STM32MP151c内核找不到rootfs怎么解决？

124 rootfs

问答对人有帮助，内容完整，我也想知道答案 0 我有一个基于 STM32MP151c 的定制板，上面有一个 eMMC（没有 SD 卡）。在U-Boot中成功找到eMMC，分区如下： part list mmc 0 Partition Map for MMC device 0 -- Partition Type: EFI Part Start LBA End LBA Name Attributes Type GUID Partition GUID 1 0x00000400 0x000013ff "ssbl" attrs: 0x0000000000000000 type: 8da63339-0007-60c0-c436-083ac8230908 guid: 81ae02b5-e823-4dfa-909e-f18021275bd7 2 0x00001400 0x000213ff "boot" attrs: 0x0000000000000004 type: 0fc63daf-8483-4772-8e79-3d69d8477de4 type: linux guid: 8691f7b3-c55d-4979-ad45-ab006af4d469 3 0x00021400 0x000293ff "vendorfs" attrs: 0x0000000000000000 type: 0fc63daf-8483-4772-8e79-3d69d8477de4 type: linux guid: c1241248-0452-4a9d-a181-dd26b1b8dc4a 4 0x00029400 0x001a93ff "rootfs" attrs: 0x0000000000000000 type: 0fc63daf-8483-4772-8e79-3d69d8477de4 type: linux guid: e91c4e10-16e6-4c0e-bd0e-77becf4a3582 5 0x001a9400 0x0075fbff "userfs" attrs: 0x0000000000000000 type: 0fc63daf-8483-4772-8e79-3d69d8477de4 type: linux guid: 91050ee0-2f8c-4a37-b0b1-54b16dfb2ec8 在启动之前，我将 bootargs 设置如下： setenv bootargs root=PARTUUID=e91c4e10-16e6-4c0e-bd0e-77becf4a3582 rw console=ttySTM0,115200 但是，内核找不到 rootfs 分区： [ 3.256832] VFS: Cannot open root device "PARTUUID=e91c4e10-16e6-4c0e-bd0e-77becf4a3582" or unknown-block(0,0): error -6 [ 3.266412] Please append a correct "root=" boot option; here are the available partitions: [ 3.274832] 0100 65536 ram0 [ 3.274837] (driver?)

答案对人有帮助，有参考价值 0 实际上，在挂载 rootfs 时找不到 MMC（竞争条件）。所以 cmd 行中的 rootdelay 解决了这个问题（暂时）。
