Hi Ganesh

for new memory it is necessary to run ddr test (also use i.MX6ULL_LPDDR2_Script_Aid )

i.MX6/7 DDR Stress Test Tool V3.00 

and update uboot *.cfg file with new ddr calibration coefficients found from test

mx6ul_14x14_evk\freescale\board - uboot-imx - i.MX U-Boot 

then adjust uboot #define PHYS_SDRAM_SIZE in

mx6ul_14x14_evk.h\configs\include - uboot-imx - i.MX U-Boot 

Best regards
igor
