Part Number: TPS25750
Other Parts Discussed in Thread: , TPS25751EVM

Tool/software:

Hi, How can I connect external circuit to the TPS25750EVM via I2C for programing? Can I disconnect the internal TPS25750?

    Hi Schroedinger, 

    Thank you for reaching out!

    What is the method of programming (i.e. flash via EEPROM or load configuration via MCU/EC)?

    Best Regards,

    HI,

    We have to decide between 2 options: 

    1) for development I want to program my design via the EVM (if possible) as it seems easy. So, for me, the best way would be to connect my design to the EVM (I2C-bus). May be I could use a diffenrent I2C adress than the EVM for programming my TPS25750 when both TPS25750 are in parallel? I am not sure it s possible for the interent based progrmaming tool. 

    2) later in production I could do programming through the MCU or programing the EPROM (copying the EPROM content). 

    I found a publication here how to do it via the MCU. If there is a more detailed description of the MCU programming it would be helpful. 

    Best regards

    Karl

    Hi, 

    1) See my suggestion below but please note that this has not been tested. 

    You may be able to remove jumper J16 to isolate the EEPROM on the TPS25751EVM from the PD controller and connect your design via I2Cc. Keep in mind that the EEPROM is also connected to LDO_3V3 and other resistors (a breadboard may be helpful to make these connections). 

    Assuming this works as intended, you would then connect the TIVA on the TPS25751EVM to the GUI tool to flash your board. 

    Another suggestion would be to use an AARDVARK to flash your board (assuming there is an EEPROM on there)

    2) Refer to Chapter 5 in the Technical Reference Manual on how to load a patch bundle over I2Ct via MCU. 

    Best Regards,
