AM5748: AM5748 I2C2 bus intermittently hangs

Viktorija,

Do you know which device is holding SDA low?  For example, if you change the i2c2_sda pinmux to "driver off" that will give you definitive information as to whether the AM57xx is responsible for holding the line low.  Since you said this is a read, I suspect it is the other device holding the line low.  Assuming that changing the AM57xx pin mux does not release the line, you still should try to confirm which device is holding the line.  Is there a "reset" pin for the device on the other side?  It would seem most likely that the device from which you are reading is the device having an issue, but we should try to prove that is really the case.  Another way to do it (more invasive) would be to physically remove the other devices from the board and confirm that you can still recreate the same issue with only a single device on the bus.

Are you able to post a more zoomed in version of that same picture?  When performing an I2C read, the AM57xx is expected to NACK the last transfer such that the other device knows not to try and send more data.  You can run into these lockup situations if the AM57xx is not NACKing that transaction.  I thought that all happened in hardware, but it would be good to see a zoomed in photo to confirm that the AM57xx is indeed NACKing the byte before the bus hangs.

Also -- what software is running where you see this issue?  Is it u-boot?  Have you been able to boot all the way to the kernel?  Do you ever experience the same issue in Linux or does it strictly occur when u-boot is running?

Best regards,
Brad

Hi Brad,

   I'm Ron, the guy with the problem. I will verify which device is holding SDA low but my strong suspicion is it is the salve device at 0x4b. Since the 5748 ACKd the first data beat, the slave device is still offering data but the master is not sending any clocks. I know the data at this location is 0x00 so the SDA will be asserted low. I believe the real issue is why the 5748 is ACKing the first data when the read is a 1-byte transaction.

   Will get back to you on the definitive answer of who is holding the SDA low.

       Many thanks, Ron.

HI Brad,

   Confirming that the slave device at 4B is holding SDA low. On asserting the chip reset, SDA releases and the 5748 recovers. So the real issue is why the 5748 is ACKing the data.

   Thanks, Ron.

Hi Ron,

You're sure the processor is ACKing that data?  Is that true of all reads, but in cases where the next bit is 1 the bus doesn't hang?  What is the software being used?  It sounds like the ACK is the root cause of the failure so we need to look into the software.

Best regards,
Brad

HI Brad,

   Here is an expanded view of the failing transaction showing the transaction is NAKd. Ron

The picture didn't come through.  If the transaction was NACK'd that is the proper behavior.  Does the processor ACK or NACK just before the bus hang?

HI Brad,

   Not sure if you can see the picture or not. Anyway, We are using u-boot. I need to ask the SW person for details. Should I have him zip up the I2C files and can I send them somewhere?

Thanks, Ron.

My bad, transaction is ACKd, the incorrect behavior. Sorry! Ron.

Rather than sending me code, I would rather just know the details of the release.  Is this u-boot that came from a TI SDK?  If so, which version?

Here you are!

I received your picture.  Thanks.  We already knew the issue, but it's good to have the substantiating evidence.  Here's my markup:

Please send details on the software so we can understand that better.  Also, what is this specific device you're talking to?  I may need to look at its associated driver.

HI Brad,

   Here is what our SW person tells me:

It was pulled from an SDK. It’s been so long. I thinks it’s one of these two versions.

ti-processor-sdk-linux-am57xx-evm-04.01.00.06-Linux-x86-Install

ti-processor-sdk-linux-am57xx-evm-05.01.00.11-Linux-x86-Install

The u-boot version is U-Boot 2018.03-rc3

The device at 4B is an AD9545. Don't forget the same device runs OK on a previous version of our module.

Thanks, Ron

It must be the 5.01 version because that's the one on the 2018 branch.  The 4.01 used a u-boot 2017 branch.

I had a quick look at the I2C driver bundled there.  Surprisingly there have been very few patches between then and now.  I don't see any patches to the TI I2C driver that look similar to this issue.  Can you tell me where the AD9545 comes from, i.e. is the driver already in the u-boot tree?  If not, where did it come from?  Perhaps the issue is in the way the AD9545 is trying to perform the I2C transactions?

I acknowledge there are a lot of inconsistencies...  If there was an issue in the AD9545 driver, I would not have expected it to work on the other I2C.  We need to keep digging for some new data points until we uncover one that helps lead us to the answer...

So do you see this same issue on all devices (of the same board revision)?  And can you always reproduce the issue by reading the exact same address?  Have you tried reading that same address on the older hardware revision where a different I2C bus was used?

