Rich Chen
Expert 4170 points
Part Number: AM67

Tool/software:

Dear champ, 

Customer need to complete SI (Signal Integrity) test for PCIe on customer board. 

Recommendation on how to enter compliance mode / RX loopback mode so customer SI team can do signal measurement. (eye diagram?)

    Hi Rich,

    Please expect a delay of 1-2 days in responses due to TI US holiday.

    Rich,

    We will get back to you on this.

    and what is the background, would CCS be ok?

    Shreyas,

     

    Usually Window is the first choice but AM67x will be running Linux from customer side.

    In test lab, there could have computer running Windows to control DUT to enter test mode for compliance test. 

    Execute file or application will be preferred. 

    UART console and commend line is less preferred. 

    CCS installation and JTAG will not be considered unless that's the only way to test. 

    This applies to USB3 and PCIe and all other SI test.   

    Please provide Linux commend line instruction. 

    CCS is the final solution if there is no alternative.

    Hi Rich,

    For entering compliance mode, you could refer to the TRM register sheet for the PCIe and search for link_ctrl_status register EC bit which enables the device to go into compliance.

    In Linux, registers in general can be written with devmem2. Our team has not validated entering compliance mode through Linux, but should be able to write to the register using "devmem2 0x0D0000F0 w 0x10". Usually eye diagram measurement is done through baremetal code and/or using CCS instead of Linux.

    Hi Rich,

    Could you try "devmem2 0x0D0000F0 w 0x11" instead of 0x10?

    Takuma, 

    Customer feedback using devmem2 0x0D0000F0 w 0x11, not seeing any output on PCIe interface. 

    Is there additional setting required other than this register? 

    May you provide the BareMetal test code for reference?

    Takuma. 

    Customer doesn't reserve JTAG on their board and expect having Linux comment to conduct this test. 

    Using devmem2 0x0D0000F0 w 0x11 doesn't see any waveform output even with 50 ohm loading on test fixture. 

    Could team verify the Linux test procedure with AM67x EVM in house?

    Hi Rich,

    Internally, PCIe compliance is verified with baremetal only. We do not have Linux test procedure.

    Takuma,

    It seems modifying single register is not enough and we need the procedure to enter test mode. 

    Could team create a Linux version procedure for field customer to use?

    Hi Rich,

    I can take a look at it, but as this is not supported in our standard SDK, please expect this to take a long time.

    I am still asking to get access to the source code, so I have no timeline to share yet. But depending on how complex the source code is, it may be a 1 week task, or a several month task.

    How other TDA4 customer conduct PCIe compliance test? 

    Is there instructions in Linux for TDA4 customers?

    Hi Rich,

    Rich Chen said:

    Customers can conduct PCIe compliance test using baremetal code.

    Rich Chen said:

    Is there instructions in Linux for TDA4 customers? 

    No, there are no instructions in Linux.

    On the other hand, I do see you have a different thread for AM64 asking a similar question here: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1486766/am6442-how-to-enter-pcie-compliance-test-mode-on-am64x

    ^ Were you able to test this out? The serdes and PCIe controller should be similar between AM64 and AM67. If this procedure for AM64 works, then the same apply to AM67. 

    Regards,

    Takuma

    TI__Expert 4170 points

    Takuma, 

    No, the AM64x post also mentioned same register bit to set and it doesn't work either. 

    We do need a way to initial PCIe compliance test because there is no JTAG reserved on customer board. 

    We can try on TI EVM if a Linux or console version can work. 

    One thought on the bare metal test code, can we create a file which can run the test code from SD card? Customer usually will reserve SD card for SW developing.

    Hi Rich,

    I have been looking through the source code and so far it looks to be a bit more complicated to go convert to Linux commands. Can I get 2 more days to see how feasible it is to port?

    Rich Chen said:

    The bare metal test code runs in emulation mode on EVM while Linux runs in normal mode, so I do not think it is possible to use the bare metal binary as-is. And since it uses some libraries from PDK that is specific to R5, it will not compile easily for A53 cores.

    Takuma, 

    I checked the source but I could not find the commends inside project. 

    Have you luck to get the code convert to Cortex A with Linux? 

    BR, Rich

    TI__Guru 51313 points

    Hi Rich,

    The entry point is main() in serdes_diag_test_main.c, which calls Serdes_Example_BERTest() in serdes_diag_test.c.

