Hello,
I'm sorry,since I am a Japanese it took me long time to write reply.

I apologize for lengthy reply.
I already made "MyTarget" template for my board, copying and amending
"Hitachi SE77x9 board" template.
I already checked RedBoot is working properly.
I am chechikng SMSC LAN91C111 driver(if_lan91cxx.c) using eCos test program
"nc_test_slave.c".
I build using "MyTarget" hardware template and "net" package template,and
link to nc_test_slave.c.
My target's configuration is like next.

I think if I could call lan91cxx_start routine properly,lan91cxx drv will
work,
but as I said in previous mail,since ng_ether_attach_p == NULL,I couldn't
execute
attach routine (*ng_ether_attach_p)(ifp);
As a try,I inserted next coding before calling (*ng_ether_attach_p) in
ether_ifattach().
ng_ether_attach_p = if_attach;
if (ng_ether_attach_p != NULL)
(*ng_ether_attach_p)(ifp);
Then executed (*ng_ether_attach_p)(ifp) and jumped
if_attach(ifp)
in packages\net\bsd_tcpip\current\src\sys\net\if.c
But lan91cxx_start was never called.
Although I cannot understand how lan91cxx_start is called,
looks like the mechanism that calls lan91cxx_start is not working.

What do I lack to install lan91cxx driver ?
I would appreciate any help.
