The current pad DSE for QSPI is 60ohm. This setting cause too strong drive to clock and data signals. Need to change the DSE to 120ohm for better signal quality.

How to use U-Boot on Freescale MX6UL 14x14 EVK ----------------------------------------------- - Build U-Boot for MX6UL 14x14 EVK: $ make mrproper $ make mx6ul_14x14_evk_defconfig $ make This will generate the SPL image called SPL and the u-boot.img. - Flash the SPL image into the micro SD card: sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync - Flash the u-boot.img image into the micro SD card: sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync - Jumper settings: SW601: 0 0 1 0 Sw602: 1 0 where 0 means bottom position and 1 means top position (from the switch label numbers reference). - Connect the USB cable between the EVK and the PC for the console. (The USB console connector is the one close the push buttons) - Insert the micro SD card in the board, power it up and U-Boot messages should come up.
