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:
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.
