部件号：TPS6.5217万

您好，

我有一个自定义主板，它一直在启动内核...

U-Boot 2020.01-00001-g5704c41f23-dirty (Mar 18 2022 - 19:02:07 +0800)

我发现定制主板上的VDD_MPU为1.1V，但我希望它应该是1.26V，就像TI-EVMSK一样。(事实上，在AM335x-evmsk上测量后，它是1.31V)

这可能是导致我的主板cat无法进入内核的根本原因。

以下是修改AM335x-evmsk.dts的步骤，

1.将I2C从属ID从0x2D修改为0x24

2.修改TPS节点

您好，Woody：

感谢您使用E2E！您的问题似乎与AM335x软件/内核有关，因此我将把此E2E重新分配给处理器团队。

谢谢！

您好，Woody：

这是否与下面的主题中讨论的问题相同？如果是，我们可以关闭此对话并继续讨论以下主题吗？

您好，Bin，

是的，它是相同的自定义板。您能否在关闭之前回答问题？

是否允许在u-boot阶段中dcdc2_reg (VDD_MPU)的值为1.1V？

这可能是自定义主板启动失败的原因吗？

如果我想将VDD_MPU从1.1V拉至V1.26V，我该如何操作？

注：我已在u-boot的AM335x-evmsk.dts中对其进行了描述。

		dcdc2_reg: regulator@1 {
			regulator-name = "vdd_mpu";
			regulator-min-microvolt = <925000>;
			regulator-max-microvolt = <1351500>;
