Hi ,
Basing on ti-ezsdk_dm814x-evm_5_05_02_00, my custome board repalced the DDR3 as 4 pcs of MT41K128M16JT-125 IT K.
I am trying to following such likes. but most disappearred or cannot be downloaded.

Would you provide the the full files and step to let me try to generate the DDR relavent parameters for ddr_defs_ti814x.h like below