Hi Brad,

   We have no specific driver for the 9545 in u-boot so I suppose it uses the generic driver. The failure is not seen at any definite point in the script. The only consistency is the mode of failure; a read that does not complete as seen above. But it always happens early in the script, after less that twenty or thirty transactions. It smells of a race condition: either the master is asserting ACK instead of NAK or the slave thinks it is a write and is asserting ACK (or just asserting SDA for no good reason). Ideas on how to separate that out? My impression is that the master thinks it has completed the transaction since I can ask it to do another transaction and it complains it cannot but after the SDA release, it can successfully.

   Assuming the master read state machine is well behaved, this error would indicate that the instruction was read wrong and it thinks it is a multi-byte read. is it possible that the memory used for the transaction is being used by something else? I've seen this sort of thing where different processes get allocated overlapping memory. Results are really messy.

   I have asked our SW guy to run my script on his board and see what happens. I know that we do share the issue where occasionally I2C2 cones up with SDA already low and where SDA is not low but transactions fail.

   That's the story so far . . .

Many thanks, Ron

Can you distill your script down to a handful of commands that you can make fail repeatedly?  At that point, can you share it here for review?

You and I are heading in the same direction! if I perform "i2c md 4b 100.2 1" one at a time, I can get it to fail after as few as two attempts (usually quite a few more). And I did an interesting thing; I upped the gain on the SDA to hopefully reveal who was performing the "ACK" and, voila, it looks like the 5748. Observe the low level of the address and the low level of the read data. My interpretation would be that the master is asserting the ACK. 

You can see the assertion of SDA by the master to end the cycle but the slave is asserting low also, causing the difference, and when the master releases, the slave takes over slightly raising the low voltage. Ron

You read my mind on verifying that it was the processor that performed the ACK.  I assumed that to be the case, but it's good to check assumptions in these types of situations.

Has the bus speed changed at all between the working and non-working scenarios?

HI Brad,

   No, the bus speed is 400KHz (well, ~384KHz) and that is the same for current and previous modules. BTW, reducing the speed to 100KHz makes no difference to the issue. I have asked our production crew to lend me another module so I can have two at home to play with. Never know!

   A  segway to something else. Could I have a physical issue on this board, like a pad missing and not providing a ground or power or something else? Clearly not the I2C pins but something else? Suggestions? If a state machine is making a mistake SOMETIMES, it might be internal SI if a GND is missing. A28 is a GND and that is in the corner. Corners are vulnerable to not soldering properly. Having said that, we have a very good track record of soldering the AM5748 chips down (we do our own manufacturing), And it looks OK but hard to tell with lead free and no microscope at home. But a thought . . .

Hmmm.  Hopefully I'm not making a silly mistake, but looking at your last screenshot, I would not have guessed 400 kHz.  It looked like 50us/division.  Over a span of 2 divisions (100 us) I counted almost exactly 5 clock periods.  I was estimating 20us/clock which corresponds to 50 kHz.  Am I making a mistake in my estimate?  Or perhaps is the actual speed not what you were expecting?

You said this was I2C2 right?  I'd like to have you read a couple of registers after a failure, but I want to provide you the correct address.

Look at trace Z4, the zoomed clock. In the green box below you will see 6.5us/div. 18 clock cycles take 7 and a bit divisions = ~46ns makes ~2.56nS per clock make ~391KHz. The zoom gets me every time too.

Let me know what regs you want. I'm assuming somewhere in the 0x48072000 group (I2C2) but maybe not.

Ron.

. . . of course I mean uS, not nS, sorry!

Possibly jumping the gun but here is what I think you might be interested in.

Were you watching the scope as you did these transactions?  In particular I'm wondering if you saw the above error messages on the iteration where the bus locked up.  Or did the bus lockup first, and on the following attempt to read from the bus you got the above error?

Are you able to have your software team add some instrumentation into the I2C driver?

File:drivers/i2c/omap24xx_i2c.c

Function: __omap24_i2c_read()

In particular:

1. Can you print out the arguments that were passed into the functions?

2. This is a bit of a shot in the dark based on past I2C issues, but can you stick a delay such as udelay(1000) between the "write" and "read" portions of the transaction?  If my file is the same as yours, I see a comment "Set slave address" at line 526.  That represents the beginning of the receive logic for the I2C read.  A delay right there would be perfect.

3. Just a few lines after the above delay there's a while(1) loop for reading the data.  Just before that loop please print the values of  CNT and CON registers (i.e. just after you write them).

To give you insight into why I've requested these specific items, I've seen in the past that the state machine timing can be very finicky.  What I think could possibly be happening is that if somehow the write of CNT=1 isn't registering properly with the hardware, that it might still be attempting to use a CNT=2 (i.e. from when the address was written). I'm sure there are plenty of holes in my theory, but some observations from your side based on these suggestions would be a big help for starters.

