Hi All,
We are working on a custom hardware platform based on s32g2. where we are trying to make GMAC0 Eth communication working.
GMAC0 is connected to external PHY "DP83848Q" as in the attached schematic section:
The DTS setting is as:
&gmac0 {
status = "okay";
clocks = <&clks S32CC_SCMI_CLK_GMAC0_AXI>,
<&clks S32CC_SCMI_CLK_GMAC0_RX_MII>,

clock-names = "stmmaceth","rx_mii","tx_mii";
phy-interface-type = "mii";
pinctrl-names = "gmac_mii","gmac_mii";
pinctrl-0 = <&gmac0miic_pins>,<&gmac0mdioc_pins>;
phy-mode = "mii";
phy-handle = <&gmac_mdio_a_phy1>;
fixed-link {

full-duplex;
};
};
&gmac0_mdio {
status = "okay";
compatible = "snps,dwmac-mdio";
#address-cells = <0x01>;

max-speed = <100>;
full-duplex;
};
gmac0mdioc_pins: gmac0mdioc_pins {
gmac0mdioc_grp0 {
pinmux =
output-enable;
slew-rate =
};
gmac0mdioc_grp1 {

gmac0miic_grp2 {

hi @Joey_z
Ok, thanks ... Looking for resolution soon.
hi,khan_misbah
Sorry for the reply late.
I have known you post a new private ticket; we will continue to support you on it.

Joey
hi,khan_misbah
Thank you for your reply.
I know that you used the customer board and the PHY not on our development board, so I cannot be easy to reset your hardware and help you to test.
I will discuss with the internal expert team to check if there are any other ways to help you.

Hi Joey_z,
>>>> Do you mean that you can use the MII mode of GMAC0 normally during using BSP38?
yes
>>> Which content of GMAC0 has been changed in BSP38 for your hardware?
That we dont know because we dont have the sources/patch with us. What we have is only DTS file and we are expecting that with DTS change things should work, we are not expecting to hack the kernel code to make MII mode of GMAC0 to work and if that is the case we need NXP to support here because we are using BSP & SoC of NXP's
hi,khan_misbah
Thank you for your reply and the information.
Do you mean that you can use the MII mode of GMAC0 normally during using BSP38?
Which content of GMAC0 has been changed in BSP38 for your hardware? You can try to find those modified contents of BSP38 and refer to it to modify the BSP43. Mainly follow the content of dts/ATF/Kernel about GMAC0.
BR
Joey
Hello Joey_z
The hardware we are using is enclosed one, its difficult to probe the signals. Moreover it is a working hardware using Linux BSP38. With the current BSP43 we are getting this issue.
Regards,
Misbah
hi,khan_misbah
Sorry for the reply late.
Thank you for your detail information, I will help you to check it.
Also, could you use an oscilloscope to test the external clock of MII? Check if it is normal.

Joey
Hi @Joey_z
The below change you suggested is for bootloader, but we need the change in linux kernel, I tried to hardcode in "stmmac/dwmac-s32cc.c" the RX & TX clock to 25Mhz but it didnt solved the issue.
Please suggest as how shall we proceed to make the below change to get the Rx clock configured for 25Mhz
cat /sys/kernel/debug/clk/clk_summary | grep gmac0
gmac0_axi 2 2 0 400000000 0 0 50000 Y 4033c000.ethernet pclk

gmac0_rx_mii 1 1 0 125000000 0 0 50000 Y 4033c000.ethernet rx_mii
hi,khan_misbah
Thank you for your reply.
Try to remove the GMAC0 MII clock in your configuration.
&gmac0 {
status = "okay";
phy-mode = "mii";
clocks = <&clks S32CC_SCMI_CLK_GMAC0_AXI>,
<&clks S32CC_SCMI_CLK_GMAC0_RX_MII>,
<&clks S32CC_SCMI_CLK_GMAC0_TX_MII>;
clock-names = "stmmaceth", "rx_mii", "tx_mii";
phy-interface-type = "mii";
pinctrl-names = "gmac_mii","gmac_mii";
pinctrl-0 = <&gmac0mii_pins>,<&gmac0mdio_pins>;
pinctrl-1 = <&gmac0mdio_pins>;
phy-handle = <&mdio_a_phy3>;
fixed-link {
speed = <100>;
full-duplex;
};
};
Also, you can try to modify the file of dtb to limit the clock to 25Mhz.
I hope your problem can be solved. I'm sorry that I have to take a vacation of over a week. If your problem still exists, you can create a new ticket and my colleagues will provide you with support, or wait for me to come back.

