Hello,
I'm trying to get the 'Interactive DDR debugging' (FSL DDR> prompt) working with our LS1043ARDB development board. I have more than a month of experience working with the SDK 2.0 (plus patch) with this development board.
Some slides from our NXP training state the CONFIG_FSL_DDR_INTERACTIVE conditional compile flag must be set, and rebuild u-boot. Is this necessarily for the default build?
I found a README.fsl-ddr file in this directory:
./build_ls1043ardb/tmp/work/ls1043ardb-fsl-linux/u-boot-qoriq/2016.01+fslgit-r0/git/doc
It states two different ways to enable the FSL DDR debug prompt (set environment variable, and/or press 'd' on reset), and neither of them work.

@Jerry Morrow I define environment variable <ddr_interactive> as fellow:
setenv ddr_interactive 1
saveenv
reset
then can entry DDR debug mode automatic.
i can't entry DDR debug mode by entry "d"
see reference doc: README.fsl-ddr

I set ddr_interactive = 1 and enabled the common debug option for uboot and still do not get to the ddr debugger prompt.
This option is enabled in default configuration of the LS1043ARDB u-boot.
Attached file contains the LS1043ADRB u-boot configuration file and screenshot if 'd' is pressed during u-boot starting.
Have a great day,
