AM5728: 内核无法启动,卡在 Waiting for root device PARTUUID=7a61ff61-02...

Part Number: AM5728
Other Parts Discussed in Thread: TMDSEVM572X

AM5728开发板,

内核无法正常启动,卡在 Waiting for root device PARTUUID=7a61ff61-02...

从启动log里可看到有一句 Kernel command line: console=ttyS2,115200n8 root=PARTUUID=7a61ff61-02 rw rootfstype=ext4 rootwait

请问如何解决?谢谢

  • 请问是使用的TMDSEVM572X板吗?是从SD卡启动的吗?是使用的SDK中预编译的image文件吗?请再次详细说明一下,谢谢!

  • 开发板是创龙的TL5728F-EVM,这个和TMDSEVM572X区别是内存只有1G,默认网口是eth1,其它外围连接都一样。

    用sdk的bin目录下的create-sdcard.sh脚本创建的sd卡后,uboot无法启动

    所以把uboot的内存修改为1G,网口修改为eth0,重新编译生成MLO和u-boot.img,替换sd卡boot分区的同名文件,rootfs分区不做任何改动。之后启动,就卡在Waiting for root device PARTUUID=7a61ff61-02...这里不动了

    但奇怪的是在uboot启动阶段,把启动方式按如下命令修改为nfs方式启动内核,则内核却可以正常启动

    env default -f -a
    saveenv
    reset
    setenv serverip 192.168.1.105
    setenv rootpath '/d/sdk-am57xx-06.03.00.106/targetNFS'
    setenv bootfile zImage-am57xx-evm.bin
    setenv ip_method dhcp
    setenv nfsopts 'nolock,v3,tcp,rsize=4096,wsize=4096'
    setenv getuenv 'mmc dev ${mmcdev}; if mmc rescan; then if run loadbootenv; then run importbootenv; fi; fi;'
    setenv bootcmd 'run findfdt; run getuenv; setenv autoload no;dhcp ;tftp ${loadaddr} zImage; tftp ${fdtaddr} ${fdtfile}; run netargs; bootz ${loadaddr} - ${fdtaddr}'

    setenv ipaddr 192.168.1.106 
    setenv gatewayip 192.168.1.1
    setenv netmask 255.255.255.0

    saveenv
    boot

    再把sd卡rootfs分区的boot目录下的zImage、zImage-am57xx-evm.bin、am57xx-beagle-x15.dtb都更新为和ubuntu 的tftpboot目录里的一样,再执行命令

    env default -f -a
    saveenv
    reset

    启动后,内核还是卡在Waiting for root device PARTUUID=7a61ff61-02..

  • 重新把SD卡的rootfs分区更改为ext4,制作文件系统,把zImage和am57xx-beagle-x15.dtb拷贝到/boot目录下,启动开发板,还是卡在Waiting for root device PARTUUID=46082b90-02...这里。

    把SD卡放在ubuntu上,用命令blkid查看

    /dev/sdd1: LABEL="BOOT" UUID="39DA-4712" TYPE="vfat" PARTUUID="46082b90-01"
    /dev/sdd2: LABEL="rootfs" UUID="02f60639-aa2d-4e29-a511-f0006b99c794" TYPE="ext4" PARTUUID="46082b90-02"

    看上去PARTUUID也都是PARTUUID="46082b90-02",但是为什么卡在这里呢?
