Hello everybody!
Is there a chance someone have configuration file (flash_header.S) for iMX6 Dual Lite connected with DDR3 RAM Memory (2 x MT41J128M16HA)
MMDC should be configured for DDR3 x32.
Thanks in advance!

Hi Rafal,
Basically, you need to modify two register fields in the original flash_header.S in order to support 32-bit DDR3.
1. Change the memory bus size to 32-bit by set DSIZ on MMDC1_MDCTL register to 1.
2. Disable the ODT on higher 32-bit by clearing MMDC2_MPODTCTRL register.
