Kernel Booting Problem

Other Parts Discussed in Thread: DRA752, PMP, DRA742

In my custom board, while kernel booting it hangs after this Waiting for root device /dev/mmcblk1p2... I am using SDK ti-glsdk_dra7xx-evm_7_00_00_04 and changed the dts file according to the board. I am using same card detect pin as in EVM.

    Hello Ganesh,

    At first please see the link  -

    You must try several options to overcome your problem:

    1. Add choosen node in DTSI file

    In 'spl_early_boot' mode the kernel boot arguments are get passed through DTB 'chosen' node. Add a 'chosen' node into dra7.dtsi file and generate the DRA7-evm.dtb file.

    chosen

    {

     bootargs = "elevator=noop console=ttyO0,115200n8 root=<rootfs> rw rootwait earlyprintk fixrtc omapdrm.num_crtc=2

     consoleblank=0  cma=64M rootfstype=ext4";

    };

    where <rootfs> can be /dev/mmcblk0p2 for eMMC or /dev/mmcblk1p2 for mmc/sd.

    2. Set mmcblk1p2 in your uenv.txt file:

    Apply the change:

    mmcargs=part uuid mmc 0 1:2 uuid; setenv bootargs "console=ttyO0,115200n8 elevator=noop root=PARTUUID=${uuid} rw rootwait earlyprintk fixrtc omapdrm.num_crtc=2 consoleblank=0 cma=64M rootfstype=ext4 snd.slots_reserved=1,1"

    Best regards,

    Yanko

    Hi Yanko,

    1. Add choosen node in DTSI file

    This chosen node is already present in this SDK.

    2. Set mmcblk1p2 in your uenv.txt file:

    After doing this, hangs at the same point and getting the below message corresponding to the change root=PARTUUID=${uuid}

    Hi Yanko,

    I have used these commands in the u-boot prompt,

    U-Boot# mmc rescan
    U-Boot# fatload mmc 0 0x82000000 MLO
    U-Boot# nand erase 0x0 0x20000

    U-Boot# fatload mmc 0 0x82000000 u-boot.img
    U-Boot# nand erase 0x80000 0x40000
    U-Boot# nand write 0x82000000 0x80000 0x40000
    I was able to write into NAND as ia m not getting any error messages while writing to NAND memory.

    And tried to boot from NAND, using nboot command and i got like this
    ** No boot device **

    And also changed the sysboot pins but even then not booting from NAND and not getting any messages from SPL or u-boot .
    Do i have to do anything else?

    Thanks & Regards,
    Ganesh

    Hi,
    Use "nand info" command to check the NAND information.
    Do "nand dump" before and after writing the data (MLO).

    In initial post, you have mentioned that you are not able to boot kernel but now with MLO & u-boot from NAND ?
    Trying to boot from MMC or NAND and kernel or bootloader ?

    Hi Titus,

    Actually while booting from MMC, i am getting some problems and it hangs at

    So i thought it may be some problem with MMC communication, so meanwhile i am also trying to boot from NAND and checking.

    It seems to be the problem with device tree file. The MMC driver is not initialized properly.
    Compare the evm dts file with your custom board dts file and make sure that you have done necessary changes on dts file as per your custom configuration for MMC.



    U-Boot# mmc rescan
    U-Boot# fatload mmc 0 0x82000000 MLO
    U-Boot# nand erase 0x0 0x20000
    U-Boot# nand write 0x82000000 0x0 0x20000

    U-Boot# fatload mmc 0 0x82000000 u-boot.img
    U-Boot# nand erase 0x80000 0x40000
    U-Boot# nand write 0x82000000 0x80000 0x40000
    I was able to write into NAND as ia m not getting any error messages while writing to NAND memory.

    And tried to boot from NAND, using nboot command and i got like this
    ** No boot device **


    You might get this issue since you have not mentioned about NAND device no.

    nboot <RAM address> <NAND device no> <NAND offset>

    After flashing the MLO and u-boot, restart the board with NAND boot settings since bootloader should boot from NAND after restart the board with proper NAND boot switch settings.
    Why do you did "nboot" command ?
    It is for kernel NAND boot after loaded the kernel into RAM.

    If you want to boot with "nboot", you also have to write/flash the kernel and then do "nboot".
    You have to read the kernel from NAND and copy to RAM then do "nboot"

    nand read 0xc1180000 0x400000 0x400000
    nboot 0xc0700000 0 0x200000

    Actually mmcblk1p2 refers to MMC1/SD card or MMC2 ?

    i have not changed any pin mux settings in the DTS file for MMC1 and changed for eMMC as in my board i am using MMC2 for it . Please find my dts file for reference in the first post. I have taken the dts file from SDK ti-glsdk_dra7xx-evm_7_00_00_04. Please check my dts file also once, even i have checked with ti evm dts file.

    And i think my on board eMMC is not working properly is that the problem?



    Use "nand info" command to check the NAND information.
    Do "nand dump" before and after writing the data (MLO).

    how to use this nand dump exactly,
    i have tried like this nand dump 0 , 0 refers to page 0 and i used this command before and after writing to MLO.
    and changed the switch settings and booted. But not getting anything.

    Thanks & Regards,
    Ganesh

    nand dump <nand offset block> <page no>

    Are you using any EVM or custom board ?
    If EVM, are you using correct default MLO and u-boot binaries of NAND flash ?
    If custom, did you modify the required changes in u-boot source ?

    HI Titus,


    Please suggest any possible solutions for this,
    [ 2.786686] Waiting for root device /dev/mmcblk1p2...

    Actually in Kernel code this message comes to console in this function, do_mounts.c
    __init prepare_namespace()

    After that line it executes this piece of code,

    while (driver_probe_done() != 0 ||
    (ROOT_DEV = name_to_dev_t(saved_root_name)) == 0)
    msleep(100);

    In this name_to_dev_t(saved_root_name) we are getting 0, hence it always stays here only

    root argument is /dev/mmcblk1p2 and in my board eMMC is not working, for environment variables storage i am using NAND Flash.

    Thanks & Regards

    Hi Ganesh,
    I strongly believe that the problem with dts file for SD/MMC changes from the following kernel logs.
    Its failing to register the MMC driver from dts.
