TPS65987DDJ: Applying Patch bundle through I2C from Host

Good Afternoon Srini,

I will review your setup and provide an update by EOB on 5/4.

Kind regards,

Conner Gillette

Please follow the attached steps and let me know if you run into any further errors.

Hi Conner Gillette,

Thanks for the presentation. 

We will test and let you know the results by tomorrow.

Thanks 

Srini

Thank you Srini. 

Hi Conner Gillette,

Please clarify the following:

1. Is above attached PPT for flashing patch bundle to external EEPROM(I2C)?
2. We have only SPI flash connected to TPS65987D we don't use external I2C EEProm 
3. Can you please share the procedure to load the Patch bundle to External SPI flash over Host I2C and to Load to internal SRAM over Host I2C? 
4. We are following: /cfs-file/__key/communityserver-discussions-components-files/196/5100.SPI_5F00_Less_5F00_EC_5F00_Based_5F00_Host_5F00_Programming_5F00_Over_5F00_I2C_5F00_slva972a.pdf
5. We are following this reference for Register set: TPS65987DDH and TPS65988DH Host Interface Technical Reference Manual (Rev. B)
6. There is no Commands like Go2P, PBMs, PBMc in above refernce manual, But those commands gets successful response, Can you please share exact reference Manual for Chip we are using (TPS65987DDJ)?

Thanks 

Srini

Hi Conner Gillette,

Please find the attached Schematic for your reference

We have only SPI flash connected to TPS65987D, we are following below reference for flashing patch bundle to SPI flash 

TPS65982 FW Update from Embedded Controller Over I2C (Rev. A) (ti.com)

1. Bootflag reg (0X2D) status responses 0xF8 (Region1Invalid - 1, Region0Invalid - 1, Region1 - 1, Region0 - 1)
2. Region0 and 1 seems invalid and attempted.
3. Flrr commands response with random Region address at every run.
4. FLem and FLad commands are getting successful responses.
5. FLwd command also successful while writing patch data.
6. FLvy command responses 0x01 (Invalid patch/configuration)

Are we missing anything? Kindly suggest us the proper way of programming SPI flash over Host I2C. Any sample application code will be more helpful.

Regards,

Srini

Could you provide your project file from the GUI? It looks like there might be an issue with your project file.

Hi Conner Gillette, 

Please find attached Project file and exported Low region array from Project.

Why Initial boot flag status shows invalid regions even before starting the patch bundle command process?

Hi Conner Gillette,

Our requirements for TPS65987DDJ:

1. USB 3.1 UFP 
2. VBUS sink in Both PPHV (20V/3A)
3. Display Port ALT mode enabled. 
4. GPIO 0 --> Orientation Event
5. GPIO 1 --> DP port Event
6. GPIO 2 --> USB Event
7. GPIO 3 --> HPD Event

Can you please provide Project file for above mentioned configuration? 

Regards

Srini

Thank you for providing the project file. I will review all of the provided information and provide on update on the 10th.

My apologies for the previous misunderstanding. You can ignore the PBM document.

Are you organizing the binary into the flash as shown in Figures 1 and 2 of document slva783a? This is likely the reason that Region0 and Region1 are reading as invalid.

There is also sample code for programming the TPS65987 over I2C using the SPI flash in section 4 of slva783a.

Kind regards,

Conner Gillette
