Original question:
Hi All,
SDK version: PROCESSOR-SDK-LINUX-AM57X 06_03_00_106
Fixed link is working but otherwise its not working.
PHY_RSTs are at gpio7_5 and 7_6, jack leds both are off orange and yellow.
Can someone guide on dtsi changes and phy resets part in dtsi?
Part number:KSZ9031RN
| Gigabit Ethernet PHY0 Address | PHYAD[2:0]=0x00 | |
| Gigabit Ethernet PHY1 Address | PHYAD[2:0]=0x01 |
we have enabled phy reset gpios for both the phys.

Hi,
There may be a few issues to work through, the first thing to understand is why the PHYs are responding to the bus probe. I would like to ask a few questions first:
&cpsw_emac0 {
status = "okay";
reset-gpios = <&gpio7 5 GPIO_ACTIVE_LOW>; ----- Why are these 2 line in cpsw node? They are usually in the mdio node.
reset-delay-us = <2>; -----
phy_id = <&davinci_mdio>, <0>; ------ Try changing this line to : phy_id = <&phy0>;
phy-mode = "rgmii";
dual_emac_res_vlan = <1>;
pinctrl-names = "default"; ----- Why are these 2 pin control lines inside the cpsw node?
pinctrl-0 = <&phy0_rst_gpios>; ------
/*fixed-link {
speed = <100>;
full-duplex;
};*/
};
Best Regards,
Schuyler
Hi Schuyler,
we have phy reset gpios(gpio7_5 & gpio7_6).Was trying to figure out how and where do we incorporate these in dts?
So the 2 pin control lines and reset gpios in cpsw nodes.Do you have any idea how do we do that?
Current dtsi looks like this now.
&mac {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&cpsw_pins_default>;
pinctrl-1 = <&cpsw_pins_sleep>;
dual_emac = <1>;
status = "okay";
};
&cpsw_emac0 {
//phy_id = <&davinci_mdio>, <0>;
phy_id =<&phy0>;
phy-mode = "rgmii";
dual_emac_res_vlan = <1>;
status = "okay";
};
&cpsw_emac1 {
//phy_id = <&davinci_mdio>, <1>;
phy_id =<&phy1>;
phy-mode = "rgmii";
dual_emac_res_vlan = <2>;
status = "okay";
};
&davinci_mdio {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&mdio_pins_default>;
pinctrl-1 = <&mdio_pins_sleep>;
status = "okay";
phy0: ethernet-phy@0 {
reg = <0>;
};
phy1: ethernet-phy@1 {
reg = <1>;
};
};
log after the phy id change

Hi,
Could you please attach snippets of where GPIOs for the PHY resets are defined in the DTS? There should be nodes defining pin mux, the mdio node, the gpio node for bank 7 being enabled?
Best Regards,
Schuyler

Hi
For DT you need to follow
elixir.bootlin.com/.../phy.txt
elixir.bootlin.com/.../ethernet.txt
So your DT should look like:
&mac {
status = "okay";
dual_emac;
};
&cpsw_emac0 {
phy-handle = <&phy0>;
phy-mode = "rgmii";
dual_emac_res_vlan = <1>;
};
&cpsw_emac1 {
phy-handle = <&phy1>;
phy-mode = "rgmii";
dual_emac_res_vlan = <2>;
};
&davinci_mdio {
status = "okay";
/* This option for the case when both PHYs has shared GPIO reset line
reset-gpios = <&gpio7 5 GPIO_ACTIVE_LOW>;
reset-delay-us = <2>;
*/
phy0: ethernet-phy@0 {
reg = <0>;
reset-gpios = <&gpio7 5 GPIO_ACTIVE_LOW>;
};
phy1: ethernet-phy@1 {
reg = <1>;
reset-gpios = <&gpio7 6 GPIO_ACTIVE_LOW>;
};
};
HI Grygorii /Schuyler,
Tried the above dts change where i moved the reset gpios inside phy node where crash is resolved but error is still the same as follows:

tried below dtsi change as well where 2 reset gpios (7_5,7_6 for phys and ETH0_INT (gpio 1_25 & ETH1_INT gpio 6_29) and also from phy datasheet
http://ww1.microchip.com/downloads/en/DeviceDoc/00002117F.pdf
Found the values for phy(compatible,asser,deassert time etc)
Could you let me know if i made any mistakes here?

