USB-PD-CHG-EVM-01: Should I power the board before flash the EEPROM with Aardvark tool set

diverger

Part Number: USB-PD-CHG-EVM-01
Other Parts Discussed in Thread: TPS25750

Hi,

From other post, I learn that I should power the board first then flash it with Aardvark tool. But the datasheet says the master I2C on TPS25750 doesn't support multiple master, if we power the board before flashing, won't there be two I2C masters on the bus?

Thanks.

Hello,

Please see the following FAQ:https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1021134/faq-how-do-i-configure-the-tps25750-and-flash-the-eeprom-with-the-output-binary-for-the-board-usb-pd-chg-evm-01

If there is no PD communication, there will not be a multi-master because the TPS25750 will not be using the bus. Power the battery connection of the board and that should be enough.

Regards,

Mike Emanuel
