[U-Boot-Users] at91 and lxt971 phy

[zoldnap at freemail.hu]

Hi!

Is there someone using the combo in $SUBJECT?

I'm using a modified at91rm9200dk.h config file, the ethernet relevant
section:

#define CONFIG_DRIVER_ETHER
#define CONFIG_NET_RETRY_COUNT          20

/*
 * MII PHY configuration
 *
 */
#define CONFIG_MII              1       /* MII PHY management
*/
#define CONFIG_PHY_ADDR         0       /* PHY address
*/
#define CONFIG_PHY_CMD_DELAY    40      /* PHY COMMAND delay
*/
                                        /* 32usec min. for LXT971A
*/
#define CONFIG_PHY_RESET_DELAY  300     /* PHY RESET recovery delay
*/

#define CONFIG_ETHADDR 02:80:ad:20:31:c8

#define CONFIG_IPADDR 192.168.0.100
#define CONFIG_SERVERIP 192.168.0.2

(for the full setup, see the bottom of the mail)

after starting u-boot i do:

U-Boot> tftp 21000000 zImage
PHY not connected!!
TFTP from server 192.168.0.2; our IP address is 192.168.0.100
Filename 'zImage'.
Load address: 0x21000000
Loading: T T T T T T T T T T T T T T T T T T T T
Abort

On the server PC i'm using tftp-hpa server. Here is the dump of the
ethernet traffic:

It looks like that u-boot is ignoring the returned packages for some
reason.
Maybe u-boot is still configured to think that the phy is a dm9161,
as on the original AT91 DK board?
How to change that to the LXT971?
What could be that cause that outgoing packages are OK, but incoming
packages are ignored?

I'd appreciate any hints on this!

Zoli
