Hi,

I have Micron LPDDR4 SDRAM Type is MT53E768M32D2(attach spec file 200b_z2bm_ddp_s_lpddr4_53E.pdf).
MSCALE_DDR_Tool seems doesn't support this type dram. I use MX8M_LPDDR4_RPA_v22.xlsx to generate .ds file
that never reference ADDRMAP_ROW_B16(ADDRMAP7). In my understanding this dram type need use more than MX8M_LPDDR4_RPA_v22.xlsx's
default row bits. If not ,MX8M_LPDDR4_RPA_v22.xlsx how to fit in this dram type. If yes, Did any new update RPA.xlsx
for this dram. Thanks.

Hi,

   This is my using 24 RPA.xlsx logout info(Z2BN_12G_2_1_24_17_10_3_32.log). And success embedded those gen code (ddr_init & ddrphy_train)in my system. But there is some problem for access memory space. There can't reach over 2GB space in this solution. In my logout info there shows "Total density detected on the board is: 1536MB ",, Does that correct? Any way I stand corrected..Thankful.
