Other Parts Discussed in Thread: TPS65987D
Hi Expert,
Good day.
I designed a board with the TPS65987D USB-C PD controller. The controller is working fine and the design as well. I am now trying to program the TPS65987D with the desired USB-C PD profiles. To do it I am using the Application Customization Tool you provide on your website. I am using a brand new TM4C123GXL board to connect the SPI and I2C signals to the USB-C board.
However, the PC recognizes the TM4C123GXL board as a Stellaris In-Circuit Debug Interface and assigns it to a virtual COM (example COM1). When I open the Application Customization Tool software it is able to recognize the TIVA C on COM1. If I press Test COM by reading the TIVA FW version it remains unknown.
Anyway, I press OK, and then if I go on Sweep address range for device response it will stuck for a lot of time and I have to close the application tool (In both cases, be the USB-C controller powered by USB power supply or not).
If I press I2C HI Read I get the error Unable to open the COM port, then I suppose it is a problem with the software. I already installed the TI drivers for TIVA-C, did I install the wrong ones?
What am I doing wrong?
Also, the address of the I2C_1 port of the TPS65987D is tied to GND, then it is 0x00 according to the datasheet.
Please advise
Regards,
Josel
