AM620-Q1: Issue with USB DFU Boot on AM62x SK Board: Kernel Panic (VFS: Unable to mount root fs on unknown-block(0,0))

Tool/software:

Hi Team,

I am using the USB DFU mode to boot the Linux image on an AM62x SK board, following commands have used. I have utilized pre-built images, specifically the Image and am62-sk.dtb files from the pre-built binaries.

Steps followed:

setenv dfu_alt_info "k3-am625-sk.dtb ram 0x90000000 0x300000"
dfu 0 ram 0
DFU prompt - dfu-util.exe -a 0 -D k3-am625-sk.dtb

setenv dfu_alt_info "Image ram 0x93000000 0x3500000"
dfu 0 ram 0
DFU prompt - dfu-util.exe -a 0 -D Image

bootm 0x93000000 - 0x90000000

However, during the boot process, I encounter the following error, and the booting process halts:

[ 3.484870] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Could you please confirm steps which i am following is correct booting Linux image AM62x SK board using USB DFU mode?

Thanks & Regards,

Hello,

Looks like filesystem is not mounted in the boot media.

What is the boot media being used here?

Refer here: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1127618/faq-sk-am62-how-to-flash-emmc-using-usb-dfu-on-am62x-sk-e2

Hi Aparna,

We have used OSPI boot mode & once u-boot is up, we alt the u-boot & using USB-DFU for loading & Booting from RAM.

Yes, you will have to mount root filesystem in OSPI flash.

One quick way to test using SD card is to flash the wic image and use SD card as boot media to see if your Linux images boot.

But if the goal is to be able to boot completely from OSPI, you will have to create a ubifs image and flash it into your mtd partition in OSPI, I cannot provide the steps to the above method right away. You can refer to the following documentations as required.

Thank you for your quick response.

Is it Possible to give the steps for booting Prebuilt Linux Binaries through UART or USB DFU method? Currently we don't want to flash the linux images into storage devices(OSPI-Flash).

We took the linux binaries from below path

ti-processor-linux-sdk/board-support/prebuilt-Images

Image
k3-am625-sk.dtb

Thanks & Regards,

Hi,

To boot using USB DFU, follow the steps documented here: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/08_06_00_42/exports/docs/linux/Foundational_Components/U-Boot/UG-DFU.html

Hi Aparna,

we have Linux images and working Uboot for UART/USB DFU mode, Also we have TFTP options available.

can you give us steps to do TFTP Linux image to Eval board ?

Thanks & Regards,

Hi Aparna,

Thank you for your reply.

We want steps to Boot Linux binaries through UART/TFTP. hope our query is cleared.

We need only steps for Booting the Linux OS image through TFTP/UART any of one Mode.

Note: Currently we don't want to flash our images in storage media.(No Emmc,No SD card, Not required for Flash)

Hi,

You will have to create an initram fs image to boot kernel via Ethernet or DFU

Steps to create, load and use a .cpio-formatted rootfs image to boot Linux from U-Boot: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1176944/faq-linux-how-to-boot-sitara-am3x-am4x-am6x-devices-from-initramfs-cpio-archive-ram-disk

Hi Aparna,

Sorry, i was on leave last week.

Thank you for sharing the steps

I followed the approach below through USB-DFU:

Reference: [FAQ] Linux: How to boot Sitara AM3x/AM4x/AM6x devices from initramfs (.cpio Archive, RAM Disk) - Processors forum - Processors - TI E2E support forums

Option 2b: Load a standard cpio image in U-Boot and pass it directly to the Kernel through initrd=

Procedure i followed for USB-DFU

setenv dfu_alt_info "k3-am625-sk.dtb ram ${fdtaddr} 0x300000"
dfu 0 ram 0
DFU prompt - dfu-util.exe -a 0 -D k3-am625-sk.dtb

setenv dfu_alt_info "Image-am62xx-evm.bin ram ${loadaddr} 0x3500000"
dfu 0 ram 0
DFU prompt - dfu-util.exe -a 0 -D Image-am62xx-evm.bin

setenv dfu_alt_info "tisdk-tiny-initramfs-am62xx-evm.cpio ram ${rdaddr} 0x1000000"
dfu 0 ram 0
DFU prompt - dfu-util.exe -a 0 -D tisdk-tiny-initramfs-am62xx-evm.cpio

=> setenv args_initramfs 'setenv bootargs console=${console} ${optargs} initrd=${rdaddr},0x${filesize}'
=> run args_all args_initramfs
=> booti ${loadaddr} - ${fdtaddr}

I used the tisdk-tiny-initramfs-am62xx-evm.cpio image from the SDK/filesystem folder and the k3-am625-sk.dtb and Image-am62xx-evm.bin binaries from the prebuilt images folder.

However, we are encountering an error while booting the linux image & attached the logs

=> printenv fdtaddr
fdtaddr=0x88000000

loadaddr=0x82000000
