i.MX6 UltraLite EVK - bootloader issue with SD card

Question asked by mickaeltoumi on Nov 26, 2015



I am trying to get u-boot booting from a SD card (32GB) on the i.MX6 EVK. I loaded the SD card with a u-boot that I built through the Yocto project (see attached). I followed the documentation called "i.MX_6SoloLite_EVK_Linux_User's_Guide.pdf". My environment is MacOSX with a virtual machine running through VirtualBox.


Before loading the bootloader on the SD card I formatted the card with the SDFormatter application.


Following Freescale documentation I issued the command below to load the bootloader only:


sudo dd if=u-boot-imx6ulevk.imx of=/dev/sdb1 bs=512 seek=2 skip=2 conv=fsync


After setting up the serial and turning ON the EVK I am getting "0x00" on the serial port. Resetting the platform with the SW2102 button the result is the same.


What could be the issue? I expect to see u-boot traces starting up.
