i.MX 6QP SD Card Boot Problem

[jpe1313]

I am new to the NXP community and so I previously posted in the general community page. I am reposting here.

I have the SABRE board for smart devices  6QP.  I need to have the SDcard have the "core-image-base."

I used the Freescale Yocto Project User's Guide, Rev. L_3.14.38_6ul-ga, 09/2015 and successfully build the image and got all the files in ..MYNAME/tmp/deploy/images/imx6qsabresd.

I imaged the SD card as in Section 6.1:

THE DISK UTILITY SHOWS:   (Partition 2 has /bin /home, etc.)

But when I boot I get the following messages:

*****************************************************************************

THANKS IN ADVANCE

Hi Janet,

How you have created the SD card ?

The best way is "dd if=<path_to _generated_image> of=/dev/mmcblk* bs=4M" (* is 0, 1, 2, ...) or for windows exist Win32DiskImager tool.

Also you need chcek the setings of u-boot env with command "printenv" in u-boot shell if you have correct setings of boot arguments (SD card number)

Martin / Anyone,

Thanks.   I did create the SC card as described.   YES I BELIEVE THAT it is the u-boot arguments.  So, I am looking into that.  I have not used u-boot much at all. 

So, I am reading about it (getting interrupted a lot). 

I noticed that I was not using the latest Linux User's Guide for my board so I followed the instructions for REV. L4.1.15_1.0.0-ga, 03/2016 and got a new .sdcard image.   When I use that I see that is trying to boot it wants to boot from the NET.

Does anyone have the setting for the SD card for u-boot to boot locally?   I'll be looking in the Linux User's Guide, but any help would be appreciated.

Hi Janet,

Here you can use the mfgtool to download the images to SD card and then boot up from the SD card. About the mfgtool download you can refer to the section 4 Booting Linux OS in i.MX_Linux_User's_Guide.pdf.

Any questions you can contact me.
Have a great day,
Rita

Rita,

So, my problem was a bad SD card.  I've been up and running.  Now the next step is to take what I have on the SD card and get it onto the EMMC chip so I can boot from there.  I've got the MCIMX6Q-SDB evaluation board (imx6qsabresd).  I've read what you suggested.  I am posting another question about Using the eMMC to get some clarification. "Using eMMC on MCIMX6Q-SDB  (i.MX SATBE boards)"

Thanks.
