Hi,

I use stm32mp157a-dk1 board and sdcard boot.

Host PC is win10, virtualbox and ubuntu 20.04.1

I try this example but have some problem.

https://github.com/STMicroelectronics/meta-st-stm32mp/blob/dunfell/recipes-kernel/linux/linux-stm32mp/README.HOW_TO.txt

I don`t have folder "/media/$USER/bootfs/" and media/$USER/rootfs/lib/modules/

My board complete this step.

But error occurs this command .

/media/sh/bootfs/ is not directory. (*'sh' is my user name)

    Hi @Community member​ ?

    When proceed to :

    STM32MP > ums 0 mmc 0

    A new USB "STMicroelectronics USB Download gadget" should be visible in your Virtual Box. Please check it's not connected windows side.

    You should get something like :

    PC $> ls -l /dev/disk/by-partlabel/

    total 0

    lrwxrwxrwx 1 root root 10 Feb 8 08:57 bootfs -> ../../sdb4

    lrwxrwxrwx 1 root root 10 Feb 8 08:57 fsbl1 -> ../../sdb1

    lrwxrwxrwx 1 root root 10 Feb 8 08:57 fsbl2 -> ../../sdb2

    lrwxrwxrwx 1 root root 10 Feb 8 08:57 rootfs -> ../../sdb6

    lrwxrwxrwx 1 root root 10 Feb 8 08:57 ssbl -> ../../sdb3

    lrwxrwxrwx 1 root root 10 Feb 8 08:57 userfs -> ../../sdb7

    lrwxrwxrwx 1 root root 10 Feb 8 08:57 vendorfs -> ../../sdb5

    and :

    $ ls -al /media/$USER/

    total 15

    drwxr-x---+ 6 root root 4096 févr. 22 05:36 .

    drwxr-xr-x  3 root root 4096 déc. 15 05:48 ..

    drwxr-xr-x  6 root root 1024 févr. 5 03:31 bootfs

    drwxr-xr-x 19 root root 4096 févr. 5 03:36 rootfs

    drwxr-xr-x  7 root root 1024 févr. 5 03:31 userfs

    drwxr-xr-x  4 root root 1024 févr. 5 03:31 vendorfs

    Hi, @Community member​ 

    I connected USB in Virtual Box but keyboard is stopped in kernel folder(install_artifact) console.

    And at the moments, board is reboot and kernel folder console is available.

    So I can`t command ls -l /dev/disk/by-partlabel/ cuz can`t use keyboard.

    What is problem? T.T

    Hi @Community member​ ,

    I'm afraid this is purely related to your VirtualBox environment for which I can not help much.

    Double check and try to get help on some dedicated community.
