Download the images into the MMC on Ubuntu12.04

[jerrylee008]

when I Download the images(IMX6Q) into the MMC on Ubuntu12.04，

I used cmd ：$ sudo dd if=u-boot.imx of= /dev/sdx bs=1K seek=1; sync
but I can not find /dev/sdx.

I have found mmc\SD card can not be loaded under Ubuntu12.04 system，
But I can use the MFGTOOS in Windows to download the firmware to the board

May I ask what is the reason？
How can i solve it?

try lsblk or df to find your /dev/sdx

you can use sd card reader, insert card to the reader,   then use  sudo fdisk -l,  the pc will  list your sd card, sdb or sdc,

then use   dd if=

Thanks  a lot! But I used command “sudo fdisk -l”   I can not find sdb or sdc！

Please tell me what to do next，

ps：I can download firmware on Windows successfully with MfgTool

sdx means sd partition you use, like sdb,  for more detailed informatio, you can refer to the chapter 4.3.1 Preparing the card of imx linux user guide.

pls focus on the chapter 4.3.1 Preparing the card and chapter 4.3.2 Copying the full SD card image
