Hi, Can anybody share DDR parameters used for initialization of FRWY Kit as captured by QCVS DDR tool?

See attached file. This file is available in NXP LSDK2012 or LSDK 2004 Linux BSP.

Use the following paths:

/packages/firmware/atf/plat/nxp/soc-ls1046/ls1046afrwy

and

/packages/firmware/atf/plat/nxp/drivers/ddr/fsl-mmdc

What should be DQ Mapping ??  I have connected discrete DRAM and mapped DQ0 to DQ63 to Data pins of DRAM in 1:1 fashion. should it be DQ_0_3 is 0x00 and DQ_4_7 is 0x21 or should it be DQ_0_3 is 0x00 and DQ_4_7 is 0x00. I have mapped DQ(0:7) to DQ(0:7) data lines of DRAM.

Use the LS1043ARDB board as example:

Discrete DRAM is used on this board.
