive-ftp
ftp://ecos.sourceware.org/pub/ecos/ecos-install.tcl and install 

It,the ecos has been installed with the directory structure such
as:ecos/ecos-2.0/packages/hal/i386/arch/ecos-2.0;

 2. Then,I got the snapshot via
http://www.ecoscentric.com/devzone/snapshots.shtml and reinstalled it ,this
time the directory structre is ok as normal mentioned:

ecos/packages/hal/i386/arch/current;

 3. Then,I use the snapshot version to build the i386 and arm tool
chains,and then the redboot for i386 with configtool.exe(Version
0607)----BTW,and I don’t know how to get the configuretool_v1.3.net for
MLT---there is a error for building which confusing me so long a time:

make[1]: *** [src/redboot_linux_exec.o.d] Error 1

make: *** [build] Error 2

 

4. from the make log,there are two errors which I don’t know why at all
because:

   1).EAX has been declared in i386_stub.h and this file will be included by
hal_syscall.c if CYGSEM_REDBOOT_BSP_SYSCALLS defined,and I am sure that the
MACRO CYGSEM_REDBOOT_BSP_SYSCALLS has been defined;

   2).the cyg/crc/crc.h:this file will be included in redboot.h,but I
couldn’t find this file in this directory,why?could anyone tell me ?

 

5.I want to rebuild the confiuretool with the latest snapshot version,and I
followed the http://www.ecoscentric.com/devzone/configtool.shtml

  But the $HOME can not be understood by cygwin bash ,why?

Thank u very much …..
