DRA821U: how to boot from eMMc using sbl and run linux

Long Jiang
Prodigy 140 points
Part Number: DRA821U

Hi, Expert

SDK version: ti-processor-sdk-rtos-j7200-evm-08_00_00_12  ti-processor-sdk-linux-j7200-evm-08_00_00_05

I have booted mcu2_1 and linux with SBL on sd card, now I want to switch to eMMC to boot.

My steps are as follows

1, follow the link[FAQ] TDA4VM: How to boot TDA4VM from eMMC UDA partition using SBL in SDK 8.1

2, compile can_boot_app_mcu_rtos_mcu1_0_release.appimage in MCUSW and rename to app

3, upadte DTB, in k3-j7200-common-proc-board.dts

#bootargs = "consol=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000"
bootargs = "consol=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait"

4, use the constructappimageshlos.sh tool to convert the ATF, DTB,  kernel Image 

    I get atf_optee.appimage tidtb_linux.appimage tikernelimage_linux.appimage

5, use the MulticoreImageGen tool to combine the image of mcu2_0 and mcu2_1 into lateapp1

6, copy above files to mmcblk0p1

7, Change boot mode to eMMC boot

  • SW8: 1000_0000
  • SW9: 0000_0000

8, powerup

then I found that demo in mcu2_1 run successfully but rootfs can't start up because kernel can't find mmcblk0p1

here is the kernel log

when I change DTB as 

bootargs = "consol=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000 root=/dev/mmcblk1p2 rw rootfstype=ext4 rootwait"

it can boot from eMMC and then run rootfs from SD card.  then I type "ls /dev/mmcblk0*" and found there is no mmcblk0p1 mmcblk0p2

can you provide me with some toubleshooting ideas?

Thanks

Best Regards

    Hi Jiang,

    Can you please run ext4ls mmc 0:2 from U-boot and share the result?

    Hi Parth

    Since I can't enter uboot with sbl, I use the sd card to boot in spl mode, the log is as follows

    Hi Jian,

    Instead of using SBL to boot Linux, can you first try to boot using pure Linux boot flow and see if that is working fine?

    Hi Parth,

    I try to boot using spl, linux rootfs works, but it load from sd-card

    when I pull out the sd card, the log is as follow

    then I reboot and input this command in uboot:

    => setenv mmcdev 0

    => setenv bootpart 0

    => boot

    the log is as follow

    But when I open EMMC/rootfs, I can find the file /lib/firmware/j7200-main-r5f0_0-fw

    Regards,

    Jiang Long

    Hi, Parth

    Now I add these command in the uboot

    => setenv mmcdev 0
    =>
    => setenv bootpart 0:2
    =>
    => setenv args_mmc "run finduuid;setenv bootargs console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait"
    => saveenv
    Saving Environment to MMC... Writing to MMC(0)... OK


    =>boot

    spl boot from emmc can works

    but sbl boot still cannot find  /dev/mmcblk0p2

    Hi Jiang,

    I am guessing that R5 is holding the eMMC and it is not released. I'll try to reproduce this issue on my end. Meanwhile, can you please share the complete logs? 

    Also, what is the intent of using eMMC boot? This does not have any added advantage over SD boot. so is there any specific reason for using eMMC booting? 

    Regards,
    Parth

    Hi, Parth,

    Here is my log which use sbl to boot up on emmc

    On J7ES EVM Test Point TP82(SOM Board)  and it should be Active HIGH before WDG expires

    Also, what is the intent of using eMMC boot?

    our board will be used in the car, because the vibration is strong, so all data are stored on emmc

    Hi Jiang,

    Is this issue still open? If yes, can you please mention the current state of the issue?

    Hi Parth Nagpal

    I still dont know how to startup linux on EMMC.

    The above is all I have done. And I don't know what to do next.

    Can you implement this function on EMMC（sbl->can_boot_app->lateapp->linux） and give me a tutorial document?

    Regards,

    Jiang Long
