[chandraevolute]

Hi,

i built core-image-base and succesffully flashed onto SD Card and booted as root.

but i am unable to execute reboot,poweroff,shutdown commands.  

below my terminal log

root@melange:~# poweroff
poweroff: must be superuser.
root@melange:~# reboot
reboot: must be superuser.
root@melange:~# shutdown -r now
shutdown: warning: cannot open /var/run/shutdown.pid
shutdown: /dev/initctl: Permission denied
init: must be superuser.
root@melange:~#

am surprised that when i logged in as root i do not have have full permission? something wrong with the bitbake?

Hello,

  Yes, minimal configuration is supported for i.MX6 UL ; Qt 5 images are only

supported for i.MX SoC with hardware graphics. They are not supported on the
i.MX 6UltraLite

Have a great day,
Yuri

finally i have built core-image-base and the rootfs is around 72 MB. This is fine with us. I used imx-3.14.38-6UL_ga version. We are not using any GUI related stuff. Thank you Yuri

Hey Chandra,

Could you please share the build configurations for building core-image-base?

Thanks,

Thank you so much for the answer!

Can you please share the command lines you used as well? I am also looking to build the base version without any GUI but with all the other functionality (pingpong code for example).

And if possible the procedure you use to loading the image, SD or directly.

Thanks,

Evgeny

bitbake core-image-base is the command that I gave. I am using  imx-3.14.38-6UL_ga bsp version. I am using SD card.

Thanks
