AM5728: Overheating and chip damage with SDK 06.01.00.08 but not 02.01.00.07

Hi Chris,

This is indeed a strange problem - can you share the full part number for your PMIC?  I will look up the power sequence set by the OTP of your PMIC revision.

Is this the thread you found on this topic: https://e2e.ti.com/support/processors/f/791/t/719849?AM5728-Power-sequencing-violation-causes-overheating

Can you confirm the IO supply rails are up before reset is released?

Regards,
Mike

The PMIC part we order is TPS6590378ZWSR or TPS6590378ZWST.

The markings on the chip itself (on one of the failing boards) are

TPS659037 OTP 8A 1.3 66AR4VW G2 G1

Yes, the "Power sequencing violation causes overheating" is the thread I found which appears to describe the strange thermal behavior I'm seeing.

At the moment I'm working at home and my office here lacks a quad-trace scope, so I need to go to my bench at work for that or get someone else to do it. Will post as soon as I have info.

Reviewing the u-boot code board-related differences between the 2 sdk versions, I see that there was the following addition to the PMIC late init code:

commit 385d3632ba63f9a60047fa9f4f0a7d9629bc0613
Author: Keerthy <j-keerthy@ti.com>
Date: Wed Nov 30 15:02:53 2016 +0530

am57xx: Set tps659038 PMIC GPIO7 pad mux value to POWERHOLD

The GPIO7 pad mux should be programmed to POWERHOLD value
as per board design. In cases where the PMIC is shut off the
mux is set to GPIO7 mode. So during initialization to be on the
safer side set the mode to POWERHOLD.

Our existing older u-boot code does not do this (it only sets DEV_CTRL.DEV_ON bit to 1). Is the above commit relevant to the problem at hand? The comment refers to a different PMIC part number than we are using.

---Chris

Thanks Chris.

I saw that too, and will be following up with the PMIC team to understand if this is somehow problematic with your OTP version.

Regarding your board layout, did you model the design after any of our EVMs?  This would help the PMIC team understand if there are any potential conflicts.

Regards,
Mike

Yes, our board design is originally modeled on the the AM5728 EVM/BeagleX15, but it is about 30% larger (there is an FPGA and a bunch of A/V related parts/IO etc.) and with a somewhat different peripheral layout.

---Chris

Also FYI the referenced PMIC GPIO_7 line is grounded (via 10K resistor) on our board - so it's not clear how any reprogramming at boot time would have an effect.

---Chris

Here is some detailed analysis of what we're seeing with this. Pretty clearly the new firmware is inducing a power sequencing issue, because all the rails come up for 5ms or so except for the 3v3 rail which is only partially up; then they drop and come back again after ~20ms. Clearly wrong, and this only happens when booting to the new SDK.

Attached are traces for both the good/old firmware and the bad/new firmware on the same board.

Old firmware is u-boot and kernel from 02.00.01.07 SDK, new is from 06.01.00.08 SDK kernel with identical (old) u-boot.

Please advise.

Here is the good power-on, using old firmware:

And here is the bad one, using same board, new firmware:

The issue is due to a reset of the PMIC which is forced by the Linux driver after the kernel loads, due to the default new feature 'ti,palmas-override-powerhold' being present in the DTS for the TPS659037 driver and on our board PMIC GPIO7 is always held low; this triggers an immediate PMIC reset when the driver loads with the override feature enabled. Removing 'ti,palmas-override-powerhold' from the device tree allows the system to start normally with no changes to the older u-boot.

Hi Chris,

Thank you for posting your debugging efforts. Does this solve your issue, or are you looking for additional clarification?

Regards,
Mike

No, the issue is not yet resolved. Here's an update:

1. By disabling the override-powerhold in DT we get one clean boot into the new SDK; subsequent power cycles into old or new firmware after that still go into thermal overrun (board draws about 18W when this occurs, normal draw is ~5-10W).
2. Using the RESET button when AM5728 chip is in thermal overrun clears the condition and the resulting reboot is normal.
3. The overcurrent/overtemp condition occurs again at the next power cycle regardless of firmware booted.
4. After a sufficient rest period (overnight) an undamaged board responds normally to old firmware again, and allows one normal boot to the new firmware, but then exhibits the same failure mode as above.

After testing with a back-ported u-boot PMIC-related board file change mentioned earlier in this thread, we found it had no effect.

