We wanted to Interface I2S, I2C, and GPIO1 Between FPGA Board EVM.
Suggests that I2S traces must be cut in order to test I2S.
Instead, can we Unplug USB and Provide all powers( 5v, 3.3v, and 1.8v) along with I2S, I2C, and other required lines. Would this work?
Is there any other approach to control I2S via an external Controller, without damaging the board (cutting traces)?
