TPS65987D: Advertise Mask not working

Florian Kaffanke

Prodigy 170 points

Part Number: TPS65987D

I can't get the option Advertise only if Externally Powered to work. I'm using two TPS65987EVM evaluation modules:

One called Host: EVM with the default out of the box configuration
One called Device: EVM that is optionally externally powered, custom configuration. Dual power role, default role is sink, Barrel Jack Detect Event is enabled to make it a source when externally powerd.

My Transmit Source Capabilities are as follows (0x32):

Without an external power supply, only PDO1 is advertised. The settings 5 V, 0 A for a sink only should be in accordance with USB PD 3.1 specification (section 6.4.1.2.2)
With an external power supply (20 V), PDO2 to PDO4 should also be advertised. But they aren't. Only PDO1 is advertised (which leads to a CapabilityMismatch during PD conctract renegotiation because of the 0 A). And it doesn't matter if the Device is externally powered before or after the USB-C connection is established. The Barrel Jack Detect Event is triggerd, since the Externally Powered flag is set properly.

There's a different way of changing configurations described in slvae11a section 3.2 which is much more complicated. I've not tested it yet, because I would prefer the simpler solution (because of KISS: "Keep it simple, stupid!")

Good Afternoon Florian,

Would you be able to provide me the project (.pjt) file? That will help me find the root of your issue.

Kind regards,

Conner Gillette

I see you have the Barrel_Jack_Event input GPIO configured for GPIO21. Are you able to confirm that this input is rising to logical 1 upon barrel jack plugin and that the dead battery flag is being cleared? (You can see this in the Debug mode or using a scope).

Are you also able to get the PD negotiation logs? I want to see the source capabilities that are sent and the requested PDO from the sink.

Kind regards,

Conner Gillette

Hi Conner,

I checked the PGOOD signal with a scope. It becomes logic high when I apply external power.

The dead battery flag is TRUE when there is no external power. It becomes FALSE when I switch on the external power. The Extermally Powered Flag also changes from FALSE to TRUE.
I'm using a devboard (USB Type-C and Power Delivery Discovery kit) to get the PD negotiation logs. I'm not sure how helpful this is. But here is logfile:

I changed some of the PDO settings in the meantime but the outcome is always the same.
The Host is externally powered, the Device is not.
I plug in the USB cable and the Device becomes the power sink
I plug in the external power supply of the Device and it issues a PR_SWAP (line 80).
The advertised PDO is still only [1] Fixed : 5V - 0A

This is all very helpful, thank you. I apologize for asking you for more information, but I can't see a root cause to the problem yet (I've only been able to rule out causes). Would you be able to go into 'Debug' mode (from the top ribbon), then once connected, go to 'Debug' > 'Take Snapshot' and send me the output files? (This will allow me to see the state of all registers when the 5V 0A source PDO is negotiated).

Kind regards,

Conner

Hi, I really appreciate your help. If you need more information don't hesitate to ask.

I took two snapshots from both EVMs:

snapshot_device_ext_unpowered.txt & snapshot_host_ext_powered.txt: Both EVMs connected via USB cable, only the Host is externally powered
snapshot_device_ext_powered.txt & snapshot_host_usb_powered.txt: Snapshot after I switched external supply of the Device on

I compared the files from before and after the power role switch with a diff tool which was quite insightful. However, I still have no idea what's wrong.

Best regards,

Florian

Hi Conner,

do you have any updates? Or can you provide a project file (with any configuration) where the Advertise only if Externally Powered option works? This would help as as starting point.

Best regards,

Florian

Hi Florian,

Apologies for any delay, this was just handed over to me and I am now working on reviewing these and trying to discern any useful information or an update for you, but need more time go over and understand the snapshots myself.

Thanks,
Field

Hi Florian,

Using a python script I developed to determine the differences between the two snapshots, I was able to develop the corresponding documents which state the discrepancies between values/registers in the documents you gave me.

Host_Diff.txt --- This is the difference between the < snapshot_host_ext_powered.txt > and < snapshot_host_usb_powered.txt >. This one was a little trickier as there were missing values/rows so I had to insert NULL values in order to make the comparison correct and more reading-friendly. Note that where you see a NULL value in this document there is no value at all/this does not exist for this document. This should be under the received source/sink capabilities section.

If you were interested you should be able to use the following information within the documents I generated and ctrl+f within the documents you gave me to find which specific registers these lay under. Unfortunately I am still unfamiliar, and still need to continue to pour through the differences myself and discern the issue. However due to government service I will out of office tomorrow (24AUG) and perhaps possibly (25AUG), so please expect some delay.

