Create SD card to boot MCIMX6SX-SDB board issue

Hi,

 

I am trying to create SD card to boot but failed.

 

Hardware:

MCIMX6SX-SDB

i.MX 6SoloX SABRE Development Board|NXP 

 

1.When using the out-of-box 8GB SanDisk SD card with EVB(With Linux_L4.1.14 1.0.0), the board can be boot and log can

    be find from UART terminal.

2.I downloaded the i.MX 6SoloX Linux Binary Demo Files from below URL, file name is L4.1.15_2.0.0_iMX6SX(REV L4.1.15_2.0.0)

Embedded Linux for i.MX Applications Processors|NXP 

3. Following the document to create the SD boot card:

    a. Following 4.3.3 Partitioning the SD/MMC card from the i.MX_Linux_User's_Guide.pdf to setup the partitions.

    b. Copying a bootloader image by using

         sudo dd if=u-boot-imx6sxsabresd_sd.imx of=/dev/sdd bs=512 seek=2 conv=fsync

        Have checked the SD card is sdd by using cat /proc/partitions command.

    c. using this card, still cannot boot. keep the hardware unchanged and use the out-of-box 8GB SanDisk SD card with

        EVB, the board can be boot.

4. Please kindly check attached files for more information,

 

Would you please help to check:

1.Which u-boot file should be used for boot the MCIMX6SX-SDB board, am I using the correct one?

2.The dd command writes RAW data in the card, how to confirm the u-boot data is successfully written into the card?

3. I also try copy the zImage and *.dtb file in the sdd1 partition but still failed. But I think this step is not needed because uboot can start without kernel files.

 

Please kindly let me know if you need more details.

 

Thanks!

 

Best regards,

Lei
