mx6qsabreauto | Ubuntu installation

engineer_bsp01 — Thu, 22 Aug 2019 04:29:53 GMT

Hi,

I am trying to install Ubuntu rootfs in my mx6qsabreauto target board. Referring this Installing Ubuntu Rootfs on NXP i.MX6 boards .

Now I am able boot the target, in serial console and login as both richu and root, I am unable to login through the gui login manager.

How can I enable and run it form within HDMI monitor of target mx6qsabreauto rather than in serial console?

NB:installed rootfs with debootstrap.

below is my bootargs:

Hi RICHU,

Check your uboot bootargs for serial output, this are mine:

bootargs=console=ttymxc3,115200 root=/dev/nfs ip=192.168.2.126 nfsroot=192.168.2.106:/tftpboot/rootfs,v3,tcp video=mxcfb0:dev=ldb,LDB-XGA,if=RGB666 ldb=sin0 video=mxcfb1:dev=hdmi,1920x1080M@60,if=RGB24 bpp=32
hdmi=setenv bootargs ${bootargs} video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24