Thanks,
Field

Hi Field,

thanks for taking care of my issue. Just in case you were wondering about the gibberish in the log files like PK •FWÈFë\sÛ sÛ * DI Box, port 1 Configuration Registers.txt: I saved the snapshots as .txt files. I realized later that the snapshots are uncompressd zip files. You can change back the extension to zip if you want the orignal files.

I will be out of office for the next two weeks and won't be able to reply. So take you time.

Regards,

Florian

Hi Florian,

After further digging into this issue with another expert, I believe the correct method of resolving this would need to be through changing the configuration, and not using the KISS method. You will need to go in and change register 0x37 and make sure the following are all the values that you desire and what I believe:

Byte 1 bit 2. I believe this needs to be set to a 0.
Byte 2 bit 0. For this one you will want to set this to a 0
Byte 3-4 bit 9:0. Make sure these are set to the correct value.

There may be more changes that are needed, but these may alleviate the/some concerns.

Thanks,
Field

Hi Field,

sorry for the delay. Thanks for your message. I changed the suggested register values.

The advertised current is still 0 A. Even if I power up the EVM configured as the device first, it advertises 5 V, 0A only.

And I checked again the value in 0x29: Externally powered. It changes accordingly when I turn the power on or off. However it doesn't "activate" the PDOs 2,3 and 4 that are configured as Advertise only if Externally powered PDOs.

Best regards,

Florian

Hi Florian,

No problem, I hope you enjoyed your vacation/time out! Interesting, I will dive into this. Are you still using the usb_device_advanced.pjt that you linked earlier in this thread?

Thanks,

Hi Field,

thanks, I had a great vacation :-)
In the meantime I made some changes to the project file to get it more towards a configuration that's suitable for our final product. I kinda lost track of the changes I've made so far :-(. I've uploaded the current versions of the usb_device and usb_host project which are currently frozen (aside from changes we discuss here).
I'm using the EVMs with their default jumper configuration. You should be able to replicate the behaviour if you have two EVMs at hand and flash them with the configurations.

Best regards,
Florian

Hi Florian,

After diving through again, it appears that GPIO21 may not be high for either device when the device is 'externally powered', but believe this only pertains to the 'usb_device'.

Could you ensure when you are doing this/externally powering the device, that you are driving this pin high? This may have some effect here.

What could or may not help, can you go into the ACT and go to the tab labeled 'Port Control' and select the box for 'Externally Powered' and seeing if this helps? This is currently selected for the usb_host, but not for the usb_device. The following .bin file should also have this change implemented (and only that), but if it does not work feel free to do the above implementation I described. https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/196/usb_5F00_device_5F00_advanced_5F00_edit.bin

Thanks,
Field

0 Florian Kaffanke over 1 year ago in reply to Field Tolson

Hi Field,

thanks for your answer. You are right with your observation about the state of GPIO21: it doesn't ever change. I captured the ACT in debugging mode as an animated gif (don't know if ithe animation will play). GPIO21 Data stays at 0x0 while Externally Powered in the Port Control register changes accordingly when switching the external power supply. I also followed your recommendation to set the Externally Powered bit to 1 in the configuration file which didn't help. Apparently it changes dynamically to represent the actual status of the system. Any preset value is overwritten.

The last two screenshot show the voltage at GPIO21 and of PWR_SYS just to ensure the hardware works as intended. And for me it looks OK: GPIO21 follows the external supply voltage.

Best regards,

Florian

0 Field Tolson over 1 year ago in reply to Florian Kaffanke

TI__Genius 10772 points

Hi Florian,

Yes, as I figured but was worth a try. I don't know why GPIO21 is not high, but it obviously responds accordingly as even in those debug files the device tested as 'True' for being externally powered. And based on your oscilloscope it is also high and the device reacts accordingly.

Using two EVM's it looks like I was able to get 0.9A advertised after making some changes, but nothing more than this with the PDOs being set to 3A, including this one..

And it looks like the sink was advertising as I had set up as well.

This makes me think that there is some limit in place, but I am unable to immediately find this or where the issue relies. But upon developing a new project (instead of using the usb_device) and changing the PDOs, they are all advertised except the PDO I selected as ''advertise if externally powered''. Which may mean this is where the issue lies, but again I was unable to find anything immediately that remedied this. And it may be some combination of factors.

