OMAP35x HSUSB Interoperability issue with SMSC USB3320 PHY

The errata is applicable only to SMSC USB3320 PHYs. TI internal team have verified NXP ISP1703 PHY and recommends the same to be used.

Ajay

Hi Ajay,

This behaviour of USB3320 is seen on OMAP host side only as per errata. Can this behaviour of USB3320 be a problem when this PHY is used with OMAP OTG port in a device only functionality?

Actually I am using USB3322 (which has same die as USB3320) with OMAP OTG port and it is configured for device only applications. I am facing a peculiar problem with some of my boards where I am not able to do peripheral booting through USB. Please refer to below thread for details:

http://e2e.ti.com/support/dsp/omap_applications_processors/f/447/t/51032.aspx

I was just wondering whether this behaviour of USB3322 can also affect peripheral booting through USB.

Regards,

Vinod

Vinod,

I am not aware of any such issue affecting OTG peripheral mode.

ajay

Has TI or ayone else used USB3320 with OMAP OTG port?

Ajay,

I realize this is a bit of an old thread, and I am sorry to dig it up, but since it has been a while, have any other PHYs been verified to work around this errata properly?

Bernie,

We are using the TI TUSB1210 in our design and the device is properly suspending and resuming.  I don't know what TI does to verify USB PHYs, but from my perspective the 1210 works.

Is there any update with regard to compatibility between the TI OMAP3530 and the SMSC USB3320?  The reason for my question is that there is a Beagle xM board with the USB3320 that works.  I have a board with the exact same part (USB3320C) that is is not working.  Right now I am thinking it is a kernel problem, but an having trouble seeing how the Beagle board xM source sets up the USB3320.

These are the lines from the log that make me think I have a "setup" problem:

<3>HS USB OTG: no transceiver configured
<3>musb_hdrc musb_hdrc: musb_init_controller failed with status -19
<6>

Wayne

Wayne,

The error seems to eb due to no transceiver configured. As you are using SMSC USB3320 PHY so you should enable NOP transceiver at Drivers->USb support-> go to th ebottom and select NOP

Pleas also make sure to disable TWL4030 transceiver.

Ajay

OK.  I have the NOP enabled and the TWL4030 transceiver disabled in the kernel.  I am getting a kernel panic.  I fixed on item in the kernel where musb_free() was attempting to use a null pointer and now I get another panic.  I think I need to fill out a data structure but I do not know what structure.  The Beagle Board xM does not seem to have any structures except the twl4030_platform_data which contains a twl4030_usb_data structure.

The kernel I am using is 2.6.32

Here is a boot log:

Here is the source that prints some of the messages in the log above:

The main question I have is should the function otg_get_transceiver() return a valid pointer when using the SMSC USB3320?  The notes say that some devices do not require a driver.  Is there a structure I need to provide that I am not?

int __init musb_platform_init(struct musb *musb)
{
        u32 l;
        unsigned int stpNum = 0;

#if defined(CONFIG_ARCH_OMAP2430)
        omap_cfg_reg(AE5_2430_USB0HS_STP);
#endif

printk(KERN_INFO "\nWLC DEBUG <<<<Made it to function %s stop %d>>>>>\n", __func__, stpNum++);

        /* We require some kind of external transceiver, hooked
         * up through ULPI.  TWL4030-family PMICs include one,
         * which needs a driver, drivers aren't always needed.
         */
        musb->xceiv = otg_get_transceiver();
        if (!musb->xceiv) {
                pr_err("HS USB OTG: no transceiver configured\n"); // <------------ THIS LINE IS WHAT INDICATES THERE IS NO XCVR
                return -ENODEV;
        }

printk(KERN_INFO "\nWLC DEBUG <<<<Made it to function %s stop %d>>>>>\n", __func__, stpNum++);

        musb_platform_resume(musb);

        l = omap_readl(OTG_SYSCONFIG);
        l &= ~ENABLEWAKEUP;     /* disable wakeup */
        l &= ~NOSTDBY;          /* remove possible nostdby */
        l |= SMARTSTDBY;        /* enable smart standby */
        l &= ~AUTOIDLE;         /* disable auto idle */
        l &= ~NOIDLE;           /* remove possible noidle */

printk(KERN_INFO "\nWLC DEBUG <<<<Made it to function %s stop %d>>>>>\n", __func__, stpNum++);

        /* SMARTIDLE is blocking core to enter off mode in 3630 */
        if (cpu_is_omap3630())
                l |= FORCEIDLE;         /* enable force idle */
        else
                l |= SMARTIDLE;         /* enable smart idle */
        /*
         * MUSB AUTOIDLE don't work in 3430.

OK.  I have resolved the kernel panic by calling the code segment in my board file:

#ifdef CONFIG_NOP_USB_XCEIV
        /* OMAP3EVM uses ISP1504 phy and so register nop transceiver */
        usb_nop_xceiv_register();
#endif

USB still does not work.  Any other ideas of things I should check?

Thanks,

Wayne

Ajay,

My hardware is very similar to the Beagel Board xM (Rev B).

OMAP3530 <--- ULPI ---> USB3320C <---- USB ---> LAN9514  <----- USB HUB PORT[3..0]

The OMAP3530 is in the CUS pkg and is connected to the USB3220 over the HSUSB2 port

Right now I do not see the omap every enumerate the USB and find the LAN9514.  I see two host ports. but nothing else.  Any thoughts on what to check?

