AM62P5: Validating peripheral interfaces on target hardware

Tom Schultz
Expert 4160 points
Part Number: AM62P5
Other Parts Discussed in Thread: AM62P, SK-AM62P-LP, , SYSCONFIG

Tool/software:

Team,

Customer has received initial prototypes of one of their AM62P5x boards and wants to validate the operation of certain AM62P5x peripherals as they are not seeing the device load/boot.  This is a board we already performed a full schematic review for by Sreenivasa, so feeling confident about the design.  Please let me know your thoughts.

1. Customer wants to know if there is basic software code that can be used to validate the hardware interfaces (e.g., LPDDR4, FLASH, Ethernet, SD card) on their custom board, to ensure it is ready for software development.


2. They mention that during initial inspection, the voltage level from the PMIC was correct, but that the AM62P chip remains "blank".  They are seeking clarification on what this means and how to troubleshoot the issue.  I did send them the board bring up FAQ from Sreenivasa as a first step.  


3. They want to know if there is a library (or code) available to verify the working operation of the interfaces (LPDDR4, FLASH, Ethernet, SD card) on their custom board, similar to our SK-AM62P-LP EVM. What do we use for validating those interfaces on the TI EVM?  Can it be reused on a target board as is?

Thanks for your support.

    Hi Tom,

    Have you initialized the EVM with the SBL binaries?

    Please refer EVM_FLASH_SOC_INIT for details. 

    Regards,

     Hi Tushar,

    Customer respons:

    I am encountering an issue while booting a custom board (RDU120) using the same image that works successfully on the TI EVM.

    The image boots correctly on the EVM but fails on the RDU120 with the above error.

    This suggests a potential compatibility or hardware-specific configuration issue?

     

    We try to RESET using the button, but the same error messages appear.

     

    Could you please help us understand:

    1. Whether SYSFW version 11.0.7 is fully compatible with U-Boot SPL 2025.01?
    2. What could cause the frequency handshake timeout on a custom board?
    3. Any recommended debug steps or logs we should capture?

     

    Please let me know if you need additional logs or hardware details.

    Thanks,

    Tom

    Hello Tom

    This question was reassigned to me. At a high level we do not offer any board diagnostic package etc for customer board bring up. 

    Customers typically will leverage leverage our SDK and EVM as a baseline for reference software to manage their board port.  As you can imagine everyone's DDR , flash memory will be different , so it is important for them to understand how they can make adjustments for their board, if the components are different than our EVM

    First order would be to check if flash and DDR are working properly.  For DDR customers typically using Linux memtester etc.  They may want to see if they can use UART or any other mode to first ensure that DDR is working fine and/or ensure flash is working right. 

    If they are not seeing any signs of booting then they likely have something wrong in hardware or boot mode configuration. 

    I recommend that they post their observations on this E2E. I am happy to move this to external E2E , if it helps. 

    Regards

    Mukul

    Thanks Mukul.  I will provide them the feedback.  Feel free to move this to the external E2E, this was not an option when I first posted it though because the 'AM62P5' was selected.  Maybe since it's not released to production there is something preventing it from being on the public forum?  Perhaps there is a workaround for this limitation.

    Thanks,

    Tom

    Hi Mukul,

    Any luck being able to move this to the public forum?  In the meantime, customer would like to understand the error below.  What is taking place during the ‘frequency handshake’ and what needs to take place to get past this?

    U-Boot SPL 2024.04-ti-g29d0c23d67ee (Nov 29 2024 - 11:41:54 +0000)

    Timeout during frequency handshake
    ### ERROR ### Please RESET the board ###

    Thanks,

    Hi Tom,

    Tom Schultz said:
    Timeout during frequency handshake

    The error is from k3_lpddr4_freq_update() which is called by R5-SPL as listed below
    https://git.ti.com/cgit/ti-u-boot/ti-u-boot/tree/drivers/ram/k3-ddrss/k3-ddrss.c?h=11.01.06#n293
    DDR config is one of the initial HW initializations handled in R5-SPL.
    Have we updated the DDR config in the DDR DT node consumed by R5-SPL to match the DDR memory on the customer board?
    Best,

    Thanks Hong.  I've sent to the customer and will provide feedback.  In the meantime, the customer just provided the below boot log.  Does this reconfirm your suspicion about the DDR config for their DDR memory?

    Hi Tom,
    The error message <Timeout during frequency handshake> was not in the new boot log any more. It looks like DDR configuration is ok from the new boot log.
    Was the new boot log captured on TI reference board or the customer board?
    Best,

    Hi Hong,

    It was captured on the customer's board.  Any other ideas for what's going on?

    Hi Tom,
    I'm not able to spot any obvious error from the new log file. Is the new log a complete boot log?

