TI中文支持网Part Number:AM5728Other Parts Discussed in Thread:TMDSEVM572X
自制开发板，连接方式和TMDSEVM572X一样，用预编译的zImage,从SD卡无法启动，但却能从nfs启动
谁能告诉我这个问题的可能原因？解决思路是啥？附件是log，谢谢

Nancy Wang：
请尝试将以下配置从mmc1节点去除已禁用UHS，以防导致上面启动日志中看到的 sdhci 故障。
vmmc-supply = <&vdd_3v3>;vqmmc-supply = <&ldo1_reg>;
,
qingyulan：
我把内核arch\arm\boot\dts下的am57xx-beagle-x15.dts文件的如下地方注释掉（其它相关设备树里未找到与mmc1的vmmc-supply相关的），重新生成设备树，拷贝到SD卡rootfs分区的boot目录下启动，内核报错，见附件

日志里有这么一句：sdhci-omap 4809c000.mmc: 4809c000.mmc supply vqmmc not found, using dummy regulator
4809c000正是文件dra7.dtsi里描述的mmc的地址，能从这里找到什么线索吗？谢谢
,
qingyulan：
在am57xx-beagle-x15-common.dtsi文件的 &mmc1处添加如下两行
vmmc-supply = <&vdd_3v3>; vqmmc-supply = <&ldo1_reg>;
内核启动log最后变成如下，然后就不动了
