hi,   

  we desgin the board use imx8mm . not use evk board.  and yes , its ddr4

  I build the sdk flow thease steps:

1 setup bsp

  mkdir imx-yocto-bsp
cd imx-yocto-bsp
repo init -u https://github.com/nxp-imx/imx-manifest -b imx-linux-scarthgap -m imx-6.6.23-2.0.0.xml
repo sync

2， setup project 

 DISTRO=fsl-imx-xwayland MACHINE=imx8mm-ddr4-evk source imx-setup-release.sh -b LoRaWAN

3, build 

bitbake core-image-base

then , I get the rootfs 

here is my local.conf : 

MACHINE ??= 'imx8mm-ddr4-evk'
DISTRO ?= 'fsl-imx-xwayland'
EXTRA_IMAGE_FEATURES ?= "debug-tweaks"
USER_CLASSES ?= "buildstats"
PATCHRESOLVE = "noop"

# Switch to Debian packaging and include package-management in the image
PACKAGE_CLASSES = "package_deb"
EXTRA_IMAGE_FEATURES += "package-management"

thanks

Hello @arnold0kang 

I am not sure what is happening, but it appears that Yocto is setting a blank password on the user account.

Please try to add this to you local.conf in order to configure the user account:

# Set user account and password
APTGET_ADD_USERS = "user:password:shell"
#  format 'name:password:shell'.
#    'name' is the user name.
#    'password' is an encrypted password (e.g. generated with
#    `echo "P4sSw0rD" \| openssl passwd -stdin`).
#    If empty or missing, they'll get an empty password.
#    'shell' is the default shell (if empty, default is /bin/sh).

Please try it.

Best regards,

Salas.

Hello @arnold0kang 

I hope you are doing well.

Could you please share the steps that you did for this compilation?

Also, Could you please share the content of your local.conf file? 

Also, are you using the EVK? if yes, is the LPDDR4 or DDR4?

Best regards,
