I am using Jetson nano module with a custom built carrier board.
The existing SPI pins are already used, will we be able to software emulate the SPI on the I2S pins located on the Jetson? Currently these pins are not being used in the current schematic. The pins numbers are as follows
Pin 220 - I2S1_DOUT
Pin 222 - I2S1_DIN
Pin 224 - I2S_FS
Pin 226 - I2S_SCLK
The datasheet says that these pins are used for streaming audio data between system memory and audio codec. Will there be any conflict if we utilize these pins for emulating SPI? Please advise.
