How to use ddr tools to configure 3GDDR

Hi ALL:

I have ever used ddr tools to generate 1G and 2GDDR configure file ddr_init.c and ddrphy_train.c for I.MX8M and works well.

Now I need to configure 3GDDR file ,the ddr tool will calibration and gen code success . but when i make a new imx-boot and burn it into the SD card , it will stuck in kernel stage . the only difference is the DDR size， so， I think the ddr_init.c and ddrphy_train.c may error.

Is there a problem with my configuration?

i will modify follow files on uboot when modify DDR size

board\freescale\imx8mq_evk\ddr\ddr_init.c

board\freescale\imx8mq_evk\ddr\ddrphy_train.c

include\configs\imx8mq_evk.h PHYS_SDRAM_SIZE

We have in place a document that explains how to use the DDR tool, and we have an excel file that help you to select the proper values regarding your memory, here is the link: i.MX8 MSCALE SERIES DDR Tool Release (V2.10)

Have a great day,
