I am working on i.mx6ul based custom board. We want to added support of New DDR MT41K256M16TW on i.MX6ul in a replacement of older DDR3.i.e MT41K256M16TW-107AIT:P
We have taken the ref of the pico-imx6ul-emmc board. It has MT41K256M16HA-125:E
Also swapped the datalines as one to one ( i.e DRAM_DATA0(uc) <--> DQ0(DDR), DRAM_DATA1 <-->DQ1, DRAM_DATA2 <-->DQ2.....DRAM_DATA15 <-->DQ15) , previously it was differently mapped in the ref board.
For such change is need to change in the bootloader ? For DDR interface in software ( uboot) which changes need to do and where ?