    So far, no luck in converting to Linux. I was trying to convert by referencing the code and register excel sheet, but there are too many registers to look through in a short amount of time. I was thinking a week might be enough, but it is looking to be more in the range of a month or more to convert.

    Takuma, 

    Per we discussed over E-mail, the last update for this test can refer another thread for AM64x and we are expecting a simple solution which customer can do TX mode test. A loader in SD card or script in Linux will be feasible.  

    https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1486766/am6442-how-to-enter-pcie-compliance-test-mode-on-am64x/5780274#5780274

    Hi Rich,

    I talked with a different colleague internally, and it sounds like entering compliance test is simpler than expected.

    • No additional software is needed. There is no need to program any register
    • To enter compliance mode:
      • There must be no activity on receiver lines
      • There must be impedance on the transmit lines
      • ^ to achieve above two points, there is a PCIe card that allows you to connect to scope which has a button that cycles through different PCIe gen speeds and de-emphasis configuration. I think you may already have this
      • When link training is initiated with above states for the RX/TX, and when SoC is configured as RC, it should go to compliance mode
    • The example that we have sent in the past is one that requires a BERT to generate signals

    Regards,

    Takuma

    Takuma, 

    I was in customer lab for PCIe compliance test which I sent the setup picture to you. 

    There is a PCIe card (call test fixture) connect all the signals back to Oscilloscope. 

    Oscilloscope will keep measure signal from test fixture. They took another system and power on the DUT and I saw waveform and test pattern on Oscilloscope. 

    Connecting our device will show any output at beginning then we power up and run Linux and not get any output on Oscilloscope at all. 

    I tried the CCS Binary from team via JTAG and it does run the test program run on R5 to place AM67x PCIe into PMA Isolation but still not seeing output on Oscilloscope.  

    When you said 

    • No additional software is needed. There is no need to program any register 

    What software are running on AM67x? How can I enter compliance mode? 

    For the example binary you sent requires BERT, do we have a another example binary can do TX mode test (without BERT)? This is for CCS and JTAG.

    • When link training is initiated with above states for the RX/TX, and when SoC is configured as RC, it should go to compliance mode
    • The example that we have sent in the past is one that requires a BERT to generate signals

    If considering Linux, we need to configure PCIe controller to RC mode in Linux, when and how to place PCIe to compliance mode? What software to run?

    Hi Rich,

    Kyle (who is our hardware application team manager) sent an email internally. Current top priority is the other thread on USB, and Shreyas will be responding with some experiments to try. Next priority would be this thread for PCIe.

    For PCIe, we are working on trying to get a hardware set up similar to the one that you have sent a picture of.

    As for your questions:

    • This should work with Linux
    • PCIe should enter compliance mode during link training automatically, if there is no activity detected on RX, and TX is terminated

    We are trying to verify this at our end.

    Regards,

    Takuma

    Takuma, 

    Thanks for the arrangement to verify TX mode test without BERT. 

    I used TI EVM with pre-build WIC image which will set PCIe in RC mode. 

    Let me know what the step we can enter compliance mode automatically during link training. This is what I was told from PCIe expert here.

    Hi Rich,

    Good news, but we are able to verify that we can enter compliance mode on TI EVM without BERT.

    Software used:

    Hardware used:

    • CLB (Compliance Load Board)
    • Teledyne LeCroy LabMaster 10 Zi-A Oscilloscope (high frequency oscilloscope)

    Procedure:

    1. Connect TX Lane 0 of CLB to oscilloscope like below

    2. Flash default Linux image onto SD card and boot. No extra patches or commands are needed. Just boot the default Linux. Logging in is optional.

    3. Done. There should be a signal observed on the oscilloscope

    Logs:

    If there are no signals, then we have collected some logs which you can cross check to see if there are any differences.

    And as a sidenote, we have also tried switching between the different compliance modes. We were successfully able to switch between Gen1 speeds, Gen2 speeds, and Gen3 speeds.

    However, this requires an extra hardware configuration step which is to connect  COMP TOGGLE signal on the CLB to RX0 like below:

    And there is a switch on the CLB that can be pressed to toggle between different speeds.

    This is not required if just testing PCIe Gen1 speeds, and even without these connections there should be Gen1 speed signals coming out of the TX lines.

    Regards,

    Thanks Takuma.

    The scope captures for PCIe compliance using the Linux SDK, J7AEN EVM, and the PCIe compliance load board are attached for Gen1, Gen2 and Gen3 .

    Gen1

    Gen2

    Gen3
