AM3352: AM3352 Ethernet CPSW RGMII 10Base can not work

Part Number: AM3352

Tool/software:

Hi Expert,

The customer is currently using TI AM3352 with Broadcom BCM54210S PHY, and there is no problem at 1000 or 100Mbps.

But it doesn’t work at 10Mbps!

The PHY has detected that the other party is 10Base-T and Link Up. Using tcpdump, you can receive the packets sent by the other party, but the CPU cannot send out the TX packets!

Check the _cpsw_adjust_link function in cpsw.c. I'm sure we have set the in-band mode (MACCONTROL BIT 18). Is there anything else we need to pay attention to?

The customer has confirmed that the in-band mode (MACCONTROL BIT 18) has been set. Is there anything else that needs attention?

SDK 06_03_00_106, Linux kernel is 4.19.94

_cpsw_adjust_link :

if (phy->link) {
mac_control = cpsw->data.mac_control;

/* enable forwarding */
cpsw_ale_control_set(cpsw->ale, slave_port,
ALE_PORT_STATE,
priv->port_state[slave_port]);

if (phy->speed == 1000)
mac_control |= BIT(7); /* GIGABITEN */
if (phy->duplex)
mac_control |= BIT(0); /* FULLDUPLEXEN */

/* set speed_in input in case RMII mode is used in 100Mbps */
if (phy->speed == 100)
mac_control |= BIT(15);
/* in band mode only works in 10Mbps RGMII mode */
else if ((phy->speed == 10) && phy_interface_is_rgmii(phy))
mac_control |= BIT(18); /* In Band mode */

if (priv->rx_pause)
mac_control |= BIT(3);

if (priv->tx_pause)
mac_control |= BIT(4);

*link = true;

if (priv->shp_cfg_speed &&
priv->shp_cfg_speed != slave->phy->speed &&
!cpsw_shp_is_off(priv))
dev_warn(priv->dev,
"Speed was changed, CBS shaper speeds are changed!");

Hi,

There are no changes required to support 10Mbps this should happen automatically as CPSW is setting based on information read from the PHY.

Please post the results of ethool eth0.

How are you setting up for 10Mbps?

Thank you for posting the SDK and Kernel version, please this SDK is over 4 old and 2 years past the support window. The support TI provides maybe limited.

Best Regards,

Schuyler

Hi,

When I see messages like below usually means auto-neg is not completing as expected. 10Mbps half duplex is typically the last attempt of the PHY to establish a link.

cpsw 4a100000.ethernet eth0: Link is Up - 10Mbps/Half - flow control off

Do you have a TI-EVM by chance to test the setup with?

The statement about not being able to advertise speed 10 after the ethtool setup is concerning. This may imply the hardware configure of the PHY is not setup. Please attach the results of ethtool eth0, I am looking to see what is being read from the PHY indicating what speeds are being advertised.

Best Regards,

Schuyler

Hi Schuyler

The ethtool command to set speed must be followed by duplex full or duplex half parameter, or ethtool command will just report error.

I follow duplex full, and the command works, but the traffic is still not be able to send in 10Mbps full.

After issued the command, ethtool eth0 shows the advertisement is only 10baseT/Full

Typically, the ethtool eth0 will advertise all the possible combinations, shown as below:

And the PHY is able to detect the link speed and report to the driver.

The issue is that why the CPU's RGMII_TXCTL is not asserted while sending out the packet.

Other pins including clock and tx pins are all working fine per our measurements.

Thanks

Daniel

Hi,

Apologies, I should have asked this in the previous post. Do you have access to ethtool on the link partner? Do you have a TI EVM that you could use as a link partner?

Best Regards,

Schuyler
