Post subject:  Ethernet problem with at91sam9260ek

Hi to all,
I make a at91sam9260-ek in my home. I could boot up the linux on it. But I have one problem.
My problem is that Ethernet.
Some lines in boot-up logo are in the following lines:

Code:
U-Boot 1.3.4 (Mar  9 2010 - 19:29:50)

DRAM:  64 MB
NAND:  256 MiB
In:    serial
Out:   serial
Err:   serial
Net:   macb0
macb0: Starting autonegotiation...
macb0: Autonegotiation timed out (status=0x7849)
macb0: link down (status: 0x7849)
....
...
...
...
MACB_mii_bus: probed
eth0: Atmel MACB at 0xfffc4000 irq 21 (3a:1f:34:08:54:54)
eth0: attached PHY driver [Davicom DM9161A] (mii_bus:phy_addr=ffffffff:00, irq=-1)
...
...
...


I don't know that I have a hardware probmel or no.
Can you help me based on the log?
I have a problem in u-boot
macb0: Starting autonegotiation...
macb0: Autonegotiation timed out (status=0x7849)
macb0: link down (status: 0x7849)


and in kernel I have these lines:
MACB_mii_bus: probed
eth0: Atmel MACB at 0xfffc4000 irq 21 (3a:1f:34:08:54:54)
eth0: attached PHY driver [Davicom DM9161A] (mii_bus:phy_addr=ffffffff:00, irq=-1)


I want to know that the DM9161 is detected or no?

I could set IP with the following line:
ifconfig eth0 192.168.1.200 up

But I haven't ping.

Help me plz.

I attached my schematic for DM9161 and AT91sam9260.
Please see it.
I soldered the S601 and unsoldered R605 (pin36 of DM9161).
My configuration is set for MII mode.
Also I change my uboot:
#undef CONFIG_RMII
#define CONFIG_RMII 1
Image

Also I modify my u-boot codes to print PHY_ID1.

I have these lines in terminal:
Code:
U-Boot 1.3.4 (Mar  9 2010 - 19:29:50)

DRAM:  64 MB
NAND:  256 MiB
In:    serial
Out:   serial
Err:   serial
Net:   macb0
phy_id= 0x181
macb0: Starting autonegotiation...
macb0: Autonegotiation timed out (status=0x7849)
macb0: link down (status: 0x7849)
....

MACB_mii_bus: probed

eth0: attached PHY driver [Davicom DM9161A] (mii_bus:phy_addr=ffffffff:00, irq=-1)
...

Do you have any Idea?
I haven't connection with LAN.
The status=0x7849 say that autonegotiation has a problem.

Please help me.
I don't know that my problem is for hardware or software?

You misunderstand basic forum dynamics, many people focused on their own problems, few with answers.

#define CONFIG_RMII 1 ??

Doesn't ETXCK need to be connected to REFCK in RMII mode? Have you tried the 50MHz mode like the original 9260-EK?

#undef CONFIG_RMII
#define CONFIG_MII 1

Confirm VCCA voltage
Confirm specific DM9161 part number, many variants

Thank you.

Oh, I'm sorry. I have a mistake.
I modified my u-boot in this state:
Code:
#undef CONFIG_RMII
#define CONFIG_MII 1
:roll:

No, I don't test with 50Mhz and RMII mode.
But in MII mode I could print the PhyID1 and PhyID2 that exactly match with the DM9161.

I replace the LAN connector and change u-boot configuration to MII mode(xtal=25Mhz used).
In this state, I could receive file with tftp command in u-boot, But I can't use the lan network after booting up the linux kernel.

Does any modification needed in kernel to changing to MII mode?

please help me.
