Hi, Andrew Lunn

I have do that following your advice.
but it seems the driver is nerver be loaded to run.

i do these in my ethernet driver:

	NETDEVTAB_ENTRY (if_dtest_netdev,
		 "if_dtest",
 		if_dtest_init,
 		&if_dtest_sc);

	extern cyg_netdevtab_entry_t *if_dtest_netdev_ex = &if_dtest_netdev;

and linked as:

	i386-elf-gcc -nostartfiles -L..../ecos_install/lib -Llibdtest.a -Ttarget.ld -g -
nostdlib -Wl,--gc-sections -Wl,-static -o app app.o

should a modify something in the file target.ld?

what's the trouble?


Sincerely yours,
Tian-Jun

No, that it not what i said. If you don't use if_dtest_netdev_ex in
your program the linker will throw it away. If it throws it away it
will also throw away if_dtest_netdev.

Try

extern cyg_netdevtab_entry_t if_dtest_netdev;

if_dtest_netdev = if_dtest_netdev;
