Linux kernel update problem via SDCARD on BOARD (via U-Boot)

[SBae.4]

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)

 

What is problem? ^^;;

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

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

And I want to buy stm32mp157c-dk2 board but it is out of stock.

When is it available and does it have production planning?

If it isn`t until April, I should buy stm32mp157a-dk1.

Hi @Community member​ ,

Indeed stm32mp157c-dk2 are no longer produced and replaced by stm32mp157F-dk2 with 800Mhz support capability.

You should indeed buy a dk1 ( a @650 or d @800 ) if you don't care about security and Wifi / BLE module

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.