Currently we are looking at the I2C traffic on the PMIC for both firmware revisions for analysis, but have no way to know if it will provide useful info.

Thus we still cannot use/deploy the new SDK, and are looking for any help TI is willing to provide.

Hi Chris,

Thank you for sharing your observations.

When you're power-cycling, is the mains supply removed, and the PMIC is doing a full cold-boot?

Do you have any traces showing the power sequencing on subsequent power-cycles, or is the trace above showing the "bad" behavior representative of this?

And can I also assume if you start testing with a cold board, using the old SDK 2.x based firmware, it will always behave as normal between power cycles?

My suspicion is the PMIC registers are getting programmed, and when we power down, the PMIC is going into suspend state, and those values are retained for subsequent boots.  Otherwise I'm having a tough time wrapping my head around how the board could behave differently between cold boots.

Are you able to dump the PMIC registers from u-boot after each power cycle, and compare old vs new firmware?  If you need help with this, I could probably whip something up for you.

Regards,
Mike

> When you're power-cycling, is the mains supply removed, and the PMIC is doing a full cold-boot?

Yes. For my testing I simply unplug the 5V DC input to the board and let it settle for 15sec or so before re-connecting it. How could I verify and/or ensure that the PMIC performs a "full cold boot"? Shouldn't that happen by default when power is lost/re-applied? I believe we are correctly configured for the "powerhold low" cold start scenario in the PMIC docs; we do not have an onboard power switch - the board is designed to be always-on, although we do have a Reset button.

> Do you have any traces showing the power sequencing on subsequent power-cycles, or is the trace above showing the "bad" behavior representative of this?

The latter; 'bad' trace above shows what is happening. 

> And can I also assume if you start testing with a cold board, using the old SDK 2.x based firmware, it will always behave as normal between power cycles?

Yes. We have thousands of boards in the field with no issues using the old firmware and we never saw anything like this issue before. Only using the new firmware causes it.

> My suspicion is the PMIC registers are getting programmed, and when we power down, the PMIC is going into suspend state, and those values are retained for subsequent boots.  Otherwise I'm having a tough time wrapping my head around how the board could behave differently between cold boots.

Agreed, sounds likely.

> Are you able to dump the PMIC registers from u-boot after each power cycle, and compare old vs new firmware?  If you need help with this, I could probably whip something up for you.

Yes, I can do that using the u-boot i2c driver. Of course it will be a pretty big dump with ~5 pages of regs. Meanwhile I will also snag the I2C traffic directly to see what's going on; this should provide similarly useful info presuming that the PMIC registers are being programmed differently by the new firmware.

Chris,

Thanks again for the additional information.

To me it does sound like you're doing a true cold boot, but not sure if the PMIC register values are still being retained by residual capacitor charge.

Regarding the PMIC registers, these can be dumped with a simple u-boot command sequence, i.e., no need to modify the I2C driver itself.  Let me put something together for you.  There will be a lot of values, but the goal would be to run a diff on the output and look at the deltas.  I am building the old SDK here, and can run the same test on an EVM to compare our results.

When you boot up in the "bad" state, how much time do you have before the board overheats and is no longer usable?  I'd like to suggest a few tests from Linux, but if we only have a few seconds, might need to restrict testing to just u-boot for now (assuming we do not also overheat in u-boot).  Primarily, would like to see the reported values for the system clocks and voltages (i.e., "omapconf show opp").

If you could probe any of the rails that use AVS, that would also be helpful (MPU, DSP, GPU, etc).  Want to make sure these supplies are at the same level in the old vs new firmware.

Regards,
Mike

Mike,

If you can provide a u-boot script to dump the PMIC regs, that would be great. I experimented with the i2c u-boot command but couldn't get it to do anything useful - no doubt I was missing a bit of magic there somewhere. The docs, shall we say, are pretty thin.

Regarding the old SDK, I see that I was dyslexic when entering the version number: it's actually 02.00.01.07, but you probably figured that out already.

Amount of time before runaway die temp hits 90C is less than a minute, a bit more with active cooling, but does allow for some Linux interaction. The network is totally dead, but other subsystems including console appear to work during this time, so I'll post the omapconf results here later today, as well as more i2c info.

Regards,

---Chris

Hi Chris,

Thanks for your patience - needed to figure out just how the register addressing scheme worked on the device.

