i.MX 6 UltraLite and eLCDIF in u-boot

Did anybody successfully test LCD module on uboot-imx (2015.04_3.14.38_6ul_ga)? We have the custom board based on IMX6UL EVK and we are unable to send something on LCD screen.  All what we did in uboot software compared to EVK was to provide our LCD parameters (30MHZ clock, etc.) and set LCD_EN signal, but unfortunately clrlogo and bmp display commands show nothing. The signals characteristics look properly such as the data is being constantly sending.


Is there something which we should take into account while connecting LCD to eLCDIF in u-boot?


Thank you in advance for engagement in this issue.
