Hi,

We are working on developing driver for wlan.
We use arm arm excalibur board and use lwip_stack.

I have doubt in NETDEVTAB_ENTRY() MACRO.

I will list my doubts.

1. I have given the NETDEVTAB_ENTRY() MACRO in a .inl file (first I am not
clear with .inl file...why it cant be .h file?????Plz explain).

2. Now In my high level driver code I have #included the .inl file (Where i
have my NETDEVTAB_ENTRY() MACRO) and in my high level driver code i have
given the MACRO: CYG_HAL_TABLE_BEGIN( ) & CYG_HAL_TABLE_END( )

3. In my cdl I have compiled the high level driver code with
-library=libextras.a (option).

4. Now when I check for the __NETDEVTAB__[0] and  __NETDEVTAB_END__ in a for
loop and both of them give the same address??? So its  not entering the for
loop even once.

5. if I try to print the name of the device it gives tty/diag???

I will give the sketch of the code below.My file name epx_high_driver.c

//------------------------epx_high_driver.c----------------------------------
-----------------------------------------------------------------

CYG_HAL_TABLE_BEGIN( __NETDEVTAB__, CYGDAT_DEVS_ETH_ALTERA_EPXA10_NAME );
CYG_HAL_TABLE_END( __NETDEVTAB_END__, CYGDAT_DEVS_ETH_ALTERA_EPXA10_NAME);

void init_hw_drivers( void )
{

	cyg_netdevtab_entry_t *t = &__NETDEVTAB__[0];
	cyg_netdevtab_entry_t *t1 = &__NETDEVTAB_END__;

	diag_printf("__NETDEVTAB__[0]:%02x::__NETDEVTAB_END__:%02x\n",t,t1);  //
 both t & t1 prints same address
	diag_printf("device names:%s:\n\n",t->name);  //name of the device tty/diag

	for (t = &__NETDEVTAB__[0]; t != &__NETDEVTAB_END__; t++) {
        if (t->init(t)) {
            t->status = CYG_NETDEVTAB_STATUS_AVAIL;
	}
	else {
		t->status = 0;
	}
}
}


what is the problem in the above code???? Whether I have to make any other
changes???Plz explain....................

Thanks

Regards
Vasanth
