LS2088ARDB How I can use ProcessorExpert DDR to validate my DDR

benoitmasse — Thu, 21 Jan 2021 03:07:55 GMT

Hi,

First, I used the original code in NOR flash and the original DDR.

I used Processor Expert to retrieve the actual Data from my ls2088ARDB.

Import DDR controler 1 and 2 from target, and import PBL, Read from Target.

Than I run the first test and it failed. (Write-Read Compare)

I want to use this tool to integrate Micron 18ASF2G72AZ-2G6E2, but I cannot do basic thing with the actual. Any help will be appreciate.

Please refer to https://community.nxp.com/t5/Qonverge-Knowledge-Base/DDR-Controller-Configuration-on-LS2085-LS2080-Bringing-up/ta-p/1128310

You need to create a QCVS DDR project with the method "reading from SPD", then use DDRv tool to connect to the target board to initialize DDR controller, validate and optimize the DDR configuration by gradually refining.

I did that, my problem it's when I'm trying to validate the second controller.

If I activate one controller with one UDIMM 18ASF2G72AZ-2G6E2 (DDR_Controller_1) everything is fine.

When I do the same process with both Controller (1 and 2) with two UDIMM 18ASF2G72AZ-2G6E2, The validation cannot find the right WRLVL value to start.

I got a similar problem when I adapt the DDR for "Target Initialization File" for Target Connection.

I take the ddrCtrl_1,py and ddrCrtl_2.py generated by the tool (QCVS) and add them to the "Target Initialization File". Run the "Diagnose connection" and the test failed the first time. Then I added the following lines

CCSR_LE_M(0x1080000 + id * 0x10000, 0x7ff)
CCSR_LE_M(0x1080008 + id * 0x10000, 0x7ff)
CCSR_LE_M(0x1080010 + id * 0x10000, 0x0)
CCSR_LE_M(0x1080018 + id * 0x10000, 0x0)
CCSR_LE_M(0x1080080 + id * 0x10000, 0xa8050422)
CCSR_LE_M(0x1080124 + id * 0x10000, 0x1c70071c)

for each Controller (id = 0 or 1),

With these modifications the "Diagnose Connection" pass with out error (Target Connections View). Then DDR is programmed correctly.

See the code in attachment file (Micron32G_targetinitialisation.py).

I tried to change the 3FF to 7FF for both controller in the tools (QCVS DDR) but no luck.

Any suggestion ?

After creating a QCVS DDR project with reading from SPD method. Please configure "Device" value as "DDR_Controller_2", "DDR Bus Clock" as 933MHz(according your target board) in Properties panel. Please refer to the attachment.

Then in the Validation panel perform "Centering the clock" validation.

If your problem remains, please open CCS(CodeWarrior Connection Server) console, type "log v", then connect to the target board and capture the CCS console log to me to do investigation.

In addition, would you please send your QCVS DDR project to me, I will connect it to my demo board to do more verification?

benoitmasse — Tue, 26 Jan 2021 00:29:44 GMT

CCS console, I'm running under ubuntu 20.04 (linux) and I cannot figure out how to enable console neither than run "log v".

I made a special Workspace with all the code and configuration that I use to test Memory, (One UDIMM or 2 UDIMM ,

I tested connection with the target (In "Target Connections" with USE_SAFE_RCW = True, Connection file is "LS2088A_RDB Benoit V2 G32").

I tested Baredboard in DDR and in OCRAM, everything are fine.

I tested DDR "Centering the clock" with Micron16G (One UDIMM), is OK.

I tested DDR "Centering the clock" with Micron32G (Two UDIMMs), is Not OK.

What thing to mention is, the DDR controler (1 and 2) are programmed in interleaving mode.

It's the reason I had to add 0x7FF instead of the 0x3FF in the "Target Initialization File".

I discussed this issue with the application team, please refer to the following feedback from them.

This issue is tool related and we are in process of determining a fix. for now, Customer can configure each controller individually first. then when running the two controller in QCVS tool bypass (gray out) the auto search (the first cell/table) in the centering the clock test and that will resolve the issue for running validation with two controllers enabled.

Re: LS2088ARDB How I can use ProcessorExpert DDR to validate my DDR

benoitmasse — Wed, 27 Jan 2021 03:50:13 GMT

Thanks for the answer,

But How can I bypass (grey out) the auto search ?

Select the gray square icon to de-select all the cells (inverted queued cells)
Select the white square with gray dashed boarder icon to select a cell or drag to select a group of cells. To select more cells select the same icon again.
To clear all selections, select the blue square icon.

benoitmasse — Thu, 28 Jan 2021 05:23:11 GMT

I select to queue all tests (or cells) in Centering the clock scenario except the Autos eaerch.

All tests run well but only with my first controller DDR_mc1.

When I start the test with the second controller, DDR_mc2, the test stop right away with any message.It

Is it normal ?

Re: LS2088ARDB How I can use ProcessorExpert DDR to validate my DDR

yipingwang — Fri, 29 Jan 2021 01:28:38 GMT

Please start a new project and just test the DDR_mc2.

If this is a board bring up. make sure to check, voltage (GVDD/VREF/VTT), clock(input clock, PLL setting in RCW, and output MCK), reset (the DRAM reset signal needs to match the assertion and de-assertion of the HRESET signal).

also check the DQ_MAP registers. so that the correct mapping is used.

I have verified LS2088ARDB works well with QCVS on both DDR controllers.

benoitmasse — Fri, 29 Jan 2021 05:38:42 GMT

FYI: I'm using the eval board ls2088ardb, with the two UDIMM UDIMM 18ASF2G72AZ-2G6E2 for 32Go.

These UDIMMs came with the eval.

I followed your instructions to enable controller 2.

I made a new project.

Configure the controller 2 alone.

In "Component Inspector -DDR" view.

I selected "Validation stage" then Start Validation.

Centering and Read ODT passed.

Write ODT and Operation DDR test failed.

I joined two files, one for controller 1 (all tests passed) and one for controller 2, with some failed.

yipingwang — Fri, 29 Jan 2021 08:41:15 GMT

When you create a QCVS DDR project for the 2nd DDR Controller following new project wizards, in "DDR configuration" panel , please configure "2nd DDR Controller", select Configuration mode as "Read SPD", please refer to the attached screenshot.

I have connected my LS2088ARDB demo board to verify the 2nd DDR Controller validation, all passed.

ufedor — Mon, 08 Feb 2021 06:44:01 GMT

At the end of January new version of QCVS (4.23) was released.

Could you please update, create new QCVS project and run the DDR Tool Validation?

Re: LS2088ARDB How I can use ProcessorExpert DDR to validate my DDR

benoitmasse — Thu, 18 Feb 2021 13:26:39 GMT

I updated the tools.

Then I created a new project, I read configuration from target (not from SPD) for both Controllers and run the tools.

All validation tests have been passed successfully.

But I did not try the eye tests.
