Hi,
I have a 'SABRE for Automotive Infotainment
Based on the i.MX 6 Series' evaluation board.
My onboard CPU is IMX6U which is i.MX 6DualLite processor.

I have succeeded in booting up this board from SD card.

I used 'LTIB' tool to build the source code on a Ubuntu 12.04 laptop.

 

A few questions:

 

1. Is there any way from U-boot to read the SD card? If yes, what is the command and SD card address?

 

2. I would like to boot up from onboard NOR or NAND flash. In other words, u-boot, kernel and file system needs to be stored over there too. Can I do that? If yes, any help file on this other than jumper setting?

 

3. I wanted to flash a customized u-boot to SD card. I looked at the community and got the following information:

              boot on SD card starts at 1k location, so I can use the following command to do that:

     sudo dd if=./u-boot/u-boot.imx of=${DISK} bs=512 seek=2

    

     I don't have a 'u-boot.imx' after 'LTIB' build. Instead, I only got the binary one, u-boot.bin. Are they the same?

 

Thanks,

 

Steven