Thanks!

Brad

HI Brad,

   We tried putting in the delay but that did not help. We are working on the debug stuff now so hopefully more feedback later today. Ron.

Hi Brad,

   Here is what our SW person said:

Here is something to test with. The output doesn’t make much sense but that could be because alen is reporting zero, which might be where the problem lies. That’s why the second debug output he requested is not being displayed.

  Here is where the script fell off the cliff with a few instruction before (ignore the unknown command stuff):

HI Brad,

   From Bill, our SW guru:

I think they need to take a look at this function in that file

static int omap_i2c_xfer(struct udevice *bus, struct i2c_msg *msg, int nmsgs)

it calls the read/write function but zeroes addr and alen

static int omap_i2c_xfer(struct udevice *bus, struct i2c_msg *msg, int nmsgs)

{

        struct omap_i2c *priv = dev_get_priv(bus);

        int ret;

        debug("i2c_xfer: %d messages\n", nmsgs);

        for (; nmsgs > 0; nmsgs--, msg++) {

                debug("i2c_xfer: chip=0x%x, len=0x%x\n", msg->addr, msg->len);

                if (msg->flags & I2C_M_RD) {

                        ret = __omap24_i2c_read(priv->regs                                               

     priv->waitdelay,

                                                msg->addr, 0, 0, msg->buf,

                                                msg->len);

                } else {

                        return -EREMOTEIO;

                }

        return 0;

Ah, yes.  It looks like an upper level of the driver is implicitly breaking down a "read" command into two messages, a write followed by a read.  That's fine.  There's one other place where there might be a timing issue.  Can you also try adding a udelay(1000) at the rd_exit label, i.e. just before the flush_fifo command?

On a related note, are you able to perform similar tests from Linux using i2cset/i2cget commands?  In general I expect the Linux drivers to be more robust than the u-boot drivers.  If everything works flawlessly all the time from Linux that will at least confirm that we've got an issue in the u-boot drivers somewhere.

HI Brad,

   We're making progress. Adding the last delay fixes our u-boot issues. Unfortunately we are seeing similar issues when we boot the kernel. Where do we add the delays for that?

   Many thanks, Ron

That's great news!  By the way, I think we can clean up the u-boot fix slightly.  First, I think the location should be slightly different.  I think the delay should be after the flush_fifo and not before.  Second, rather than using udelay(1000), I recommend polling for I2C_CON[10] (MST) to clear.    The MST bit self-clears when the transaction is complete.  I've seen this in the past on other devices, i.e. for back-to-back transactions you need to make sure MST has cleared before initiating the next transaction.  Will you please try that out and let me know if it continues to work?  I think it's a bit more correct than simply inserting a delay which feels admittedly like a hack.

HI Brad,

   We will try that. Also, what and where should the same fix for the kernel go? Thanks, ROn.

Hi Brad,

   SW say they'd rather not go backwards at this moment but can we please have the kernel fix? Many thanks, Ron.

I was looking at the kernel code in parallel.  Can you tell me more about how you recreate the issue for example:

1. Are you using i2cset/i2cget commands from a script?

2. Does putting a delay between commands "fix" the issue?

3. Are you seeing the same failure, e.g. can you see the controller ACKing the final transaction when acting as master receiver?

The Linux kernel driver is a bit more complex than the u-boot driver.  It supports both interrupts and polling.  It will take some study to determine the appropriate fix. I need to know if MST self-clears when the transaction ends.  I'm pretty sure it does, but if your software team could please spend a few minutes to re-run that other test, it would help clarify the path forward.

HI Brad,

   About 4 seconds or so into the kernel boot, the same I2C device that formally failed the script initialization in u-boot gets initialized by some code we wrote to initialize the device. So there is a huge flurry of transactions, similar to the script. After about 10mS or more, one of the write transactions fails and it looks identical to what I previously sent you. So the I2C bus gets stuck with the SDA line low, just the same. 

       Ron.

HI Brad,

   Let me know if you need any more info. Ron.

For now I'll assume that the MST bit self-clears as I recall.  The issue of too little time between transfers only happens when there are back-to-back transfers.  While you could enforce this at the end of the transaction, from a CPU perspective I think it is better to check it at the start of the transaction.  

