器件型号：PROCESSOR-SDK-J721E

工具/软件：

您好、专家、

平台：J721e
构建系统：Yocto
内核：6.6.
U-Boot：2024.04

我们将从 U-Boot 2023.04改为2024.04。我们拉了标签10.01.10并将我们的 DTS-changes 放在上面。在以前版本的 SDK (8.2)中、有一些补丁可让 CPSW9G 主交换机在 U-Boot 中运行、由 Suman Anna 编写。由于我们现在处于较新的标签(10.01.10)、这些补丁不再有效。

我正在尝试使 CPSW9G 以太网端口再次工作。引导过程如下所示：

所有相关代码似乎都在最新的10.01.10标签中。有人能帮助我让它再次工作吗？

此致、

更新了。

我注意到根本没有探测 am65_cpsw_Nuss 驱动程序( am65_cpsw_probe_Nuss 函数中没有 printf：s 有效)。我不得不补充：

&cpsw0 {

+    compatible = "ti,j721e-cpsw-nuss";

The updated k3-j721e-main.dtsi had:

compatible = "ti,j721e-cpswxg-nuss";

这使得驱动器不会进行探测。这现已解决、下一个问题是 phy_connect：

/drivers/net/ti/am65-cpsw-nuss.c:791-am65_cpsw_probe_nuss() am65_cpsw_nuss ethernet@c000000: K3 CPSW: nuss_ver: 0x6BA01901 cpsw_ver: 0x6BA80101 ale_ver: 0x00294104 Ports:8

/net/eth-uclass.c:489- eth_initialize() No ethernet found.

从 am65_cpsw_phy_init ()函数来看、使用较新的 DM-architecture 的变化从~10个月前开始：

static int am65_cpsw_phy_init(struct udevice *dev)
{
	struct am65_cpsw_priv *priv = dev_get_priv(dev);
	struct eth_pdata *pdata = dev_get_plat(dev);
	struct phy_device *phydev;
	u32 supported = PHY_GBIT_FEATURES;
	int ret;

	phydev = dm_eth_phy_connect(dev);
	if (!phydev) {
		dev_err(dev, "phy_connect() failed\n");
		return -ENODEV;
	}

	phydev->supported &= supported;
	if (pdata->max_speed) {
		ret = phy_set_supported(phydev, pdata->max_speed);
		if (ret)
			return ret;
	}
	phydev->advertising = phydev->supported;

	priv->phydev = phydev;
	ret = phy_config(phydev);
	if (ret < 0)
		dev_err(dev, "phy_config() failed: %d", ret);

	return ret;
}

感谢获得此功能的提示。

更新2.

我的三个网络接口现在可以正常工作。我将复位 GPIO 放在 MDIO 节点下、而不是 phy-nodes 下。现在看起来像这样：

&cpsw9g_mdio {
	status = "okay";
	reset-delay-us = <20>;

	cpsw0_phy0: ethernet-phy@0 {
		reset-gpios = <&main_gpio0 8 GPIO_ACTIVE_LOW>;
		reg = <0>;
		compatible = "ethernet-phy-ieee802.3-c22";
		ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_75_NS>;
		ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_75_NS>;
		ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
		ti,min-output-impedance;
	};

	cpsw0_phy4: ethernet-phy@4 {
		reset-gpios = <&main_gpio0 9 GPIO_ACTIVE_LOW>;
		reg = <4>;
		compatible = "ethernet-phy-ieee802.3-c22";
		rx-internal-delay-ps = <1>;
		tx-internal-delay-ps = <0>;
	};

	cpsw0_phy5: ethernet-phy@5 {
		reset-gpios = <&main_gpio0 10 GPIO_ACTIVE_LOW>;
		reg = <5>;
		compatible = "ethernet-phy-ieee802.3-c22";
		rx-internal-delay-ps = <1>;
		tx-internal-delay-ps = <0>;
	};
};

此主题可以关闭。