Please allow me a little more time to continue testing with the EVM's and I apologize for the delay and time this has taken.

Thanks,
Field

Hi Field,

thanks a lot for you efforts! I really appreciate it. And it's great to see you've made some progress.

We are still in the early stage of product develpment, so it's not too time critical. What's more important to me is that I have confidence that a solution can be found. And getting supported certainly helps with the confidence .

Best regards,

Florian

TI__Genius 10772 points

Hi Florian,

It is much appreciated

After some tinkering it looks like I was able to get the 'Advertise only if Externally Powered' to work using and configuring a fresh project or using some changes to your usb_device project as well:

Please try the following .bin file: https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/196/8686.usb_5F00_device_5F00_advanced_5F00_edit.bin

0 Florian Kaffanke over 1 year ago in reply to Field Tolson

Prodigy 170 points

Hi Field,

thanks again for your help. Unfortunately I got sick last week and couldn't test your bin file.

I've tested it now and can confrim that the advertising of the PDOs works! But there's still something wrong. The actual role swap seems to last only for a brief moment. Its hard for me to decode the PD logs (see screenshots, order left to right). But when I look at the voltage indicator LEDs on the EVMs, it seems that the device delivers 5V for a fraction of a second ("5V" LED lights up). After that the LED turns off again and the "5V" LED on the Host Device lights up agin. It seems that there is a "EVENT_DETACHED" that causes this and resets roles.

If I switch off the power of the USB Host later on (fifth screenshot) to force it into sink mode, the Host EVM ends up in an infinite reboot loop. Could this be a hardware problem where the (Fast) Role Swap is to slow (to little capácity)?

And another question: What did you change in your project? Could you please share the project file instead of the bin file?

Best regards,

Florian

Hi Florian,

Of course, here is the .pjt file that I used to generate the .bin file: usb_device_advanced_edit.pjt. The change I made to the project was to use the bank 1 PDO's instead of bank 0 PDO's, and obviously changing the bank 1 PDO's to mirror the bank 0 PDO's that you had set up. And I also enabled the active bank to follow external power.

I am noticing this issue as well, and do not know why. I made several attempts to resolve this, but all seemed to be futile in the end. So I will need more time to dive into this and see what I can find and give you.

Thanks,
Field

0 Florian Kaffanke over 1 year ago in reply to Field Tolson

Hi Field,

thanks for the project file. Yesterday I made a snapshot from the EVM with your binary file figured out you were using bank 1 :-). I've been fiddeling around with various changes based on that. And it seems I got a working solution, although I don't know why: I simpy "removed" PDO1 of bank 1 by shifting the subsequent PDOs. Bank 1 now has only 3 PDOs: 5V, 9V and 12V all with currents bigger than 0A and all set to "Always Advertise". With this configuration the USB Device becomes a 15 V power source as soon as I switch on the USB Device supply. Switching off the USB Host supply afterwards works as well as going back the whole sequence. But I have the feeling that your configuration should be right one. I'm going to do more tests in the next week.

Here's the diff form the configuration register snapshot from your binary file and mine as described above. The latter is based on my original project. Both snapshots were taken after power up without any USB connections. Besides the intentional changes to bank 1 I made, there is a change in the interrupt mask and various IDs differ. Do you this is relevant for different behaviour?

Hi Florian,

Similar to what you are saying, it looks like the problem originates from the first contract being 5V 0A, no matter where. Using this contract on bank 0 also produces this error. Until I increase the amperage to be 5V 3A, then the contracts work, but 5V 1A and 5V 2A did not work and produced the same output we saw before. But, still using the 'advertise only if externally powered' also works (on bank 1).

And adding in an additional PDO to bank 1 (I used 20V 1.2A) worked/this PDO was advertised. I looked into the 'minimum power' but since 1/2A did not take, I do not think this is the problem. Would this solution be okay for your design?

These other changes, should be irrelevant. When trying to resolve these issues initially, I made changes to some of the masks, but to no avail and reverted my changes to them. I believe these changes are from us making different changes to the implementation.

Please let me know if this okay or works for you, or what you think

Thanks,
Field

Hi Field,

your analysis sound very reaonable for to me. I guess the PDO1 on bank 1 being set to 3A is OK. Since bank 1 is only active when external power is applied. So far I couldn't any problems while testing with this configuration. I guess this really solves my problem then . Thanks a lot for your help and for bearing with me over the last couple of weeks .

Best regards,

Florian
