Hi sir,
We are using dm8127 custom board through the reference of DM8127-CSK evm module.
In the evm module DDR3 (MT41K256M16TW ) 2-chip selects & 4 modules used default.
in our custom board DDR3 (same IC) 1-Chip select & 2 module(Lower & Higher data) used.
Reference AM335x_starterware we tested DM8127 EVM module of DDR3 It's working.
In custom board it's not working we changed the DDR3 configuration setting because same configuration not working in this board(Same DDR3 IC's but single Chip Select here)?

while(RD_MEM_32(DMM_LISA_MAP__2)!=0x0);
while(RD_MEM_32(DMM_LISA_MAP__3)!=0x0);
i changed for less size.
but its failing read & write for DDR3.
Any changes required in the code side, Could you give me some suggestions.
Thanking you,
Regards,
Ramachandra
