Hi,

I have iMX53 QSB.

I have downloaded Ubuntu VM from freescale site. Along with it a pre-built  image for iMX53 QSB board is available.

So with the help of manual I burn this image (ubuntu_start_board.bin) into 4GB SD Card with help of following command

sudo dd if=/home/lucid/Desktop/ubuntu_start_board.bin of=/dev/sdb

But I am getting following error can't get kernel image!.

Please help me regarding same. Am I missing anything while following document. I am attaching document with this post.

  According to the message from the log

"MMC read: dev # 0, block # 2048, count 6144 ... Card did not respond to voltage select!"


there is no proper card inserted to SD port 0.

Is Your SD card located there (in slot 0) ?


Have a great day,
Yuri

HI Yuri,

Thanks for valuable reply.

I changed dev #0 to dev #1 and my board just started working as of now.

I used following command to do this thing

setenv bootcmd_mmc 'run bootargs_base bootargs_mmc; mmc dev 1;mmc read ${loadaddr} 0x800 0x1800; bootm'

bootargs=console=ttymxc0,115200 gpu_nommu setenv bootargs console=ttymxc0,115200 video=mxcdi0fb:RGB24,1920x1080M@60 hdmi di0_primary root=/dev/nfs ip=dhcp nfsroot=10.2

9.240.144:/tftpboot/rootfs,v3,tcp

setenv bootargs 'console=ttymxc0,115200 gpu_nommu ${lvds}'

Though my board is booting now, to understand things correctly can you please guide me why I have to change dev #0 to dev#1 and what these above command needed.

Thanks in advance.

Looks like Your boot device is SD port 1 (0,1, ...).
And the modififation from dev #0 to dev #1 is correct

in such case.

Regards,

Yuri.
