Problem with TI TUSB8041IRGC USB3 Hub reset/detection in Linux

We encountered an issue with the TI TUSB8041IRGC USB3 Hub earlier in the year with not being able to detect the Hub in Linux on a regular basis. After analysing the reset pulse applied to GRST pin 50 of the Hub, we decided to lengthen the reset signal. This drastically reduced the likelihood of the USB3 Hub failing to be detected in Linux. However after a few months of trialing the long reset signal, we are still occasionally seeing the TUSB8041IRGC Hub not being detected in Linux. The ratio is significantly lower but can still occur in 1 out 20 times the board is power cycled.

The schematic for the TI TUSB8041IRGC Hub is attached. Nearly all Hub connections are on this page.

The images attached show oscilloscope captures of the GRST pin and the power supplies VDD (1.1V) and VDD33 (3.3V). Note the GRST pin has been held for 5 seconds after both power supplies are stabilised.

One second time base

10ms time base

Two Linux boot up logs are attached. One shows the Hub being detected in Linux and the other shows the issue where the Hub is not being detected.

The file names are:

USB3-Hub-not-found.txt
USB3 Hub-Detected.txt

In the former file we can see the failure (i.e. no USB3 Hub is found). When the lsusb command is typed in, only the root hub device which is a Linux virtual hub is displayed, but no real devices are found. In the latter file (USB3 Hub-Detected.txt), we can see the USB3 hub has been found.

See the comparison image snap shot attached.

Could you kindly guide us and shed some light on what could cause the Hub to not be detected in Linux like this? We have been using the TI TUSB8041IRGC USB3 Hub since 2017 in our prototypes. We have had over 40 prototypes made and recently had 300 pilot production boards made and are about to start shipping some production units to our first customers. Hence we would really like to get to the bottom of this problem.

did you try 3.3v up before 1.1v?

0 Malik Barton57 over 6 years ago in reply to Brian Zhou

TI__Guru 64326 points

Hi,

Please refer to section 7.6 Timing Requirements, Power-Up and see the figure in that section for the recommended power-up procedure. Powering VDD1.1 before VDD3.3 can cause the state machine to get stuck in a bad state.

0 Nikhil Rao82 over 6 years ago in reply to Malik Barton57

Hi Brian, Malik,

On the very first design we powered up 3.3V first and then later powered up 1.1V. However on the 2nd prototype run onwards this was changed to power up 1.1V first and then 3.3V. The sequence change (i.e. powering 1.1V first and then 3.3V), reduced inrush current into the Hub.

I believe we have the flexibility to change the power sequence, which is carried out by a CPLD. We can try this late next week and report back, once a colleague of mine has come back from leave.

Looking at page 11 from the TUSB8041 datasheet, we assumed that there is no required power sequence for the Hub and either power supply could be powered up first.

Section 7.6 is written in an open ended way and is slightly ambiguous. From reading notes (1) and (2), one would assume that an active reset is not required if VDD11 (1.1V) is powered up before the VDD33 (3.3V).

But we can try switching the power sequence and report back if it improves things. It will take us some time to do this because currently the failure rate (i.e. of Hub not being detected in Linux) is quite low: about 1 in 20 reboots (full board power cycle). So we have to run 100s of restart trails to see how the power sequence change performs.

Meanwhile if you have any other comments please let us know. Kindly keep the thread open, till I report back.

Thanks,

Nikhil

any new test result?

0 Nikhil Rao82 over 5 years ago in reply to Brian Zhou

Prodigy 220 points

Hi Brian,

Sorry for the delayed response. I modified our CPLD code to change the power sequence for the TI TUSB8041IRGC USB3 Hub.

Now the 3.3V supply starts up before the 1.1V supply. See below.

There is around 6ms between enabling of the 3.3V regulator and the 1.1V regulator, but due to the soft start characteristics of the 3.3V regulator it eats into this 6ms delay. I hope this is not an issue. Please let me know if further delay is required between the two regulators?

My colleague is back this week. I will get him to test the modified board (which has the above sequence) with the U-Boot and Linux software build and will report back in the next two days.

Kind Regards,

Nikhil

0 Nikhil Rao82 over 5 years ago in reply to Brian Zhou

Hi Brian,

My colleague tested the TI TUSB8041IRGC USB3 Hub in U-Boot and Linux over multiple trials earlier today, after updating his board with the new power on sequence (i.e. 3.3V turns on first, then 1.1V).

Out of 20 trials (each trial being a full power on, system boot of U-Boot + Linux and then power off), there was 1 failure (5^th reboot) found. During this 5^th trial the TUSB8041IRGC USB3 Hub was not detected in Linux.

