TPS65987D: TPS65987+TPS55288

Hi Allen,

You should see this app note for the I2C Master settings: https://www.ti.com/lit/an/slvae18/slvae18.pdf

From your project file, it looks like there are no I2C Master Events inputted, you can see these by, clicking Settings --> Show I2C Master Events Table. You will need to input the data you would like the PD controller to send to the other device.

Also, in 0x62, I noticed that you put in number of indices and start index under Port 1, please move these to "Common."

Thank you,

Hari

power sink, is there documents that has example of setting up power sink? use apple macbook power supply to extract 20v power? (or any other rail?)  i dont think i did it right, here is updated config file

Hi Allen,

Yes it looks like you have both ports configured for I2C master and also on Port Control register you have chosen to initiate/process source capabilities but will need to change to sink if you would like the PD controller to be just sink only. 

Also, is this the updated project file? I still don't see any I2C Master Events inputted.

I would recommend watching these tutorials on the product page to help configure the device: https://training.ti.com/how-evaluate-and-configure-our-usb-type-c-pd-controllers

Thank you,

1) i need to do both sink and source
2) where/i dont see  I2C Master Events in the program?
3) where is the GUI PD log in the program?

Hi Allen,

To do both, you will need to select both process swap to source and sink and deselect both the Initiate swap for source and sink.

I mentioned in my previous reply for the I2C Master Events, you will need to go to Settings --> Show I2C Master Events Table.

I'm not sure I understand your last question, are you asking how you can capture PD logs? If so, you will need a PD analyzer such as one from Total Phase.

Thank you,

Hari

-> there is no "Show I2C Master Events Table", there is only "Show I2C Control Events Table"

-> you will need to select both process swap to source and sink and deselect both the Initiate swap for source and sink.

is this correct?

here is the updated config file with change

related question, i am using

USB-C-PD-DUO-EVM Evaluation board

for testing, 

i am connecting the source to sink directly with type-c cable and apply power supply to the sink board, however,  the sink 9v 15v 20v button does not respond, does that mean there is issue with onboard (sink) firmware? if so, can i have the default firmware to relish it? 

only place i found in the application is :

also i already split the USB-C-PD-DUO-EVM to 2 separate board, and in order to flash sink board, i stack on top of each other and set jumper to SNK


however, if i use the following: Device > Re-Flash EVM Firmware (Recovery) > and select "tps65987_power_duo_mode_SINK_EVM_flash_image.bin" i get error/SPI error, eventho the setting shows SPI is working fine
