In TIDA-01627, If the TPS65987D is going to be the I2C master for the BQ25703A, then all I2C writes must be configured in the Application Customization Tool and loaded onto the TPS65987D from the SPI Flash during boot up. The I2C master writes in the TPS65987D cannot be changed during run-time. So, in TIDA-01627, if we need OTG, must have SPI Flash?
