Please help me to resolve this issue. I am using 16GB UDIMM.

Current TFA boot software does not support UDIMM 18ADF2G72AZ-2G6E1. Our software team is aware of this problem and is working on solving this issue.

Meantime try to use following sw patch, it relates to file \plat\nxp\soc-ls1088\ls1088ardb\ddr_init.c.

Following code needs to be changed:

--------------

static const struct board_timing udimm[] = {
{0x04, rce, 0x01030508, 0x090b0d06},
};

-------------

After change:

-------------

static const struct board_timing udimm[] = {
{0x04, rce, 0x01030508, 0x090b0d06},
{0x0F, rce, 0x01030508, 0x090b0d06},
};

-------------

Thank you Bulat, your suggestion is working fine. Now I can able to boot LS1088ARDB_PB through SD Card booting and I can run main Ubuntu on the platform.

Currently I am facing some other issue. 

I have loaded all images in one of the SD Card through flex-installer. That SD card is working as it suppose to work.

But when I am trying to make another SD card image through flex-installer, i cannot able to make another SD card bootable image.

Do you have any procedure/document to make SD Card bootable image through flex-installer. I may need information from formatting the SD card onwards.
