Port on Board DDR Chip on QorIQ T1&2 Series
FSL(Now is NXP) used DIMM slot on T1040RDB and T2080QDS board. And my company first customized board used DIMM also.
But, due to the reliability, we decided change DIMM slot to on board DDR chip, so I need make it work.
The fsl support one powerful tool named ‘Code warrior’ and it has a plugin named ‘QCVS’. We can validate DDR configurates by it. See Ref.4 for more information.
After validate, we should make some change to U-Boot.
First add ‘CONFIG_SYS_DDR_RAW_TIMING’ defined in board config.h file.