1) for am57/dra7 platforms there is strict restriction - all pinmuxing has to be done only in u-boot in mux_data.h. So, pls remove all net muxes
2) Lets not add complexity for now - no interrupts, pls
3) for PHY nodes
phy1: ethernet-phy@1 {
compatible = "ethernet-phy-ieee802.3-c22"; <-- not needed
interrupt-parent = <&gpio6>; <-- remove
interrupts = <29 IRQ_TYPE_EDGE_FALLING>; <-- remove
reg = <1>;
reset-gpios = <&gpio7 6 GPIO_ACTIVE_LOW>;
reset-delay-us = <2>; <-- remove
reset-assert-us = <10000>;
reset-deassert-us = <100>;
};
};
Hi Grygorii,
Uboot pinmuxes are updated using pinmux tool.So i can remove the muxes in kernel.
Current dtsi with your changes looks like this

status = "okay";
//phy-handle = <&phy0>;
phy_id = <&davinci_mdio>, <0>;

};
&cpsw_emac1 {
status = "okay";
//phy-handle = <&phy1>;
phy_id = <&davinci_mdio>, <1>;
phy-mode = "rgmii";
dual_emac_res_vlan = <2>;
};
&davinci_mdio {
status = "okay";
phy0: ethernet-phy@0 {
reg = <0>;
reset-gpios = <&gpio7 5 GPIO_ACTIVE_LOW>;

You must switch to "phy-handle" otherwise I can't help you.
Hence, following your early posts, you do have networking working in u-boot which means smth. has changed between u-boot and kernel.
1) check MDIO and GPIO pinmuxes (use "md" in uboot and "devmem" in kernel). Note. You are using non default vin2a_d10/d11 pins.
2) run "cat /sys/kernel/debug/gpio" to determine PHY reset GPIO
3) remove "reset-gpios" from PHY nodes and follow https://e2e.ti.com/support/processors/f/791/p/937659/3497599#3497599 to check if PHY reset GPIOs configured properly
4) add back "fixed-link" nodes and remove all PHYs from davinci_mdio node and all "phy-handle" properties. You should be able to boot and networking should work (as per your comments). After boot you can try to use "phytool" to probe MDIO bus like "phytoll eth0/0/0".
hi grygorii,
1. we verified all the mdio related pinmuxes in both kernel and uboot and its same but only difference is in useraccess(0x48485080) register where after we set go bit in kernel its reading 0x0000ffff and alive register in kernel reads 0 whereas it read 0x3 in uboot. For testing purpose we even disabled all the peripherals including mdio mac but something is affecting the useraccess register.

2. o/p of this "cat /sys/kernel/debug/gpio" - Phy reset are not happening even with reset gpios set under phy nodes. Its not resetting both leds in jack are off.
3. Yes have tried that as well. I can manually do phy reset on the gpios but once leds are on, if i do ifconfig eth0 up and down it gives out same phy not found error.

4.with fixed link below dtsi changes it works. dhcp and static ip both works as well.
&mac {
status = "okay";
dual_emac;
};
&cpsw_emac0 {
status = "okay";
//reset-gpios = <&gpio7 5 GPIO_ACTIVE_LOW>;
//reset-delay-us = <2>;
//phy-handle = <&phy0>;
//phy_id = <&davinci_mdio>, <0>;
phy-mode = "rgmii";
dual_emac_res_vlan = <1>;
fixed-link {
speed = <100>;
full-duplex;
};
};
&cpsw_emac1 {
status = "okay";
reset-gpios = <&gpio7 6 GPIO_ACTIVE_LOW>;
reset-delay-us = <2>;
//phy-handle = <&phy1>;
//phy_id = <&davinci_mdio>, <1>;
phy-mode = "rgmii";
dual_emac_res_vlan = <2>;
fixed-link {
speed = <100>;
full-duplex;
};
};
&davinci_mdio {
status = "okay";
};
tested for cpsw_emac1 where reset happened during boot and for cpsw_emac0 did manual reset with gpio and that worked as well.

Hi

Pls, check bits 16-19.
Pls, use DT as i provided in https://e2e.ti.com/support/processors/f/791/p/944601/3495654#3495654
Pls, provide output for "cat /sys/kernel/debug/gpio"
Few options to try:
1) reduce MDIO freq- add "bus_freq = <20000>;" to "davinci_mdio" node
2) remove "reset-gpio" and use gpio-hog instead. add to the board file:
&gpio7 {
p5 {
gpio-hog;
gpios = <5 GPIO_ACTIVE_LOW>;
line-name = "PHY1 reset";
output-low;
};
p6 {
gpio-hog;
gpios = <6 GPIO_ACTIVE_LOW>;
line-name = "PHY2 reset";
output-low;
};
};
Hi grygorii,
0x4A00363C - mdio_d is used for uart3_ctsn so its will be muxed to 0x00090001
0x4A003640 - mdio_clk is used for uart3_rtsc so it will be muxed to 0x000D0001
Used the dts as suggested

2. removed reset and added gpio hog
this worked. able to probe micrel and ping is working.
Thank you for the help.
