We are working with an LX2160ARDB reference board and attempting to use a 32GB DDR4 RAM module on the DDR1 controller. However, in CodeWarrior's DDR Memory Controller Configuration, we couldn't find an option for a 32GB device under DRAM Configuration per Device.
Could you please provide guidance on:
- How to configure the DDR Memory Controller for 32GB RAM on the LX2160ARDB?
- Steps to validate the 32GB DDR RAM on this platform.
- Instructions for updating the firmware (if necessary) to support 32GB DDR RAM.
Hi Yiping,
We have loaded the RCW file(rcw_2000_700_2900_19_5_2_sd.bin) into SD card and in DDR configuration panel, when Read SPD is done we are getting as "Unsupported raw card revision. Set the CLK to DQS skew values manually."
To configure 32GB DDR4 RAM on your LX2160ARDB, as CodeWarrior lacks a direct option, you'll need to use the **NXP QorIQ Configuration and Validation Suite (QCVS)**. Obtain your 32GB DIMM's detailed specifications (density, ranks, device width) and input them into QCVS to generate custom DDR controller configuration code. This code must then be **integrated into the U-Boot bootloader** source from the latest Layerscape Software Development Kit (LSDK). After building U-Boot, **flash the updated firmware** to your board. Validate the 32GB RAM by checking U-Boot boot messages and using Linux commands like `free -h` once the system boots.
- In DDR configuration panel, please select "Read SPD" and "DIMM" as Configuration mode, then click "Read SPD" to read parameters from SPD and finish the DDR project creating.
- After creating QCVS DDR project, please check all "Validation stage" and "Operational DDR tests" to to connect to the target board to finish all the validation.
Please refer to QCVS DDR Tool user manual

- No need specific firmware when doing validation with QCVS DDRv tool.
