Hi, I want to do LPDDR2 Stress testing on imx6solo custom board. So will you please provide .inc file or any other utility for doing this. DDR Used is MT42L16M32D1HE-18
FIrstly, You do not need to modify the RPA .inc file. Just set the right DDR parameter is OK.
And the RPA file thay i have sened to you is no issue follow your DDR type. So please check your DDR layout is no problem.

hi, @deepaktajanpure
what do you mean enable chip select? what is your each step?
I just enabled CS0 using below line
setmem /32 0x021b0000 = 0x82010000 // MMDC0_MDCTL
which was not there in your previous script
Hi, @deepaktajanpure
What so you mean not enabled any chip select? you can see the RPA file.
After enabling Chip Select I'm getting same error as I posted below. Calibration fails again
hi, @deepaktajanpure
PLease use the attachment file, And also check your PCB design if is folllowing the HDG file.
But you have not enabled any chip select in this script. Will you please check it again?
Still calibration is failing. Please go through below logs and inc file attached herewith

Error: failed during ddr calibration
Hi
your excel sheet is for imx6sx. Excel sheet version is older v1.1, we are using 1.4. sheet is defined for different LPDDR part number (MT42L256M32D2) ours is MT42L16M32D1HE
hi, @deepaktajanpure
Please share your ddr tool setting windows.
Hi, executed file sent by you, but still same problem. It is getting stucked in calibration. Please see the logs shown below
