LX2160ARDB: DDR validation

[Priyaa]

Hi,

We have loaded the RCW file(rcw_2200_750_2900_19_5_2.bin) from the LSDK into SD card and in DDR configuration panel, when Read SPD is done we are getting as "Unsupported raw card revision. Set the CLK to DQS skew values manually." 

How to perform DDR validation of LX2160ARDB in QCVS tool

Hi June Lu,

After changing the switch(SW1) to SD card mode where the RCW source is present, we were able to do the validation.

Thanks for the support..

[June_Lu]

It looks like you were able to read the SPD successfully, although the screenshot is slightly different from what I see on my side.

Please set SW1[1:4] to 1001 to boot from eMMC, where the RCW source has been configured for DDR validation.

Also, please confirm that "Target Connects" shows as connected see the screen shot.

Once confirmed, you can proceed with the DDR validation.

Hi June Lu,

Following the user guide, created a project again for DDR configuration and reading of SPD has done as below

Priyaa_0-1788498272408.png

And the DIMM modules are inserted in the J14, J17 connectors of RDB

[June_Lu]

It seem your screen shot is not same as me, missing button "Back" and "Cancel".

Have you follow the QCVS_DDR_User_Guide, 1.1.1 Using DDR configuration tool?

Thanks

Diagnose Connection successfully done

And DDR configuration after reading SPD is as below

Could you please confirm whether DDR validation is started successully?

Cause I'm facing an issue that the Start Validation button is enabled but the validation getting cancelled just after the start..

[June_Lu]

This is the successful screenshot.

I used the USB to connect to the CWTAP. You need to set the Probe with correct IP address.

Could you run the "Diagnose Connection" successfully?

Hi June Lu,

Connected through ethernet and able to find LX2160A as provided in the text file

Priyaa_0-1788427814124.png

But reading SPD gives as "Unsupported raw card revision. Set the CLK to DQS skew values manually." in DDR configuration window

And how to verify the SPD values are read successfully?

[June_Lu]

(bin) 50 % delete all

(bin) 51 % config cc cwtap:10.1.66.150

(bin) 52 % show cc

(bin) 53 % source IDcode.tcl

If you could find LX2160A same as the "CCS Windows Release Build 503.0.0.220812-p0.txt".

You could proceed using ethernet connection with IP address: 10.1.66.150 for ddr validation.

Thanks

Hi June Lu,

Thanks for the support

for USB the result of the command is

(bin) 51 % findcc cwtaps
0
(bin) 51 %

and for ethernet connection

(bin) 51 % findcc cwtaps
FSL07E3D5 (10.1.66.150): CodeWarrior TAP v2
Cortex-10 Probe Tip
Boot Loader v1.0.1
Operating System v1.0.5
1

for now can we proceed further using ethernet connection for ddr validation?

[June_Lu]

(bin) 52 % show cc

0: USB open failure

There are no command converters configured

it indicates that the CWTAP cannot be detected through the USB connection.

Please check the USB cable connection and ensure the CWTAP is properly recognized by the host PC.

Also, please run the command below and share the result:

(bin) 6 % findcc cwtaps

Thanks.

Able to connect through ethernet and ping the target. Even after updating CodeWarrior to v11.5.12, reading SPD gives same as "Unsupported raw card revision. Set the CLK to DQS skew values manually."

Thank you

[June_Lu]

Please confirm the CodeWarrior version from Help → About CodeWarrior Development Studio for QorIQ LS Series (ARM v8 ISA).

Please follow the instructions in "CCS Windows Release Build 503.0.0.220812-p0.txt" to verify the connection status.

We recommend testing the USB connection first, followed by the Ethernet connection.

It seems that the IP address has changed. Could you please confirm whether you can successfully ping the target?

Hi June Lu,

We are using CodeWarrior 11.5.0 and the DIMM is original module given with the LX2160ARDB

Updated CodeWarrior with archive com.freescale.armv8.11.5.12.GA.Lin.updatesite.221209.zip for v11.5.12

Now unable to detect the JTAG

Thankyou

[June_Lu]

I followed your sequence and was able to read the SPD successfully.

Could you please confirm which version of CodeWarrior you are using? Is it CodeWarrior 11.5.12?

Also, is the DIMM an original module?

Thanks.

Hi June Lu,

After booting through FlexSPI, loaded the RCW file through tftpboot at u-boot and mmc write commands as below

=> tftpboot 0x90000000 rcw_2200_750_2900_19_5_2.bin

=> mmc dev 0; mmc write 0x90000000 8 1

=> qixis_reset sd (during this command the D19 got turned on and off)

And for DDR configuration, when reading from SPD getting as "Unsupported raw card revision. Set the CLK to DQS skew values manually."

[June_Lu]

How do you load the RCW file(rcw_2200_750_2900_19_5_2.bin) from the LSDK into SD card?

Has the D19 turned on and off?
