Linux boot failure: "mount: mounting proc on /proc failed: No such file or directory"

John Cook34
Intellectual 570 points

Having downloaded the following SDK, I am trying to boot Linux on the Keystone 2 EVM using pre-built components within the SDK.  

ti-processor-sdk-linux-k2hk-evm-02.00.01.07-Linux-x86-Install.bin

Linux boot fails with the error message "mount: mounting proc on /proc failed: No such file or directory" and additional error messages (excerpt below; full earlyprintk attached).

/cfs-file/__key/communityserver-discussions-components-files/791/3482.2016_2D00_03_2D00_23_5F00_earlyprintk.txt

I'm using the following components:
from the ti-processor-sdk-linux-k2hk-evm-02.00.01.07/board-support/prebuilt-images folder:
k2hk-evm.dtb, skern-k2hk.bin, zImage-k2hk-evm.bin


from the ti-processor-sdk-linux-k2hk-evm-02.00.01.07/filesystem folder:
arago-base-tisdk-image-k2hk-evm.tar.gz

Are any of the above components incompatible with each other or with the Keystone 2 EVM?

Thanks,
John

    Hi John,

    Please ensure that the correct filesystem is used to boot. Are you working on NFS, ramfs or ubifs booting?
    From the above message, I understand that rootpath variable is empty which means filesystem path is not defined in u-boot.

    There are plenty of threads discussed in e2e on this issue. I recommend you to search on e2e for solutions. Please get back to us if you can not solve issue.

    Thank you.

    Dear John,
    The problem seems to be problem with permission issue in filesystem.

    Can you please set full permission to filesystem (files & folders) ?

    chmod 777 -R filesystem

    Titus, I did as you suggest but the failure mode is the same.

    Thanks,

    Raja, I am using ramfs.  I have previously been able to boot Linux without defining the rootpath variable in u-boot.  Does u-boot use reasonable defaults when the variable is undefined?

    Here is the value of bootargs:

    bootargs=console=ttyS0,115200n8 rootwait=1 earlyprintk rdinit=/sbin/init rw root=/dev/ram0 initrd=0x802000000,30M ip=192.168.168.25:192.168.168.2::255.255.255.0:tmac-evm:eth0:off panic=1

    u-boot retrieves the following files via FTP to the following addresses:

    getfdt=tftp 0x87000000 k2hk-evm.dtb
    getfs=tftp 0x82000000 arago-base-tisdk-image-k2hk-evm.cpio.gz
    getkern=tftp 0x88000000 uImage-k2hk-evm.bin
    getmon=tftp 0x0c5f0000 skern-k2hk.bin

    All of those files are from ti-processor-sdk-linux-k2hk-evm-02.00.01.07-Linux-x86.  Are the target addresses correct?

    Unpacking the filesystem, I see that the /proc directory is empty.  Should it contain something?

    Thanks,

    John

    You won't see anything in proc directory for filesystem, it is (proc) pseudo filesystem, it would create while booting.

    Titus, the first sign of failure I see is "mounting proc on /proc failed".  Does this mean that the boot sequence failed to create the pseudo filesystem?  What's the next step for debugging this?

    Dear John,
    Can you please do UBIFS booting from NAND flash ?
    I've tried the NAND boot with UBI image given by TI processor SDK package, didn't get any problem.
  • 0 in reply to Titusrathinaraj Stalin
    Intellectual 570 points

    Titus, I will try to run UBIFS from NAND flash as you suggest, but it's important that I also implement TFTP booting using ramfs because our application will use it.  Is this a use case TI Linux does not intend to support?  

    Thanks,
    John

    No.
    I will also try RAMFS booting and update you.

    Thanks, Titus.  Getting this running will be a huge step forward for our project.

    I tried to update the EVM for UBI as follows but something went wrong:

    - rename  to keystone-evm-ubifs.ubi on the TFTP host

    - from u-boot:
       tftp ${addr_ubi} ${name_ubi}
      run burn_ubi
      reset

    Here's the result:

    TCI6638 EVM # tftp ${addr_ubi} ${name_ubi}

    Please make sure that you are using appropriate u-boot on your board.
    Use processor SDK u-boot.

    u-boot# env default -a
    u-boot# setenv ipaddr 10.100.1.10
    u-boot# setenv serverip 10.100.1.20
    u-boot# saveenv
    u-boot# run get_ubi_net

    Dear John,

    I was able to boot RAMFS along with zImage using processor SDK package.

    The following boot command and args I used to do boot the RAMFS.

    I have rebuilt the kernel along with RAMFS files and folders. (I built kernel image with initramfs )

    make menuconfig ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

    General Setup ->

      Initramfs source file(s)   -->

    Provide the location where you have filesystem.
