We are customizing LS2085A RDB u-boot from EAR6 release to our custom board. We have discrete DDR4 on our custom board. We ran DDR validation suite on our custom board. We used the stable timing parameters to initialize our board. The u-boot stops in RAM relocation. When we enable both the DDR controllers, it stops with "Synchronous Error Handler".
Please let us know if we have to do any special customization for discrete RAM setup.
