how to allocate data line for imx8qxp using ddr3l

[kshengyang]

hi：

   May I ask how to allocate data line for imx8qxp using ddr3l?In the imx6 series, the DQ[15:0] of the CPU and the DQ[15:0] of the DDR3 are not one-to-one。

Hi Ksheng

mapping can be performed using RPA (*.xls) tool (tab "BoardDataBusConfig")

is the same way as for i.MX8MQ processor:

i.MX8 MSCALE SERIES DDR Tool Release (V3.10) 

Please obtain such tool for i.MX8QXP in local nxp marketing ofice.

Best regards