    Hong, Team;

    They’ve gotten past the freq handshaking, but the question on why the board stops loading still hasn’t been fully determined/answered. Any help would be appreciated. I have also attached the latest full log capture, let me know if you need more. ?

    TY,

    Chris

    Hi Chris,
    It looks like kernel started bootup, and lock up somehow...
    Let me loop in my colleague to follow-up the kernel boot issue.
    Best,

    Hi Chris,

    Thanks for the email. The file you provided is about the DDR config in U-Boot. I will pass it to our DDR expert later for review if needed.

    Can you please provide the kernel board devicetree file?

    The corresponding file for the AM62P SK EVM is arch/arm64/boot/dts/ti/k3-am62p5-sk.dts in kernel source code.

    Per customer, they directly used TI SDK 10.01.10.04 and only replaced the DDR configuration. I don't think the kernel and U-Boot device trees (DTS) were modified.  Attached k3-am62p5-sk.dts https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/k3_2D00_am62p5_2D00_sk.dts

    Hi Chris,

    Thanks for the dts file. The customer did modified the kernel devicetree in the sdcard config section, though it won't be related to the current kernel boot issue.

    I am suspecting the problem is in the DDR config. I am discussing the DDR config data you sent to me yesterday with our DDR expert, and will update here.

    Thank you Bin, based on what you summarize, I can agree with that logic.

    Customer did provide the additional log file today, for reference.

    Please do let us know what you can further identify.

    TY,

    Hi Chris,

    Thanks for the update.

    Before we heard back from our DDR expert, can you please ask the customer to add 'mem=2G' to the kernel boot parameter (in U-Boot bootargs) to see if it makes any difference in kernel boot?

    One way to add this is to add the following line to the file uEnv.txt in the sdcard boot partition where all the U-Boot binaries are located.

    optargs=mem=2G

    Hi Bin,

    As per our Suggestions, they have modified mem=2G & mem=1G, and while there is an improvement, the problem message persists.

    Kindly review the attached files and share your feedback.

    TY,

    CY

    Hi Chris,

    Thanks for running the test.

    With less memory (1GB or 2GB) exposed to kernel, now kernel boot can pass the previous failure point. The problem is likely DDR related. I am routing your query to our DDR expert for comments.

    Thank you, Bin, agreed.

    We'll stay tuned for more.

    Chris is this related to the email? Or is this some other customer issue?  I think it would be good to get a DDR register dump from their board.  They can add a patch as described here: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1358039/faq-board-bring-up-tips-for-sitara-devices-am64x-am243x-am62x-am62l-am62ax-am62d-q1-am62px#:~:text=Getting%20DDR%20register%20dump%20after%20initialization

    Hi James,

    From customer (yes this is related to the email, same customer issue we suspect)...and I agree with your register dump suggestion, SO...

    "

    Added DDR register dump in our board.

    Kindly review the attached files and share your feedback.

    "

    Anything out of the ordinary here?

    TY,

    Hi Chris, both regdump show no issues with training.  It appears from both that training is completing and resulting values look reasonable.

    Have they even been able to boot successfully and run memtester?  I thought from the email they did run memtester, but i could be mixing up issues.  

    If they can't get to kernel prompt, they can add code to start running memtester out of the R5.  Use the link i provided above, and scroll down a bit and you will see instructions to add another patch to do this.

    Furthermore, they should probably look into another tool we provide https://www.ti.com/tool/download/DDR-MARGIN-FW which is a virtual eye tool to help determine if there are any marginality issues with the data bus.

    Maybe with memtester and/or the margin tool, we can help narrow down what the real cause of the failures are.

    FYI, i deleted the post, but kept the data from it.

    Regards,

    James

    James, Bin & Team ---

    Just circling back on this one if I may please.

    Any additional input is welcomed and appreciated.

    Thank you,

    Chris,i'm a little confused by the logs. 

    Memtester is supposed to run infinitely, but it appears to run into the Walking Zeroes test and then reset, and then hang.  Is this what is happening?

    Also, what is the difference between the 2 files you posted?  They look the same.

    Regards,

    James

    TI Team,

    The email exchanges have been a little bit inconvenient towards making real progress, so we are next proposing a call between TI and the customer to help resolve this in a more timely manner.

    Stay tuned for more.  If you gents can at least keep this in mind for a potential calendar invite, that'd be great.

    TY,
    Chris

    Team,

    Latest from customer today 8/18:

    On the memtester issue, [we] found that the MCU_ERRORn, a 1.8 volt signal was being pulled up to 3.3 volts and fed to the PMIC. [We] cut the MCU_ERRORn signal from the processor for now and that let us run without the memtester hang. [We] now both have MRIC-RP boards with the modifications.

     We are getting further.

