I have to configure I2S3_SCLK, I2S3_DOUT, I2S3_DIN, and I2S3_FS as GPIO inputs on a 3rd party carrier board. I’ve never done anything like this and I’m quite confused by the documentation. I have the following questions:
- From the pinmux configuration template I can find the pin #, however, I’m not sure how to identify the MPIO Pad Type (ST, CZ, DD, LV_CZ). I tried searching the TRM and the datasheet to no avail;
- Do I have to change the .cfg file on the host and re-flash the board (as shown in this example on eLinux), or can I work directly on the device (which is, as far as I understand, what
jetson-iodoes for the DevKit)?
- From what I understand from section 22.214.171.124 PinMux programming in the TRM, it looks like that the function of certain pins can be changed programmatically on the fly. Is that an alternative to changing the static PinMux configuration?
