Hi,
Thanx for immediate reply.
Eric as per your info , i have successfully build (libtarget.a) the platform using net package/RAM startup.
But when i try to link the basic.c example application given in chapter12 of 'Embedded software Development with eCos' doc to libtarget.a , i have got the error as given below.The make file for above i have send as attachment (Application named as rb8139).

Please mail me where i am going wrong.
I have also tried out configuration 'i386 pc with 8139' with 'redboot',still redboot Networking options remains disabled.Than how i should ableto enabled the network debugging ?
Kindly also maill me the detail, how i can boot my system using 'libtarget.a' generated by your suggested configuration.

Regards,
Dhawal.

You will also need a 'target' in ecos.db somewhat like this:

target pc_8139 {
   alias    { "i386 PC target with RealTek 8139 ethernet" }
   packages { CYGPKG_HAL_I386
              CYGPKG_HAL_I386_GENERIC
              CYGPKG_HAL_I386_PC
              CYGPKG_HAL_I386_PCMB
              CYGPKG_IO_PCI
              CYGPKG_IO_SERIAL_GENERIC_16X5X
              CYGPKG_IO_SERIAL_I386_PC
              CYGPKG_DEVS_ETH_RLTK_8139
              CYGPKG_DEVS_ETH_I386_PC_RLTK8139
              CYGPKG_DEVICES_WALLCLOCK_DALLAS_DS12887
              CYGPKG_DEVICES_WALLCLOCK_I386_PC
            }
   description "The pc target provides the
             packages needed to run eCos binaries on a standard i386
             PC motherboard (with RealTek 8139 NIC)."
}

Then, in the configtool choose the menu item 'Build->Templates', and
select the pc_8139 target and the 'net' package in the dialog. It
shouldn't matter if the 8139 is onboard or not to the driver.
Please note that I don't have an i386 PC target to test so I can't
really help you much further if there are PC-specific problems.
