Hi,

i'm trying to initialize my DDR3L using the values generated by DDR3 script aid v0.10, but i'm not able to read any registers by jtag.

The SDRAM model is MT41K512M16_DDR3L_8Gb_x16_2CS_TwinDie_V80A

I configured the script as:

Is it correct? I have the dought about the chip select.

In the schematic i see the  i.MX6Q - DDR module has only DRAM_CS0 connected to CS0 and CS1 MT41K512M16 module.

I see if i use the configuration of Nitrogen6x board, i'm able to read and write the registers.

 

Thanks
