I set the same DDR parameters in each document(I.MX6DQSDL DDR3 Script Aid V0.10.xlsx,I.MX6DQSDL DDR3 Script Aid V0.11.xlsx)
However, there are differenct value of the output as shown below.
*I.MX6DQSDL DDR3 Script Aid V0.10.xlsx
setmem /32 0x021b0008 = 0x09444040 // MMDC0_MDOTC
*I.MX6DQSDL DDR3 Script Aid V0.11.xlsx
setmem /32 0x021b0008 = 0x24444040 // MMDC0_MDOTC
I set the same DDR parameter, but I don't know why this value is different.
What is the correct value of MMDC0_MDOTC register?