Here is my current boot log:

Thanks.

Wayne

wayne,

Have you made sure that the power supplies to USb3320 PHY is configured properly. Refer the board-omap3evm.c file where it does vaux2 supply setup for this phy. You can also look at the schematics and see if anything is needed on power supply setup.

Ajay

Ajay,

We are using the TI TPS650731 which does not have an aux supply for the Phy.  We are using the VDCDC1 (VIO_1V8).

I added some 4.7uF caps to my supply rail for the USB3320 and a wire directly from the 4.7F cap to pin 28 and another wire to pin 30.  There are two caps that decouple the 1.8V rail.  one 0.1uF decouples pins 28 and 30, another decouples pin 32.

Based on looking at the supply rail I am not really thinking this a power supply problem-- at this time it still "smells" like a SW problem.

uBoot configuration for the related pins are:

Hi Wayne,

Excuse me if I am not correct but I am bit confused by your query. You are using USB3320 with OMAP HSUSB2 port which is only a host port. But you are comparing your configuration with the USB OTG port configuartion for which PHY inside PMIC TPS65950 is used in beagle board and PHY from NXP is used in OMAP EVM (option is there to use PMIC PHY in EVM but NXP PHY is used as default). And also it is actually USB3322 that is used in beagle board for USB host port 2, though it is quite similar to USB3320.

Can you please clarify how you are using USB3320 or upload your schematics.

My hardware looks like this:

OMAP (HUSB2) --- ULPI--> USB3220 --- USB ---> LAN9514

This is the same connection as the Beagle Board xM has.

We are using the TPS650371 PMIC which does not have a ULPI port.

Gents,

I'd like to +1 the priority and interest on this thread as the subject of the thread is exactly the thread I was about to propose.

We are doing 100's of connect/disconnect tests for reliability testing.

About 5 to 10% of the time, we get an "unable to enumerate" failure on the EHCI port from the OMAP connected to SMSC USB3220 ULPI.

The October errata for OMAP3525 states that there is no workaround.

Is that still true or is there a patch available for PSP 3.1.0.6 or later (linux 2.6.32 PM for OMAP35xx or later)?

Can a complete disable of PM suspend support or USB suspend support resolve this?

Is this TI part a direct replacement and fix for the issue?

http://focus.ti.com/docs/prod/folders/print/tusb1210.html

Not trying to hijack this thread, but the subject is the same.

I'll create my own post if necessary.

thanks,

Peter Thoeming

Ajay,

I realize this is a response to a very old post, but if the problem is in the SMSC USB3320 PHY's only and the NXP and TI PHY's do not exhibit this, then why is it that there was a change made to the OMAP37xx in revs 1.1 and beyond that removes the issue claimed to be in the SMSC USB3320?

Also, when I view the USB traffic on a Beagle USB 480 Analyzer, there are always SOF packets sent out by the Host, therefore preventing any device from ever going into a USB suspend state because they never see a 3ms duration of inactivity.

That is what we have observed with both HID-class and MSD-class devices.

We are using PSP3.0.1.6 on OMAP3525, configured with CONFIG_USB_SUSPEND=y.

Therefore, this whole discussion doesn't make complete sense yet to me:

1. The kernel provided for use on OMAP35xx silicon doesn't even allow suspend to occur, thus avoiding any chance of such a lock-up occurring

2. The OMAP35xx/37xx errata sheets are not clear in their advisory notes regarding what exactly is wrong with receiving a "DIR signal 3 clock cycles"

3. Upon disconnects, the bus does enter one false "SUSPEND" state briefly and the last waveform captures of both the TI TUSB1210 and the SMSC USB3220 have a DIR signal pulse active-high during the falling edge of the CLOCK at exactly the 3rd cycle after STP is de-asserted by the OMAP EHCI controller.

4. The OMAP37xx advisory 1.63 states that this issue is fixed in the OMAP silicon revs 1.1 and 1.2

I guess my first question should really be, why is the kernel configured for the OMAP EHCI controller such that it never allows the peripherals to self-enter suspend mode on 3ms of inactivity as per the USB2.0 spec?

I've done more research while waiting and realize that this interoperability issue is most likely not the issue we are seeing that is causing bus-lock-up. Most likely it is libusb SW IP we're using to talk to a special HID device.

However, I still have a question in regards to my own comments enumerated above:

First, here are my comments to my own comments:

1. The kernel and EHCI controller are behaving as required as per USB2.0 sections 7.1.7.6 and 8.4.3. This is normal and, as a result, USB suspend does not occur.

2. & 3. & 4. The OMAP35xx/37xx errata sheets are not clear in their advisory notes regarding what exactly is wrong with receiving a "DIR signal 3 clock cycles". Here, I have found that while the waveforms look the same at a SUSPENDM that occurs at final disconnect, there is a timing difference that may account for the errata listed in the OMAP errata document.

The SMSC errata document does state there are some potential timing-related issues for revs A and B of the OMAP3320 when using an external 60MHz clock, as we are doing.

Is that what accounts for the TI errata for interop on this part? The SMSC timing when using external 60MHz clock source?

if we're never allowing SUSPEND, is it safe to assume we'll never see this issue?

Is TUSB1210 pin to pin / function to function compatible with SMSC USB3320. If I replace SMSC USB3320 of already manufactured board with TUSB1210, will it work?
