​

Thanks Brad for your inputs.. Can you please also clarify a doubt below relating to questions asked last time and an issue in TPS6598X Application Customization tool,

From your points it is clear that all configuration ID's are going to support 4Lane DP so USB shall be only 2.0. However in few CFG ID's (ID - 1, 2, 3, 6, 7), the mux select lines is giving out logic levels for 2ch USB + 2ch DP mode (AMSEL->L, POL->H/L, EN->H). So in this case because of Multifucntion bit=0, the entire USB3.0(including USB2.0) is not working. Is my understanding right Brad ?

Regarding the TPS6598X Application Customization tool usage I am seeing an exception message(as attached) pop-up on selecting TPS65986 device. Can you also help on this issue ? Only after this I can start working on generating a new firmware image with the Multi function Preferred bit set..

Thanks Brad for clarifying multi function option.

I am using TPS6598x Application Customization Tool Version 2.10 only.. I tried re-installing the tool as well but still the error persist..

This error comes only when I select TPS65986. If I select TPS65982 the project is loading and I am able see the register settings. Please help..

Hi Brad,

Sorry for the delay..

1. I am using below flow for loading the template file. Attached the screen shot also for your quick reference.

     Project->New Project -> Device filter (TPS65986) -> Port filter (UFP)

2. The template file I selected is also attached herewith.

Note: I tried selecting DFP template files also but the error still persist

Please advice..

Thank You Brad, the template is now loading. But I am able to see the "Multi function preferred" bit checked by default and "UFPD Receptacle or DFPD pin assignment selected with C & D by default. Attached the screenshot herewith.

1. Does it mean I can use the same binary for my configuration ? Is there any other setting to be taken care for our application ?

2. How can I relate this with Configuration ID's ? At which config ID this mode will work ?

3. Do I need to change the PP_HV configuration ?

For your quick reference I am attaching the image of our application.

Hi Brad,

I tried generating the "Flash image binary file" through save binary option(refer figure 1 in attachment) using the templates fix shared to me. But when I try to flash the binary file using "TPS6598x Utilities GUI"  tool it fails in 1st step configuring test itself (refer figure 2 in attachment). It show again the Exception Encountered error. I followed the steps given in section 7 of TPS65986_EVM.pdf. However I have still listed below the step I have followed,

GENERATING BINARY FILE:

1.  Launched TPS6598x Application Customizer 2_12 tool

2.  Selected Project -> New project -> TPS65986 -> UFP -> TPS65986_HD3SS460_UFP_Full_2_10-fix.tpl. The project loaded showing default binary file (tps65981_2_6_v0001.11.09.bin) in General settings tab (Shown in figure 3)

3.  Selected Shared Device settings -> Display port capabilities -> verified Multi-function preferred bit enabled & UFP pin assignment with C & D selected (Shown in figure 4)

4.  Selected Binary -> Save binary -> given name for "Flash image binary save file name". Click Ok. (Shown in figure 5)

5.  Got the .bin file created in the specified location

FLASHING BINARY FILE:

1.  Launched TPS6598x Utilities GUI  tool

2.  Selected Configure -> USB to I2C/SPI Adapter -> Aardvark (Shown in figure 2)

3.  Click "Test Configuration Settings" .  Shown error " (figure 2)

Exception Encountered during Configure Test

Aardvark Interface loading Error: No module named aardvark_py"

Am I missing anything in the steps to be followed. Please correct me if  I am wrong in any steps. Do we need to use both the tools for this flashing ?

Note : The exception error shared last time was still present if select any other option in tool. Ex: If  I select "Import configuration from device"  the error will be shown.

With old version tool (TPS6598x App Customization Tool & TPS6598x Host Interface Tools), if you are able to flash the SPI flash as instructed in section 7 of TPS65986_EVM.pdf  then can you please share that setup files. Because right now I cannot verify even generated .bin file working or not. We wanted to test this as quick us possible. Your support would be very much helpful to solve this issue..

Thanks

Binary file generation & Flashing Error.zip

Hi Brad,

Hope you doing good..

As you mentioned I am are able to flash the bin file successfully.. But I am not able to see USB detection. The pendrive connection is not detected with the binary generated by me..I have attached the binary file generated by me for the 2-Lane USB & 2-Lane DP configuration. Can you please help us in checking the binary file ?

The flashing is done in two method as mentioned below:

1. Used TPS6598x utility GUI tool to flash the "Low region binary" file through I2C interface (As per section 3.1 of TPS6598x Application Customization tool user guide)

2. Used Aardvark Flash center tool to flash the "Full Flash image binary" file through SPI interface. (SPI flash chip is directly wired to Aardvark emulator, TPS6598x utility GUI tool is not used)

Note: Tired using TPS6598x utility GUI tool to flash the "Full Flash image binary" file through SPI interface but it shown the exception error as noted in my previous discussion

Kindly advice..

Hi Brad,

Attached the project file along with recent binary & our application concept for your reference. The template I am using for new project is the one shared by you named "TPS65986_HD3SS460_UFP_Full_2_10-fix.tpl". Since the default templates comes along with tool for TPS65986 is showing exception error.