     We can now run U-Boot for as long as we care to and it seems stable. We still hang when we try to boot Linux. See attached log. We hang at the last line:

    sched_clock: 58 bits at 200MHz, resolution 5ns, wraps every 4398046511102ns

    We have traced this into the point where we call to enable the GIC interrupts. At the point where we leave U-Boot, the GIC interrupt status looks good. The PMIC has errors on it, but we think we should be able to continue. W’ve a;sp tried all sort of things to try to convince the Linux kernel not to use timer interrupts, but nothing has helped. There’s a number of things we need to study more about.

     Friday and today, [we] were adding in some of the missing device tree items for the clocks, but so far nothing moved us forward. We found some web indications that it may be a clock domain problem. We continue to look at the differences in the device trees between the AM62P-LP eval board and the MRIC-RP hardware. We can dump both through U-Boot, so we get a look at what U-Boot thinks its really running for a device tree.

     We were thinking we should be trying to get Code Composer Studio or OpenOCD up and going on the CPU JTAG interface.

     We’d also like to get a TI SysConfig configuration file for our board. We think we could generate one, it would be time consuming. Steve Crump said he would look into it.

     We’ve been going back and forth between the running AM62P-LP evaluation board and the MRIC-RP and doing things like dumping the device tree’s between the two and adding in the support for things we need. We also even started by removing a good number of entries to simplify a starting point.

     Another thing we have been talking about is getting the AM62P-LP and the MRIC-RP on the same SDK version so we can better compare behaviors.

     [to TI] What additional information would you like?  And also do you have any guesses what we should be looking at? This is our MAIN focus for at least the short term, so anything you think we should chase would be great.

    TY,

    Chris

     

    It would be great to setup a call to talk about this.

    Chris, sounds like good progress.  I just want to make sure DDR is stable, because otherwise they will be chasing ghosts.  Have they verified that the patched memtester runs successfully?  Ideally across several boards?

    James

    Thank you, James.  I agree.  And tonight, customer shared "Only one board so far that I know of. We initially only had one board. We have two now and they are two different boards, so we will run the memtest on those boards." asap.  More to follow, thanks again, Chris.

    Team,

    Summary of our understanding today: 

    • They can boot to U-boot, clock timer interrupts hang the kernel in Linux (yesterday)
    • Latest memtester tests OK for the 32KB memory definition (today)
    • Pending memtester for larger GBytes memory definition (likely later today/tmrw)
    • DDR issue is prime culprit

    Thx,
    Chris

    TI__Guru* 87240 points

    Chris, at this point, i don't think it is DDR issue, but let's have them finish the memtester tests to confirm.  Once that is settled, we can discuss other possibilities.

    Regards,

    James

    James and Team,

    From customer tonight ---

    "

    I’ll let the team provide a full update, but [briefly] the team found a misconfiguration of the DDR config. The team was able to get a root prompt, but it’s still unstable (crashed after a few minutes). If they set the memory down to 512M, it seems (??) the kernel is stable (though not a useable configuration).

    The team is running an overnight test on the memory to see what might (?) be going on.

     That said, seems that the team is narrowing the issue, but we will setup a sync up call for tomorrow with this team.  

    "

    Scheduled 11am EDT / 10am CDT which I will move another mtg to make it work.  James you look free also.

    THANK YOU

    -Chris

    Ok, as mentioned on the call

    -perform full suite of memtester tests on a 128MB or 256MB buffer size.  Preferrable overnight on a few boards.  Further robustness can be test while doing memtester tests across temp (ie, boot at cold and run memtester as you warm the device to other extreme, and vise-versa)

    -use margin tool as mentioned on call: https://www.ti.com/tool/download/DDR-MARGIN-FW

    Initially the custom board boot gets stuck at the line above, which is in the very early stage of the kernel boot process. Can you please ask the customer what exact change they did to pass this point in boot?

    Hi Bin,

    We coincidentally met with the engineers today, in person, and actually progress is being made on a near daily basis.  They are past the main boot issues that prevented them from obtaining a Linux boot prompt.  They are now mainly focused on linux devicetree and continuing with app development beyond boot.  If and when I get the chance, I will try to ask your question.  I assume you are curious from a TI standpoint, since from their customer standpoint they are past this point now.

    Thank you,
    Chris

    Yes I want to know the root cause of the problem. I have been support Linux base port for years, but this is the second time that I see this issue report but don't know the root cause. (In the first report, the customer resolved the problem within a couple days but doesn't know what exact change solved it...)

  • 0 in reply to Bin Liu
    TI__Genius 15955 points

    Hi Bin,

    Understood.

    The answer here is this:

    Their main issue is that they had inadvertently configured the kernel to use more memory than they actually had on-board. This was the 8GB vs 8Gb issue Slight smile  --- once that was resolved the board booted as expected.

    Not sure if your other (first instance) customer has a similar issue or not but this was the main culprit for this above boot issue.

    TY,

    Chris
