Hi Team,

As I understand, the boot loader is being passed with the DDR configuration parameters.

Does the boot loader takes care also the calibration & memory training sequences during initialization?

Or any tools/steps that needs to be followed outside the boot flow?

Hi,

In the u-boot directory: arch/arm/dts/k3-j721e-ddr-evm-lp4-4266.dtsi

All the DDR related configurations are in the dtsi file. R5 SPL makes use of that DTS file and configures the DDR.

Hope that clarifies. If no further questions please click on verify answer.

Best Regards,
Keerthy
