Special Expansion Headers
There are several headers with additional signals for testing and debugging
purposes. Please refer to the next chapter for a extended list. ST7 and ST30 are
fixed function expansions and provide the IEEE1588 sigals of the ethernet
subsystem for external usage, as well as an additional UART on ST30.
For detailed signal description refer to connector pin list and LX2160A user
manual.
6.16.1 ST7 IEEE 1588 Signals
If SW6-1 is closed, RGMII2 signals from the MPX-LX2160 SoM act as IEEE1588
signals.
All ST7 signals are 3V3 level.