The script is pretty simple.  You can simply paste these commands into your u-boot terminal:

i2c dev 0
i2c md 58 0.1 100
i2c md 59 0.1 100
i2c md 5a 0.1 100
i2c md 5b 0.1 100

Your output will look something like this:

=> i2c dev 0
Setting bus to 0
=> i2c md 58 0.1 100

If the output is the same in both "good" and "bad" cases at the u-boot stage, we will need to do the same in Linux to get a better handle on what Linux is actually changing.  I'll get started on creating those commands now, and will post shortly now that I understand the addressing scheme.  BTW, it looks like the OTP section at chip address 0x5B is not readable, so you could omit that if it is all zero's for you too.  Also, depending on how you've implemented the device, you may need to subtract 0x10 from the chip addresses (48, 49, 4a, 4b).

Chris,

Here is the command sequence for Linux:

i2cdump -f -y 0 0x58 && \
i2cdump -f -y 0 0x59 && \
i2cdump -f -y 0 0x5a && \
i2cdump -f -y 0 0x5b

And the output will look like this:

root@am57xx-evm:~# i2cdump -f -y 0 0x58 && \
> i2cdump -f -y 0 0x59 && \
> i2cdump -f -y 0 0x5a && \

Mike,

Here's what I've found so far with various additional tests and the commands you've supplied. Anything below labeled "bad" indicates that the board was in the high-current thermal runaway state when the dump was taken; "good" means normal operation.

0) Since we are using an identical u-boot for both the old and new SDK boots, the issue must be with something linux is doing (or possibly something u-boot is not doing, but we did test the only board-file PMIC related change and it had no effect.)

1) The difference in u-boot register dumps between good and bad states are two registers in the 59 bank, 0x210 and 215. These correspond to INT1_STATUS RPWRON and INT2_STATUS RESET_IN being asserted in the failing case:

> 0010: 08 c7 06 00 00 10 aa 00 00 00 00 fc 00 00 00 00    ................

2) The difference in linux register dumps between old/good and new/bad are in RTC time registers (expected) and INT1_STATUS PWRON (asserted in bad case) :

3) omapconf works fine when in the good state, fails completely in bad:

NAME

        omapconf - TI OMAP Configuration Diagnostic Tool

SYNOPSIS

        omapconf [--version] [--help] [--cpuinfo] [--buildinfo] [--import <file>] [--force <cpu>] [--norw] <command> [<args>]

        See 'omapconf --help' for more information.

4) In bad state, PMIC i2c is not visible from command line:

# i2cdump -f y 0 0x58 && i2cdump -f y 0 0x59 && i2cdump -f y 0 0x5a && i2cdump -f -y 0 0x5b

Error: I2C bus name doesn't match any bus present!

5) Using a bus probe on the PMIC I2C shows that the kernel write patterns for the PMIC are completely different between the old and new kernels. I have detailed, very large dumps of this if they would prove useful, I can post them at your request.

I've attached below the line all the data in the register comparisons shown above.

Thanks Chris.

There is something very strange happening if we cannot read I2C or omapconf is not working in the bad case.

Sorry to keep asking for more information - can you also post the full boot log (u-boot and kernel) in the good and bad case?  I am suspecting there are a bunch of driver errors when you boot up the second time and this might have some clues.  Specifically, I am wondering if the board/ device detection logic is working correctly.

Regards,
Mike

Mike,

You'll find the requested logs below.

Seems that whatever condition is causing the thermal runaway hoses the silicon in a lot of ways - the network port is completely dead in this case as well. Interestingly, I can see with the i2c hardware bus monitor that traffic is happening between the PMIC and processor here even though i2cdump won't work.

FYI we build the SDK filesystem to use sysvboot instead of systemd, and these logs include output from some of our own apps that are run during start up to initialize the FPGA etc.

Regards,

---Chris

Hi Chris,

I did a diff on your two kernel logs, and didn't really see anything alarming in the bad case.

Few follow-up questions:

1) is your reset button tied to the warm reset input on the PMIC?  On our EVM, we have a DNI resistor in this path, so the push-button reset will only reset the processor.  Wanted to confirm if your reset button is resetting both PMIC and processor, or just the processor.

2) it looks like when the PMIC reset occurs, REGEN1 does not go back to 0V, rather sits as some mid-supply value (looks like about 1v?).  On our EVM, this is supplying the main 12v to 3.3v buck.  If your board is implemented in the same way, does the 3v3 regulator get enabled by this runt pulse?  And if so, does it stay up while the other supplies are reset?