I'm thinking of increasing the delay between the 3.3V turn on and 1.1V regulator being enabled. I'll make the modifications and get my colleague to retest the TUSB8041IRGC Hub tomorrow. Meanwhile if you have any other suggestions do let us know.

Currently the 1 out of 20 trials failure (to detect the USB3 Hub) rate is about the same rate we were seeing earlier with the old power sequence (when 1.1V was switched on first followed by 3.3V). Please note the reset window time was unchanged in the new trials carried out and a very long 5 second reset was provided on pin 50 GRST (i.e. the line was held logic low or 0V for over 5 seconds after the power supplies stabilised and then it was driven to a logic high or 3.3V).

Kind Regards,

Nikhil

Okay yes we can try this also and report back. I'll get R91 disconnected from the 5V rail and instead connect it up to the VBUS output 1 from the TPS2561DRCT power switch.

0 Nikhil Rao82 over 5 years ago in reply to Brian Zhou

Hi Brian,

Sorry for the delayed response. We encountered some issues with the changed power up-sequence (now 10 stages for this board). It is fixed now. This is the sequence below just for the TI TUSB8041IRGC Hub. Compared to our previous attempt we managed to increase the delay between the 3.3V regulator and 1.1V regulator by making some changes to our CPLD code.

My SW Engineering colleague ran another set of trials (20 total) earlier today. In the first 10 he found two failures (i.e. not being able to detect the Hub in Linux). In the second set of 10 trials run slightly later he came across 1 failure. So in total the Hub could not be detected in Linux 3 times out of 20 power cycles (off - on - off).

In summary we don't see any improvement by altering the power sequence. With the old sequence (1.1V starting up first then 3.3V), the failure rate was about the same.

We will try your other suggestion (disconnect R91 from the 5V rail and instead connect it up to the VBUS output 1 from the TPS2561DRCT power switch) hopefully tomorrow and report back.

Kind Regards,

Nikhil

0 Nikhil Rao82 over 5 years ago in reply to Nikhil Rao82

Prodigy 220 points

Hi Brian,

We tried your second suggestion of disconnecting R91 from the 5V rail and instead connecting it up to the VBUS output 1 from the TPS2561DRCT power switch by soldering a link wire.

See the attachments for a visual representation of what was attempted.

Unfortunately after this change the TUSB8041IRGC USB3 Hub never worked in Linux. We double checked the hardware changes yesterday and the modifications were done as per your suggestion. However the Hub could never be detected in Linux.

So in summary what we have found is as follows:

Original Power Sequence (1.1V Regulator powers up first, then 3.3V Regulator) - Around 1 to 3 failures in 30 attempts. Note 100's of attempts have been done by our Production Department and they are still seeing failure to detect the Hub in Linux every now and then. They have to restart the board when such a failure occurs.
TI suggestion of changing power sequence (3.3V Regulator powers up first and then 1.1V Regulator) - Up to 3 failures in 20 attempts. Seems as bad if not worse than our original power sequence.
TI suggestion of connecting R91 to VBUS, instead of 5V rail - 100% failure so far. Hub doesn't work in Linux as it can't be detected at all.

In light of the above findings we have reverted back to our original implementation of the CPLD code to power on the 1.1V rail followed by the 3.3V rail.

Are there any other suggestions you can provide us? If not could you perhaps get in touch with the design team for this TUSB8041IRGC Hub and explain our problem to them, along with our attempts to fix it. Our new product is being shipped to our launch customers this month and our product is required to be a very high reliability platform. In the field the product is rarely rebooted/power cycled (only firmware upgrade). But we don't want our customers to be in a situation where they have to reset the board to get this USB3 Hub working. Hence we really need TI's assistance to understand this problem and fix it. Note when the Hub has been detected in Linux it runs reliably and large amounts of data have been transferred over the USB3 Super Speed link without any issues.

Kind Regards,

Nikhil

TI__Guru 64326 points

Hi Nikhil,

I believe when implementing the second fix VBUS_DET of TUSB8041 was connected to the VBUS voltage from one of the downstream ports of TUSB8041, is this correct? Since TUSB8041 is disabled it will not be driving the EN pin of TPS2561. TPS2561 may be "off" in this case therefore DN1_VBUS and VBUS_DET will never go "high". If VBUS_DET is not driven high TUSB8041 will not "know" to enumerate and the USB Hub will not be seen in Linux. Typically, you would have the upstream connector VBUS voltage be connected to this pin through the recommended resistor divider. The upstream connection has no exposed port, correct (upstream USB to USB Hub is completely internal)? For my information, when does 5V become stable in relation to 1.1V and 3.3V with both original CPLD code and the modified version?