This would be my first thought of how to fix it:

static int omap_i2c_xfer_msg(struct i2c_adapter *adap,
struct i2c_msg *msg, int stop, bool polling)
{
struct omap_i2c_dev *omap = i2c_get_adapdata(adap);
unsigned long timeout;
u16 w, con_reg;
int ret;

dev_dbg(omap->dev, "addr: 0x%04x, len: %d, flags: 0x%x, stop: %d\n",
msg->addr, msg->len, msg->flags, stop);

con_reg = omap_i2c_read_reg(omap, OMAP_I2C_CON_REG);
if ( con_reg & OMAP_I2C_CON_MST )
     return -EAGAIN;

omap->receiver = !!(msg->flags & I2C_M_RD);
omap_i2c_resize_fifo(omap, msg->len, omap->receiver);

Please try it out.

HI Brad,

   Sorry, that did not work. Here is the code as returned from our SW people. Hopefully we did what you asked:

here is the code snippet

/*

 * Low level master read/write transaction.

 */

static int omap_i2c_xfer_msg(struct i2c_adapter *adap,

              struct i2c_msg *msg, int stop)

   unsigned long timeout;

   u16 w, con_reg;

   dev_dbg(omap->dev, "addr: 0x%04x, len: %d, flags: 0x%x, stop: %d\n",

      return -EINVAL;

   con_reg = omap_i2c_read_reg(omap, OMAP_I2C_CON_REG);

   if ( con_reg & OMAP_I2C_CON_MST )

      return -EAGAIN;

   omap->receiver = !!(msg->flags & I2C_M_RD);

   omap_i2c_resize_fifo(omap, msg->len, omap->receiver);

   omap_i2c_write_reg(omap, OMAP_I2C_SA_REG, msg->addr);

   /* REVISIT: Could the STB bit of I2C_CON be used with probing? */

   omap->buf = msg->buf;

   omap->buf_len = msg->len;

   /* make sure writes to omap->buf_len are ordered */

   barrier();

   omap_i2c_write_reg(omap, OMAP_I2C_CNT_REG, omap->buf_len);

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Here is what I see on the i2c bus:

When I monitor the accesses to the AD9545 on I2C2, I see an initial access of a 2-byte write (successful) but the SCL line is now jammed low!!! ~ 1 second later I see one high/low pulse on the clock line and the data line SDA goes low and stays there for ~ 2.6 seconds when both SDA and SCL go high (presumably a reset of some kind). Something like 6mS later there is another transaction: it’s a 1-byte write to location (7-bit) 0x20 with data 0x0a (successful). The transaction ends the same as previous with the data line held low.

   So, if anything, things got a lot worse.

       Ron.

Ok, maybe that was too fancy.  Let's try something a bit simpler and more straight forward.  Further down in omap_i2c_xfer_msg is the following:

if (timeout == 0) {
dev_err(omap->dev, "controller timed out\n");
omap_i2c_reset(omap);
__omap_i2c_init(omap);
return -ETIMEDOUT;
}

if (likely(!omap->cmd_err))
return 0;

I believe that "return 0" statement is the normal place where the function would return.  Can you try putting a delay right there?  Maybe this:

if (likely(!omap->cmd_err))
{
mdelay(1);
return 0;
}

Let's see if it works first.  If it does, perhaps we can do something a little cleaner like watching for the MST bit to transition.  I just want to be careful not to eat up a bunch of CPU polling a bit. 

Brad

HI Brad,

   Sorry, that didn't help either. But it didn't change the character of the original failure either. Still ending up with SDA stuck low. And for a warm board, all the way up with no errors. 

   Next?

       Thanks, Ron.

Can you put a couple printk's in there?  Maybe 1 following the mdelay(1) and another after that "if" statement, i.e. so you can see how often you actually are going beyond that part of the code?

Hi Brad,

   Here is the console spew with the prints:

That looks mostly like I expected, i.e. generally no errors reported.  I'm surprised that didn't work.

I think it would be nearly the same, but another change would be inside omap_i2c_xfer to add a delay/sleep there.  For example:

omap_i2c_wait_for_bb(omap);

mdelay(1);

if (omap->set_mpu_wkup_lat != NULL)
omap->set_mpu_wkup_lat(omap->dev, -1);

out:
pm_runtime_mark_last_busy(omap->dev);
pm_runtime_put_autosuspend(omap->dev);

If that still doesn't work can you please print the value of the CON register immediately following that mdelay?

Morning Brad,

   No joy so far. Hopefully this is what you need. Many thanks, Ron.

HI Brad,

   As a hardware engineer and not having a lot of knowledge about SW nuances, looking at the failure mode and reviewing the TRM, this is my opinion of what I think might be the root cause. Just looking at this from a hardware perspective. It might provoke a useful thought. If not, sorry for wasting your time.

   Since I2C accesses seem to work when the chip is warm; that indicates a HW race condition. Seems we managed to preempt that in u-boot by the delay. However, apparently not so easy for Linux.