3) can you confirm the PMIC reset is occurring in Linux, or u-boot?  Looking at the time stamps, it is not clear if T0 begins at power-on, or if you're triggering on something else and the time scale should be considered relative.  I'm asking because the best action would probably be to modify the driver such that this reset does not occur, and need to understand if the Linux or u-boot driver needs the patch.

4) are there any other changes to the layout from the AM5728 EVM, especially related to power supply and reset to the processor?  If you happen to know which revision of the EVM your schematics were based on, that information might help as well, just in case we made some changes over time.

Regards,
Mike

Hi Mike,

In answer to your questions above:

1) The PMIC warm reset is not connected to the reset button. PMIC warm reset is driven only by the AM5728 reset out.

2) In our design REGEN1 drives the enable on a TPS22920 that switches the 3.3V rail to the majority of the board, including the AM5728. 1V is between the high and low thresholds of the enable so it may be on, off, or partially on.

3) I haven't probed for this explicitly at the signal level, but given the fact that u-boot is the same, and running the old SDK kernel does not cause the reset, I think it's safe to assume that the new SDK kernel is what initially causes it. However, also recall that once the failure mode has occurred, the same behavior happens even when booting to the old SDK again (without a long rest period) so something peculiar happens as a result of the first reset which persists the condition.

4) No EVM schematic was available from TI when we started this design. TI put us in contact with a designer at BeagleBoard who provided the schematic for the BeagleBoard-X15, dated May 2015. We later incorporated changes from the Rev A2b EVM schematic, dated October 2015.

Regards,

---Chris

Chris,

Thanks for answering all my questions!

Can you get a scope capture as you provided in the past the shows REGEN1 and the main 3V3 supply during the bad case?  If the 3V3 supply remains up during the PMIC reset, this is a problem and can be a cause for what you're experiencing.

The load switch data sheet lists the minimum VIH spec at 1.1V.  This is right on the edge based on your sequencing trace in the bad case.  REGEN1 should be push-pull by default, and not sure why this output does not get pulled down.

I will dig into the Linux PMIC driver, and see if we can provide a patch that will disable the PMIC reset.

There is also some concern that the processor may not be shutting down when die temp reaches 125C.  Do you have a way to measure the temperature (thermocouple, IR probe, etc)?  There is a notice in the errata (i827) that would be worth looking at:

i827 Thermal Alert Will Not Be Generated When Bandgap Is Configured in "Smart Idle" Mode
CRITICALITY Low

The MPU will not receive an interrupt request for thermal alert (MPU_IRQ_126) if the MPU bandgap cell is in idle mode. When the MPU bandgap cell is in idle state (CTRL_CORE_BANDGAP_MASK_1[31:30] SIDLEMODE=0x2), the MPU bandgap state machine can not send THERMAL_ALERT signal and MPU interrupt request, respectively.

GUIDELINES Do not idle the Control Module MPU Bandgap (keep CTRL_CORE_BANDGAP_MASK_1[31:30] SIDLEMODE=0x0)
REVISIONS IMPACTED SR 2.0, 1.1

Regards,
Mike

Mike,

We're working on the scope capture and should have that for you later today.

I have observed that auto thermal shutdown does occur right around 100C, however, I've tried to avoid allowing the die to get that hot. The temp monitoring I've done is just via /sys/class/thermal/... zone values and toasted fingers so far.

I was able to get a reasonable omapconf output for a subsequent "bad" run, see below.

More later,

Thanks Chris.

Can you also take a look at the output of "top" and see if there are any processes that are heavily loading the CPU in the overtemp case?

Regards,
Mike

Yes. I've done this many times and 'top' shows a nominal CPU load of <10%.

---Chris

Chris,

OK, that's interesting.  Can you try running 'cat /proc/interrupts' and see if there are any that are rapidly increasing?

If there is truly low CPU loading, then this is pointing more and more to a power sequencing issue causing the processor to come up in a bad state.

