MX6DQP DDR3 Script Aid

[#1]

This is a tool can generate a DDR3 script easily for i.Mx6DQP and only need input several parameters based on using DDR datasheet and system architecture.

Following docs(English or Chinese version) are also can be referred as a hand on guide.

Thanks

Could you please share the DDR stress test tool link for iMX6 Dual plus &  iMX6 Quad plus.

Hi Sir,

Is need to add those setting into imx6qp.cfg file ?

//For i.mx6qd parts of versions A & B (v1.0, v1.1), uncomment the following lines. For version C (v1.2), keep commented
setmem /32	0x021b08c0 =	0x24912489	// fine tune SDCLK duty cyc to low - seen to improve measured duty cycle of i.mx6
setmem /32	0x021b48c0 =	0x24914452

Hi Apollo,

The script aid is general reference for script developping.

About fine tune registers, user should adjust according dedicated board design.

Please refer to EB828 for more detailed.

Seems you already find it.

Hi,

could you please add 16bit bus width?

Thank you very much

[LinWang]

I am not sure what kind of application only need 16bit DDR on i.MX6DQP?

Whatever,below aid support 16bit conifguration and can be referred.

Hi,

thank you very much. Well, we are trying QuadPlus instead of Solo, so the bus is still 16 bit wide ...

[nexy_sm]

Hi, just another short question:

In Excel sheet I am not able to choose QuadPlus. Are Quad and QuadPlus identical in this situation?

[LinWang]

Hi,

For I.MX6DQP_DDR3_Script_Aid_V0.01.xlsx, you can choose QP or DP.

For I.MX6DQSDL DDR3 Script Aid V0.10.xlsx, you can't because it is not created for QP.

Just refer to 16bit configuration and migrate into your QP script manually.

For example, create 16bit and 32bit script based on I.MX6DQSDL DDR3 Script Aid V0.10.xlsx can comapre the different.

Then apply the different into 32bit script generated from I.MX6DQP_DDR3_Script_Aid_V0.01.xlsx.

Hope above proposal can help you.

BTW, please take care of i.MX6QP need much larger power supply than i.MX6S.

Hi,

Does the i.MX6/7 DDR Stress Test Tool V2.80 support the i.Mx6DQP calibration?

Can I select in TARGET field MX6DQ for performing calibration?

Thank,

Aviad

[oferausterlitz]

Hi,

can you please advise on the above?

There is no MX6DQP option in the NXP DDR Test Tool.

Should calibration for the i.Mx6DQP be done by selecting MX6DQ in TARGET field?

Thanks.

Aviad

[LinWang]

Sorry for late response due to Public Holiday!

Please contact local support team for double confirm.

For me, I think it is ok to select 6DQ for 6DQP chip.

Hi LinWang,

Currently we encountered iMX6QP+DDR3L calibration fail, I used MX6DQP_DDR3_Script_Aid_V1.01.xlsx and DDR3 Stress Tester V3.00 to do test but failed at calibration stage. The USB device disappeared when I did calibration….

The part number of DDR3L is V73CBG08168RFPJ11I

Please give us suggestion.
