3.1.3 I2C1 Hardware Connection Using the TPS26744EQ1EVM

The TPS26744EQ1EVM can also provide the required USB to I2C1 interface for programming the integrated flash memory using the TPS267xx-Q1-GUI. The onboard Raspberry Pi RP2040 uses a logic level of 3.3V. The TPS26744EQ1EVM connects through USB from the J12 Type-B receptacle to the PC. Make sure that the J5 jumpers shorting the I2C path to the onboard TPS26744E-Q1 device are removed. On the product being programmed, the relevant TPS2674x-Q1 pins must be brought out for physical contact with the EVM (such as male headers or test pads), and must be driven by no other source while programming.
