Wrong Image Format for bootm command

Category: Software
Software Version: CCES-2.10.0,Ubuntu-20.04

I followed the steps for uboot in the ADSP-SC573 using the following start guide


https://wiki.analog.com/resources/tools-software/linuxdsp/docs/quickstartguide/quickstart_sc573


When utilizing the image file (fitImage) that is utilized in the start guide, it functions effectively.

consequently, I used zImage, which is found in the source folder itself, in place of that image.


This error was triggered,


Wrong Image format for bootm command

Error: can't get kernel image


I am very curious how to proceed on that....

  • Hi Sushindren,

    bootm command is for Uimage

    As you were using zimage, you need to use bootz command.

    replace the bootm command from your bootargs to bootz and give it a try.

  • Hi Prasanth,

    I can't get you properly, Are you told to boot with sdcard boot option.

    When i am using printenv in the uboot, it shown some arguments,

    Here as you can see i loaded the zImage in the imagefile when run sdcardboot i shown same error, i dont know where i am missing,

    If i can't get your point kindly tell elaborately,

    Thankyou,

  • Hi Sushindren,

    Could you share the exact complete error along with the command you were passing to the u-boot?

    Do you zImage copied under /boot/Zimage directory of the SD card? 

    could you print the output of # ext2ls mmc 0:1 /boot

    Thanks,

  • Hi Prasanth,

    Apologize for the late reply,

    As you mentioned i executed the command,

    => ext2ls mmc 0:1 /boot                                                         
    <DIR>       4096 .                                                              
    <DIR>       4096 ..

               18488 sc573-ezkit.dtb                                                
    =>

    when i run sdcard boot its showing wrong image format, i followed the same procedure which was in the link

    here i used zImage for this.

    => run sdcardboot                                                               
    switch to partitions #0, OK                                                     
    mmc0 is current device

  • Hi Sushindrean,

    It seems your u-boot environment variable was modified,

    ```

    #setenv sdcardboot 'mmc rescan; mmc dev 0 0; ext2load mmc 0:1 ${loadaddr} /boot/${ramfile}; ext2load mmc 0:1 ${dtbaddr} /boot/${dtbfile}; run sdcardargs; bootz ${loadaddr} - ${dtbaddr}'

    #run sdcardboot

    ```

    Thanks,

  • Hi Prasanth,

    Thank you for your support, now its booting partially

    In the end it can't able to load the .ldr as well as .db files.

    platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
    remoteproc remoteproc0: core1-rproc is available
    cfg80211: failed to load regulatory.db
    remoteproc remoteproc1: core2-rproc is available
    remoteproc remoteproc0: Direct firmware load for adi_adsp_core1_fw.ldr failed with error -2
    ALSA device list:
      No soundcards found.
    remoteproc remoteproc0: powering up core1-rproc

    remoteproc remoteproc0: request_firmware failed: -2
    remoteproc remoteproc1: Direct firmware load for adi_adsp_core2_fw.ldr failed with error -2

    I think most of the files has loaded this one only a trouble maker for me.

    Waiting for your reply from your end.

    Thank you,

  • Hi Sushindren,

    Could you reach the userspace login prompt?

    I hope that remoteproc won't be an issue. 

    Thanks,

    Prasanth R

  • Hi Prasanth,

    No i didn't get the login prompt.

    It showing like this only and also i can't able to give any commands it's giving the same symbol.

    Thank you,

  • Hi Sushindren,

    This seems strange on seeing this basic boot issue,  

    step 1: 

    I recommend following this

    #env default -a -f

    #run sdcardboot

    If the above doesn't help

    step2:

    I recommend you to follow the below link and build the minimal image, replace the complete u-boot and boot the device with the newly created image

    Thanks,

  • Hi Prasanth,

    Thankyou for your great support , i followed your recommendation of the steps which first step didn't worked for me.

    In the second recommendation i used the minimal and fitimage which is mentioned in the quick start guide that one worked for me

    but when i incorporate zImage and minimal image it causes and stuck in between while booting itself, i didn't get the login promt also

    I surfed regards with this issue also and i found one link and followed the same steps still i am getting the same.
