I'm trying to make ethernet working with a LAN8742A PHY, connected to eqos, in RMII mode.
I've taken the imx93-11x11-frdm.dts as base reference, and made the following changes :
&iomuxc {
pinctrl_eqos: eqosgrp {
fsl,pins = <

};Result in uboot is :

Result in linux is :
[ 11.484536] imx-dwmac 428a0000.ethernet: Failed to reset the dma
[ 11.490536] imx-dwmac 428a0000.ethernet eth0: stmmac_hw_setup: DMA engine initialization failed
[ 11.499228] imx-dwmac 428a0000.ethernet eth0: __stmmac_open: Hw setup failedI don't understand what i am doing wrong, what i misconifgured, or why the dma does not initialize properly. It's pretty obvious that i'm missing something (a dma error looks like an internal error from the chip, so even if there was an error with the pinmux i don't thihnk i would get this, and i double checked the pinmux).
Things i have checked :
- clock is correctly sent to the PHY
- communication with the PHY on mdio works
Any hints on this would be greatly appreciated,
Best regards,
Julien
Reset is set correctly in uboot. I can see the PHY live (the leds work), and communicate with it, but i still get the DMA error.
I tried manually disabling and reenabling the PHY via the reset pin in u-boot, but this didn't change anything.
Here is the complete log from dmesg :

Hello,
Please confirm that reset is asserted correctly in the PHY.
When the PHY is not provided with the clock for a brief period and the clock is enabled back, a reset must be provided to the PHY to latch all the configuration straps, recover into the normal working mode.
Please share your entire dmesg.
Best regards.
Hello,
Thank you for the information.
Since registers can be accessed, the MAC is not completely held in reset.
Could you please share the schematic connections to confirm how REF_CLK is provided?
Also, please share your clock summary in cat /sys/kernel/debug/clk/clk_summary
Best regards.
I don't want to share the full schematics on a public forum. Can i send them privately ?
REF_CLK is provided via ENET1_TD2 (pin U12 of imx93). In device tree, this is this line :
MX93_PAD_ENET1_TD2__CCM_ENET_QOS_CLOCK_GENERATE_REF_CLK 0x57eWe have checked with an oscilloscope that the clock is correct under u-boot, but we encounter a similar dma error (with less details).
Under linux, something is stopping the clock (my guess is that the dma error triggers a release of the clock, which is then stopped by linux kernel as unused).
Here's the content of clk_summary :
enable prepare protect duty hardware connection
clock count count count rate accuracy phase cycle enable consumer id

# Please see the other message for my answer about the ref_clk and the schematics, it looks like i mistakenly used the wrong reply button.
I also tried the following : https://community.nxp.com/t5/i-MX-Processors/i-MX93-EQoS-RMII-mode-with-internal-50MHz-reference-clo... which looks a lot like the same issue, but could not get it to work as well.
Thanks for your support,
I could finally get it to work, using the patch in the link, and the following settings :
&eqos {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_eqos>;
phy-mode = "rmii";
phy-handle = <ðphy1>;
status = "okay";
assigned-clock-parents = <&clk IMX93_CLK_SYS_PLL_PFD1_DIV2>,
<&clk IMX93_CLK_SYS_PLL_PFD0_DIV2>;
assigned-clock-rates = <100000000>, <50000000>;
enet_clk_sel = <&wakeupmix_gpr 0x2C>;
clk_csr = <5>;
// snps,rmii_refclk_ext;
mdio {
compatible = "snps,dwmac-mdio";
#address-cells = <1>;
#size-cells = <0>;
clock-frequency = <5000000>;
ethphy1: ethernet-phy@0 {
reg = <0>;
eee-broken-1000tx;
reset-gpios = <&pcal6524 19 GPIO_ACTIVE_LOW>;
reset-assert-us = <15000>;
reset-deassert-us = <100000>;
smsc,disable-energy-detect;
};
};
};Could you explain me what the patch in https://community.nxp.com/t5/i-MX-Processors/i-MX93-EQoS-RMII-mode-with-internal-50MHz-reference-clo... does, why it is needed?
Also, shouldn't these changes be upstreamed, as they look like a regular use case for the soc, nothing exceptional?
Hello,
Is good to know that is now working.
The patch modifies the driver dwmac-imx/EQoS to configure ENET_QOS when RMII is using an external clock.
This change is needed because EQoS needs a constant clock during DMA reset.
Best regards.