I believe that the first workaround may still work. In this case, are you able to connect GRST to a signal that will delayed at least 3 ms after VDD 1.1V is stable? Per your last figure 1.1V rail becomes stable at the same time GRST is de-asserted ("goes 'high").

0 Nikhil Rao82 over 5 years ago in reply to Malik Barton57

Prodigy 220 points

Hi Malik,

Yes VBUS_DET (pin 48) of the TUSB8041IRGC Hub was connected to a downstream device in the second attempt. Your explanation makes sense as to why it never works in Linux after this change. The Hub is permanently integrated into our board and the upstream port is the NXP LS1021A CPU. The upstream VBUS is the 5V Power Regulator on the board and currently the 5V Rail is enabled at a much later time period compared with the 1.1V and 3.3V rails. I am not sure when the 5V rail is enabled compared with the GRST signal being de-asserted. I'll find out and get back to you.

The 5V rail is not currently controlled by the CPLD, but we can try to enable it at the same time as the 1.1V or 3.3V rails by making a board change (solder a wire link).

We still have a very long 5 second delay on the GRST signal (pin 50) after both 3.3V and 1.1V are enabled. The GRST is being driven low and after 5 seconds of the power rails stabilising it is de-asserted to a high state. The oscilloscope image provided on Oct 9, 2019 5:52 PM actually shows the enable signal for the 1.1V regulator and not GRST. We had some issues while changing the power sequence and my colleague working on this was capturing additional signals to debug the problem. But I'll get him to capture the GRST again compared with the 3.3V and 1.1V start-up. Unfortunately both of my colleagues working on this issue have been occupied this week with a conference, but I'll try and get back to you by Friday or early next week at the latest.

Kind Regards,

Nikhil

0 Brian Zhou over 5 years ago in reply to Nikhil Rao82

TI__Guru*** 146195 points

Nikhil:

5V for Vbus_det should be on after GRST goes high. Also It need 3ms for GRST at low after 1.1v/3.3v stable. 5 second may be too long.

Regards,

Brian

0 Nikhil Rao82 over 5 years ago in reply to Brian Zhou

Prodigy 220 points

Hi Brian,

The original reset assertion time for GRST was around 10 to 20ms. But we had frequent failure of the TUSB8041IRGC Hub on power-up (around 40%). I.e. it was very frequently not being detected in Linux. After drastically increasing the reset assertion time to 5 seconds, the failure rate of the Hub dropped considerably to about 1->2 times out of 30 trials. But even such low occurrence of failure will cause us issues and won't be acceptable to our testing team.

My colleague investigated the 5V regulator turn-on. Please see the two plots below which show when the 5V rail powers up in relation to the other power rails (i.e. 3.3V and 1.1V) and GRST signal.

The 5V rail is connected to USB_VBUS (pin 48 on the TUSB8041IRGC Hub) via a voltage divider network (R91/R79) Please note my colleague reverted back to the orignal CPLD image from a few months back, because the altered sequence (3.3V powering up first, then followed by 1.1V), gave no improvement.

The 5V rail's enable/disable signal is configurable in software. I'll request my SW Engineering colleague to create a modified firmware to delay the 5V rail's power on, till after the Hub comes out of reset. I'll report back to you on this soon.

Kind Regards,

Nikhil

Hi Brian,

I have some slight good news.

Towards the end of last week my colleague prepared a modified software build which delayed the 5V regulator start-up (sorry don't have the oscilloscope capture, but the 5V rail was enabled several seconds after GRST de-assertion). The 5V rail is connected to USB_VBUS (pin 48) on the TUSB8041IRGC Hub and basically it's power-on was delayed till after the Hub came out of reset (i.e. well after the deassertion of the GRST signal on pin 50).

A total of 40 trials were conducted on two different boards (20 trials on each board) using the modified software build. All trails were successful and the TUSB8041IRGC USB3 Hub could be detected every single time in Linux on both of the boards.

I'm trying to get some other resources within the company to conduct further trials on this, because as you know with our previous attempts the failure rate was quite low (1-3 failed to detect in Linux out of every 20 to 30 reboots) and we want to be sure this change (delaying 5V turn on after GRST de-assertion) is definitively working.

Thank you to Malik and you for your suggestion about investigating the 5V rail and its relationship with the other power rails and reset signal.

I'll update you hopefully in a few days, once we perform further trails on other hardware boards.

Kind Regards,

Hi Brian, Malik,

We ran 106 trails on another board on Monday and 585 trails yesterday overnight. Each trial involves a full power up, boot up of the board (U-Boot + Linux) and power off.

All trails were successful and the USB3 Hub could be detected in Linux every single time. Delaying the 5V regulator startup till after GRST has solved this problem. Thank you for your help. In due course we will try a shorter reset signal for GRST and repeat the trails.

Kind Regards,

Nikhil