Hi @Joey_z,
The device tree entry in the ATS is as:
&gmac0 {
status = "okay";
phy-mode = "mii";
clocks = <&clks S32CC_SCMI_CLK_GMAC0_AXI>,
<&clks S32CC_SCMI_CLK_GMAC0_RX_MII>,

pinctrl-0 = <&gmac0mii_pins>,<&gmac0mdio_pins>;
pinctrl-1 = <&gmac0mdio_pins>;
phy-handle = <&mdio_a_phy3>;

};
};
What additional setting is needed to get the clk in u-boot for gmac0 ?
"2. About your log, I can find the clock of MII has been configured in kernel, it is a good thing, you can try to set the gmac0_rx_mii to 25MHz."
How shall i configure the gmac0_rx_mii to 25MHz ? Is it by hwconfig or dts ? Can you suggest
hi，khan_misbah
Thank you for your reply and information.
1.Dose the clock configuration from ATF as below? I think you need not to use the SCMI for setting MII clock, the clock of MII from external PHY.
clocks = <&clks S32CC_SCMI_CLK_GMAC0_AXI>,
<&clks S32CC_SCMI_CLK_GMAC0_RX_MII>,
<&clks S32CC_SCMI_CLK_GMAC0_TX_MII>;
clock-names = "stmmaceth", "rx_mii", "tx_mii";
2. About your log, I can find the clock of MII has been configured in kernel, it is a good thing, you can try to set the gmac0_rx_mii to 25MHz.

Hi @Joey_z
The clock is getting generated by PHY (TX & RX) pls check the schematic section :
Following is my DTS setting:

pinctrl-names = "gmac_mii","gmac_mii";
pinctrl-0 = <&gmac0mii_pins>,<&gmac0mdio_pins>;
pinctrl-1 = <&gmac0mdio_pins>;
phy-handle = <&mdio_a_phy3>;
fixed-link {
speed = <100>;
full-duplex;
};
};

reg = <1>;
ref-clock = <0x17d7840>;
max-speed = <100>;
full-duplex;
};
};

hi,khan_misbah
Thank you for your reply and informaion.
Refer to your log, the clock is not correctly setting thought the external PHY.
1.About the GMAC0, your pin using is correct.
2.You can try to check the clock the PHY clock, make sure the TX/RX from the PHY and useful.
Hope this can help you.

hi,khan_misbah
Thank you reply and more information.
If you set the GMAC0 as the MII mode, you should use the ext clock for GMAC0_TX_CLK.
Please check your GMAC0 clock setting, the MUX1 of CGM6 should chose the ext clk.
About the file of s32g3.dtsi, you can try to modify the cgm6 configuration.
Hope this can help you.

hi,khan_misbah
Thank you for your reply.
Refer to you Kernel log, the Gmac0 do not connect with PHY.
Could you test the GMAC0 function in uboot and provide more information to us.
1.Check the GMAC0 clock in uboot to use the command of clk dump.
=> dump clk
2.Check the PHY of connection state with GMAC0, using the command of mii infro and mdio list in uboot.
=> print hwconfig
=> mii infro
=> mdio list
3.If connect GMAC0 with PHY successfully, could you please set Ip to Gmac0 and test the ping function.

Hello,
We are using Linux BSP43 running on A53 core as OS. We are not running M7 .
hi,khan_misbah
Thank you for your reply.
Which version of BSP are you using? And do you use the multi-core or only A core？
BR
Joey