Regards,
Mike

Hi Chris,

Speaking with one of our Linux driver experts, he recommended the following as a test:

From the device tree file arch/arm/boot/dts/dra7-evm.dts, please remove regulators below:

      /* REGEN1 is unused */

                                regen2: regen2 {
                                        /* Needed for PMIC internal resources */
                                        regulator-name = "regen2";
                                        regulator-boot-on;
                                        regulator-always-on;
                                };

                                /* REGEN3 is unused */

                                sysen1: sysen1 {
                                        /* PMIC_REGEN_3V3 */
                                        regulator-name = "sysen1";
                                        regulator-boot-on;
                                        regulator-always-on;
                                };

                                sysen2: sysen2 {
                                        /* PMIC_REGEN_DDR */
                                        regulator-name = "sysen2";
                                        regulator-boot-on;
                                        regulator-always-on;
                                };
                        };

That leaves us with only the voltage regulators. Another thing that i want to check is to
remove the "ti,system-power-controller" property from tps659038 node.

That would mean any software poweroff call will not go all the way to the PMIC.

If there is still no change, I think the next thing to look at is what else could be changing with the new firmware.  What other components on the board are coming up when the PMIC is reset?  Could there be some other device that is inducing the behavior?

Hi MIke,

Well... the dra7-evm.dts file does not get used in our setup as we are based on the am57xx EVM using am57xx-beagle-x15 and related DTS files. These have only regen1 (do not define regen2) and do not define sysen1 either, so please confirm what should be removed for this test here.

I will however check removal of the ti,system-power-controller property from the PMIC node and let you know the results.

Regards,

---Chris

Hi Chris,

Sorry about that, you're right.  I blindly copied-and-pasted the response from another engineer and must not have explained the situation carefully enough.

Basically the goal is to try stripping out portions of the PMIC node to eliminate the possibility of the Linux driver potentially generating a reset.  I'm not actually seeing any specific functions in the PMIC driver itself that would be generating a reset, however, so must be coming from the OS, if that is indeed what is happening.

Have you by chance been able to verify if the 3V3 supply to the processor is getting powered, and staying up during the PMIC reset?

Regards,
Mike

Hi Mike,

Making the suggested DT changes does not appear to have any effect, however, I will have to try this on more boards before I can be sure it isn't just that the 2 I have here have been damaged by previous tests.

From our other tests so far it appears that the 3v3 line is not staying up during reset, but I'm not sure we got the test trace properly triggered - will advise when I have more confidence on this.

Meanwhile, can you please verify that the attached PMIC schematic section is correct for our situation (no power button, power applied will sequence all the rails correctly), and that the PMIC GPIO assignments have not changed since SDK 2.0.1.7?

Regards,

---Chris

Chris,

Apologies for the long dela while I was out of the office.

Your schematic is inline with the X15 and AM5728 GP EVM.

I've gone back to checking your register dumps to see if there was anything that I missed the first time.  If you have the I2C traffic you acquired previously, that might help.  Would be especially be interested in the sequence events leading up to the PMIC reset.

You also said your power cycling tests have been done by physically removing power - if that is correct, can you try doing a controlled shutdown from Linux ("poweroff" command)?

Regards,
Mike

Mike,

Good to hear from you again. We're having trouble making much progress on this on our own.

Linux poweroff command on our board does not actually turn off power (for reasons unknown, but I recall an errata in this area from board bringup way back when) yet if it did, we have no way to turn it on again (unit is always powered for our use case so we have no power button.) If I run 'poweroff' to the point where the 'System halted' message is printed and then do a physical power cycle, it still goes into runaway.

However, we do have the processor reset wired to a GPIO and hooked in to the 'reboot' command mechanism, which does work. That is, if the unit is in runaway, doing a proc reset fixes it (either programmatically or via the reset pushbutton.)

I do still have the I2C traces and will post them before end of day. What I don't have is an easy way to correlate the PMIC reset with the I2C because that test was done without the rail probes. If this would be helpful, we should have the resources to do it and get results mid-week - let me know.

Regards,

---Chris

Attached are CSV files of i2c captures from 4 scenarios:

good-old1.csv - startup with old firmware, no runaway. 

good-new1.csv - first startup with new firmware, no runaway, but subsequent starts of new or old FW will runaway

bad-new1.csv - re-power new FW after good-new1, runaway

bad-old1.csv - repower old FW after good-new1, runaway

We have also found that some apparently small percentage of boards are "immune" to this issue and never fail. We have also established that the failure occurs regardless of boot medium (eMMC vs. SD card) and filesystem type (RAMFS vs. eMMC or SD).

Jian,

Please post your response now, the thread is unlocked.

Chris, 

This thread were overlooked due to some team transitions. I apologize for the extended delays in response. could you confirm back the issue is still blocking your software upgrade, then I will review the power sequencing with the hardware team. 

thanks
