I cannot find any documentation on GPIO mapping for the GNE2 board.
Specifically, if I want to switch the I2C lines through to the headers.
To do that I need to drive the AMUX1_IN line, in order to switch the MUX from 0 to 1, thus switching the I2C lines through to the header.
The schamtic shows that AMUX1_IN comes from U2/EXP2 on page 20.
But I cannot find any data that shows how to map the I/O lines from "EXP2" to GPIO numbers as required by the linux file system at :
/sys/class/gpio/export
For the GEN1 board there is an IO Mapping document, but it was last updated in February so does not cover GEN2.
Anyone got any documentation on GEN2 IO Mapping?
