Hi, I'm looking for suggestions on how to solve a boot-up process on a custom LS1046A board I'm working on. I'm using the LSDK 21.08 platform, and have enabled debugging, as well as added code to track progression through the stages of the boot-up process, and I'm not able to make my way into u-boot.
The output from my diagnostic terminal looks like this:

I don't understand the value of the Arguments.
It also looks like u-boot gets it's information about DDR4 from the TF-A code, so I don't see why this wouldn't work.
Also, since BL2 and BL3 are running (which looks like they're running from DDR4) I don't see why u-boot wouldn't run as well.
Can somebody point me in the right direction? Has anybody else run into this type of behavior?
Any input is helpful. Thanks.
