SD card boot problem

[masa_yamamoto]

Hi,

I've made a SD card image (.sdcard) using bitbake.  I used Linux dd command to write it to SD card.  I inserted the SD card to the SABRE board but it does not boot.  It should not be SABRE board issue because it boots from another SD card which was bundled in the SABRE design package.   My understanding is that the .sdcard contains U-boot even though I cannot read it by mounting /dev/mmcblk0p*.

Do you have any suggestion how I debug?

Hi again,

More information about configuration here.

I posted SD card image file name, local.conf, fdisk -l result.

Hi Masayuki,

which sabre board and SD slot are you using? Did you try another SD slot(s)? I would also suggest to try loading the image in Windows using Win32DiskImager

[masa_yamamoto]

Hi Jan,

Thank you for your suggestions.  Yes, I just tried Win32DisImager and result was same (no boot).

I use i.MX6 quad SABRE board for auto.  The board has only one SD slot, so no chioce.

Are the board switches in the following configuration?

(S1) 0100100000 (from 1-10 bit)

(S2) 0010 (from 1-4 bit)

(S3) 0010 (from 1-4 bit)

[masa_yamamoto]

S1, S2 ... Same

S3 0011 (from 1-4 bit)

I just change S3 to 0010 and tried, but no change (no boot)

Hi Jan,

I think it is not SABRE board issue because it boots from another SD card which was bundled in the SABRE design package.   Do you have any suggestion?  I'm trying to find more clue.  The only warning message I got from bitbake is about Ubuntu version.  I'm using Ubuntu 16.04.1 LTS because 14.04 has a graphic UI problem on my machine.  I don't know this information helps.

Yes,

the problem might be in the Ubuntu version. 16.04.1 LTS is not tested and may cause issues when building. I would suggest to try to build an image using 14.04 version. Since only terminal is required, the GUI problem should not be any concern.

[masa_yamamoto]

I've tried Ubuntu 14.04 version and resolved the issue.

Thank you.
