Tcp_ip, Sopc

Hi Jakob,

I checked the the driver files(smsc91x.c, smsc_mem.c, smsc_phy.c), and they are not calling any UCOS-II functions. I copied the 'altera_avalon_lan91c111' directory from the superloop zip file(downloaded from nios wiki) to 72\quartus\sopc_builder\components\. And i think this it will create the HAL folder with lan91c111 driver files.

I debugged to find why it is unable to locate any working interfaces, and I came to know that the error is occuring due to the function iniche_devices_init( ). As part of netmain_init, the iniche_devices_init( ) function will be called and in this function, it seems the 'alt_iniche_dev_list' is not having any 'alt_iniche_dev' nodes, that is why it is returning the 'if_count'(interfaces found) as 0. In the following function, when i printed p_dev, p_dev_list_end, both are printed as same values. So it is not entering into the while loop and if_count=0.

int iniche_devices_init( int if_count)

{

alt_iniche_dev *p_dev;

alt_iniche_dev *p_dev_list_end;

/* Get the InterNiche device list. */

p_dev = (alt_iniche_dev *) (alt_iniche_dev_list.next);

p_dev_list_end = (alt_iniche_dev *) (&(alt_iniche_dev_list.next));

printf("p_dev=0x%x\n",p_dev);

printf("p_dev_list_end=0x%x\n",p_dev_list_end);

/* Initialize each InterNiche device. */

while (p_dev != p_dev_list_end)

{

/* Initialize the InterNiche device data record. */

........

........

/* Perform device specific initialization. */

(*(p_dev->init_func))(p_dev);

/* Get the interface IP address. */

..............

..............

/* Initialize next device. */

if_count++;

p_dev = (alt_iniche_dev *) p_dev->llist.next;

}

return (if_count);

}

The 'alt_iniche_dev' node should be inserted into the 'alt_iniche_dev_list' as part of the alt_sys_init( ), which will be called before the application main( ) function. The alt_sys_init( ) calls the ALTERA_AVALON_LAN91C111_INIT( LAN91C111, lan91c111 ); macro to register the lan91c111 driver(by adding to the 'alt_iniche_dev_list').

So it seems the registering of lan91c111 is not happening properly.

Thanks,