   Looking at Figure 24-21. HS I2C Master Receiver Mode, Polling Method, in F/S and HS Modesin the TRM, the core loop is Read  I2Ci.I2C_IRQSTATUS_RAW register and save value. All decisions are based off of what is read. For something to be read wrong but fixes as the chip gets warmer smacks of either setup and hold issues or synchronizer issues. Either way, let us assume that 2C_IRQSTATUS_RAW reads wrong. The only real way to "fix" that is to read the register two or three times in succession. If the second read equals the first read then you done but if it's different, a third read is required and that should equal the second read. Without knowing how the synchronization is done, this is largely conjecture.

   A dumb question: are you sure that you really are reading 2C_IRQSTATUS_RAW and not a cached value? Register, of course should not be cached.

   In my mind there is no question the underlying issue is a hardware race condition. However, if we can "fix" it for u-boot, I'm sure we'll find a way in Linux

   Just a few thoughts! All your efforts are very much appreciated

       Thanks for you attention,

             Ron.

This is new info to me.  If I missed it in a previous response I apologize.  Are you saying this behavior is temperature dependent?  Was that true for the u-boot issue too?

I also want to note that it is concerning to me that you're seeing issues even with the Linux driver.  For u-boot, it's not used quite as heavily as the Linux driver, so I was willing to believe that maybe there's a corner case where a timing error was lurking.  For Linux however, that seems very hard to imagine.  This I2C driver is heavily used across many SoC's and across many, many customer designs.  And furthermore the register outputs you've shared so far do not look like they suffered from the same issue as the u-boot driver.

All this being said, I'm not sure this software path is the right way to go.  Even from the start it seemed highly unusual that the issue popped up when you moved the device to a different I2C controller.  Question: How many other I2C devices are on this same I2C bus?  Is it possible to remove the other devices?  While I know you performed a test where you showed conclusively that the ACK had a different level than the rest of the data, that really only showed that it was not your slave device sending the ACK.  It did not conclusively prove it was the AM57xx.  Removing the other devices would prove that.  Removing the other devices would also change the bus capacitance -- could that be related?

In short, while some decent progress has been made, it is still not entirely clear to me whether this issue is hardware or software related, and it's also not clear if there is a single issue being observed or perhaps a combination of multiple issues impacting us at different times.

That would be a major error in the driver.  I don't think that's the case.  We'd be seeing issues everywhere.

Hi Brad,

   Sorry for not emphasizing the temperature aspect more, Guess it got lost in the avalanche. The script in u-boot allows us to initialize the ad9545, not normally done there. When Linux starts, the AD9545 is initialized about 4 seconds in. Both scenarios fail the same way, with SDA stuck low. You were able to "fix" the issue in u-boot with the delay.

   We are seeing the issue across three boards: I am seeing it, the SW engineer is seeing it and I have another engineer who is seeing it. Normally this board is attached to another, which changes the loading on the I2C bus.

   For the old board, the AD9545 was on I2C4 together with 2 temp. sensors, a fiber link device and a DVI device. I2C4 was entirely on the processor board and we never saw any issues

   On the new board, the AD9545 is on I2C2, a bus which connects to the second board. On the processor board also live the same two temp. sensors. On the attached board also live a codec, an FPGA (I2C slave implemented) another temperature sensor and a USB power device. It seems to make little difference if the second board is there or not, the same failure occurs.

   On the old board, i2C2 had no loads on the processor board but had three loads on the attached board: a temp. sensor, a codec, and an FPGA, same as paragraph above

   I do not have the means at home to remove devices from the board. If you think the removal is really needed, I will take the board into work and get it done. There is no software way of disabling them. But, like you thought about my cache idea, I think someone else responding with the ACK is extremely unlikely. If the SI were bad, I could believe maybe, but the the SI is good!

   It's not like the I2C fails on the first I2C transaction. The most recent capture I have of the I2C bus shows major activity for nearly 200mS, that's a lot of transaction. And then it finally fails.

   Let me know if you have more questions.

       Thanks, Ron

HI Brad,

   This is interesting. Usually I see the failure on a read but here I see it on a write. And we're one clock short. Something not right!

And now the board is warm, it runs fine. Here is what should have happened:

What do you make of this?

Ron

What voltage do you measure on your VDD rail?  Can you also read the 32-bit register at address 0x4A0025F4?  If you can get to a Linux prompt you can do "devmem2 0x4A0025F4" to read it.  Or in u-boot it would be the md command.

HI Brad,

   VDD - there are so many of them. DO you mean core? Or do you mean something else? Ron

I'm talking about "VDD" specifically, yes the core domain:
