Read SPD Fails on QorIQ Configuration Project

[smiller2]

I have a new design with a blank QSPI, so there is no RCW.   I cannot get the Bare Board bring-up to run because the DDR DRAM is failing.   I tried to read the SPD with a QorIQ Configuration Project.   However, that does not work either.   I put a scope on the I2C lines going to the DIMM and they never toggle.    When I try to Read the SPD, the TX/RX LEDs on the Code Warrior flash, so I know that hardware got the commands.

Code Warrior is

Version: 11.5.2
Build Id: 210130

The error messages in the Wizard are shown below.    It appears from the python code that those messages reference, that it is trying to do an additional reset since it thinks there is a valid RCW loaded.  However, there is not!      I cannot find a setting in the project to tell it to use a safe RCW. 

In the Bare Board project,  if I diagnose the debugger connection, then it fails at DDR Init and fatally fails at the DDR Write to 0x80000000

Questions:

1.  What am I missing or doing wrong to read the SPD?

2.  Is there a way to by-pass the DRAM test in the Bare Board debugger to at least be able to program the QSPI so the RCW is present? 

Thanks.

1. Please set the switch setting on your custom board to configure the target board  as "hard-coded" RCW, then execute reading SPD in QCVS tool.

2. In CodeWarrior initialization file, the flash programming algorithm is configured to run in OCRAM, so you can comment the DDR controller initialization section in CW initialization file when do flash programming.

For flash programming, please refer to the following procedure.

(1). Please refer to "3.2 Working with bareboard application" in C:\Freescale\CW4NET_v2020.06\CW_ARMv8\ARMv8\Help\Getting_Started_for_CW_ARMv8.pdf to create a bareboard project and connect to the target board. Please modify CW initialization file as the following before connect to the target board.

In Target Connections panel, please click "board(1)"->Target Initialization File, please modify 

"USE_SAFE_RCW = False" to "USE_SAFE_RCW = True" and please comment "Init_DDRC(DDR_freq)".

(2). Please refer to the section "7.7 Using flash programmer from eclipse IDE " in C:\Freescale\CW4NET_v2020.06\CW_ARMv8\ARMv8\Help\PDF\ARMv8_Targeting_Manual.pdf to do flash programming.

Thank you.

I tried placing the RCW configuration to both 0x9F and 0x9E which I believe are the hard-coded values.  Neither one would allow me to read the SPD.    I got the same error.    Before doing that test, I changed the SPD I2C address to 0x51 from my default of 0x50.     When I changed the RCW configuration back to QSPI,   then the SPD read started working.    I can read the SPD  and it configures the DDR Controller.  However, I cannot view the SPD data.   I am using the document linked below:

https://www.nxp.com/docs/en/user-guide/QCVS_DDR_User_Guide.pdf

When I click on the "..." button, then another window opens up and says,  "No SPD data found for the selected DDR component!

How do I view this SPD data?  

Having configured via SPD,  then I tried DDR Validation.   However, that failed too.   Centering the Clock fails with just a statement of Endianness.   However,  I don't know where to configure this to fix it. 

Thanks.

The SO-DIMM I am using is 16GB ECC since that is what the end customer requires.   I have run the validation numerous times and it always fails the same way.    "Write leveling start values are OK, but test failed for other issues"     I did the dump from the command line.   However,   I do not see anything in this that suggests what failed.    Below is the dump:

Thanks.

I  switched to a known good X64 single rank DIMM to eliminate ECC from the mix.    It still fails the same way.  However, I got it to pass validation  by setting the DRAM speed in the DDR Bus Clock of 1066MHZ inside the DDR Block of Processor Expert even though the RCW has the clock set to 800MHZ.     I realize that this should not work and that the warning boxes say the clocks should match.  However, if they match, then it never passes DDR Init.    If I have this mis-match, then it passes init and passed validation.     If I then take the settings from validation and attempt to apply them to Target Configuration of Code Warrior,  it still will not pass Init .  However, now the only failure is an Address Parity error.  

Attached is a zip file that contains a memory dump of the DDR area for both the failed Target Configuration and the successful validation.     Other than the errors,  the memory dumps are identical.   This seems to indicate to me all registers are configured correctly.    This seems to suggest that the Init routine being performed by Validation is different that the ones included in the Target Configuration. 

Also in the Zip file is a DDR Report generated at the end of the successful validation.    It should be noted that there appears to be a software bug in generating that report.   If you compare the DDR Registers in the report to the Dump file of the registers, you will see that the SDRAM Mode register is incorrect in the XML DDR Report. 

Questions:

1.  Why is this passing validation ONLY when the DDR clock rates are mismatched between the PLL setting and the DDR Controller?  

2.  Where can I get a copy of the Initialization sequence being run by the Validation since that one works and the samples in the Target Configuration files do not?

Thanks.

After completing DDRv validation, please click Project->Generate Processor Expert Code, then refer to ddrCtrl_1.py file under Generated_Code, which can be used in Target Initialization file.

Just to be clear,  I did check the DDR clock with a scope at the DIMM module.   It is definitely running at 800MHZ there.    It stays at the frequency regardless of whether I am running the Target Configuration or the Validation.

DDR Validation is still the gating item on this project.   The DIMM does appear to work fine, since by trial and error, I was able to set DRAM parameters that would allow the bootloaders, U-Boot and Linux to all execute fine.   Yet, the Processor Expert cannot validate and time this DIMM. 

Sometimes the Read SPD works, other times it fails.  Today,  I was making another attempt to validate and time the DIMM.   When I read the SPD,  I found it was failing again.    This time I discovered that I could click on the red "X" and get fail info.   Attached is a screen shot.   It shows that while it claimed the SPD Read failed, there is actual SPD data present.