The changes done are

1. Multifucntion preferred bit (0x51) -> enabled

2. UFP_D Pin Assignments Supported (0x51) -> Selected C & D

3. Port information (0x28) - > Sink/Source. Power Role = Sink. Data Role = UFP. PR_Swap supported, DR_Swap supported.

Thanks

Hi Brad,

Sorry for such delayed response..My thanks to you for sharing corrected project file.

The binary from this project file helped us to some extent. Right now with we are able to see the display instantly on power-up but goes off after 2 seconds. Later that there is no display image coming. When we probed on High Speed Mux(HD3SS460) select lines from GPIO's of TPS65986 chip it is in 4 lane DP state(AMSEL->H, POL->H/L, EN->H) as shown in attached image. So it looks like the configuration of 2 Lane DP + 2 Lane USB is not effected in the project or binary file we are testing now. Kindly help.

Hi Brad,

Sorry for sharing false data.. The High Speed Mux(HD3SS460) select lines(AMSEL->L, POL->H/L, EN->H) from GPIO's of TPS65986 chip is proper for 2 Lane DP + 2 Lane USB. But still the we are not seeing the DP signals.

I have doubt on HPD between Display & TPS65986. Felt like handshaking of Type C source device & DP sink is having issue during negotiation?

Expecting your suggestion or guidance on this. Please help..

Hi Pandiya,

I have been assigned to your issue and wanted let you know I am working on recreating it. I will update you asap.

Thanks

Hi Jeffrey,

Thank You for your response.

Awaiting for your updates..

Hi Pandiya,

While Iam still trying to recreate your issue I wanted to give you a guide on how to enter DP alt mode with the base EVM FW which will work with two tps65986 just to get you up and running with something.

Please, Let me know if you are able to enter DP mode using this guide attached below. I will update you asap reguarding your issue.

0638.Testing DP alt mode with base FW image.docx

Hi Jeffery,

Sorry for the delay in responding..

I have tested this setup already to make sure the boards are working with two tps65986. However the barrel jack is connected to Sink/UFP board only (Right side board) and it was working.

As per the document shared by you, When I connect the barrel jack on the source/DFP, the Sink/UFP board is not powering ON and no display & no USB working. So my understanding on the default firmware not working in this case is because when sink/UFP board is kept all dip switches to the left (all zero's), this configuration does not support power role of sink (as mentioned in Table 2. TPS65986EVM Configuration Table in TPS65986 EVM User's Guide).

To brief you about what is my expected firmware setting is please refer the attached picture. Awaiting for your response.

Hi Pandiya

Team has confirmed that DP Alternate mode is fully functional with TPS65986 EVM using EVM recovery firmware image as well as latest released v1.12 firmware image. You can follow Testing DP alt mode with base FW image document that Jeff has posted and let us know if there is any follow up question based on your tests.

Atiq

Hi Atiq,

We are able to test the same using 2 TPS65986 EVM and it is working. However our use-case is sink only with 2lane DP + USB3.0 as mentioned in my last reply. So I tried connecting the a TPS65986 EVM with sink settings to USB type C host (Mobile phone/Mac Mini) and the sink EVM is restarting continuously. Then if I connect barrel jack to this board, Display(hopefully 4 lane) & USB (hopefully USB2.0) both are working. This is making us to depend on external power in addition to USB power even in SINK only mode. Does it need hardware modification for grounding PP_5V0 & PP_Cable for unused condition?

Can you please test similar scenario with the default firmware and help in creating the custom firmware if needed to meet the our sink configurations ?

Query & observation on flashing the recovery firmware:

1. Why we need to use "tps65982_evm_flash_image.bin" for TPS65986 device
2. Yesterday evening after re-flashing "tps65982_evm_flash_image.bin", the ‘VERSION’ (0xf)  register says 0x01119 (Byte1 -> 9, Byte2 -> 11, Byte3 -> 1). Is this okay ? Please advice.

Thanks

Hi Pandiya,

The  "tps65982_evm_flash_image.bin" is supposed to say  "tps659826_evm_flash_image.bin", which is from a inconsistent test case. As for your 2 lanes of DP and USB3, the recovery FW mentioned above will not do 2 lanes (with any combination of dip switch config).  

The DP pin assignment needs to be 'D' (instead of 'C') in order to be in 2 lanes. I am updating the test document I previously sent which will allow you to enter 2 lane DP/USB3. I will upload when complete.   

note: In order to get pin assignment D, Multifunction Preferred has to be enabled however there are some connection issues with what I suspect to be from updated graphics driver.  

Thanks

Hi Pandiya,

The MX25V8035FZUI is not a supported flash type by 86 and could be incompatible. We recommend using Winbond - W25Q80JVNIQ to flash with the 86.How to flash SPI_86.docx

However I still included a troublshooting guide for your current test case.

Thanks

Hi Jeffery,

Ya it is working but there are some inconsistency issue so we are testing more understand the background of the issue. I will share my observations after completing our planned testing on it.

Particularly USB3.0 status is connected in TPS65986 data status register but the speed is always in USB2.0 only. Even the USB descriptor says the device detected is USB 2.0 or USB2.1. We are working on why USB3.0 controller connected to his bus is not advertised as USB3.0..Do you have any comments for this issue?

Thanks much
