Page 16: Storage Interface
UART/RS-232/RS-485 RS-232 and RS-485 standards are supported on the ConnectCore MP13 Development Board, by sharing one CPU UART port (UART7). This means that only one of the two protocols can be use at a time. Selection between both is done through three three-position headers (J15, J16 and J17). -

Electrical specification Supply voltages The ConnectCore MP13 Development Board has three supply inputs. Two of them power the whole system (ConnectCore MP13 Development Board plus the ConnectCore MP13 system-on-module) and the other one powers the RTC of the module when the main supply is not present. The following table... -
Page 22: Appendix A - Eth2 Interface Correction
The strategy Digi follows to clock the 10/100 MB PHY is to use a TTL clock from the MAC (CPU), instead of using an external crystal. The PHY input pin for the reference clock is XTAL1/CLKIN (pin 5). This pin is currently connected to pad D11 of the SOM, which corresponds to thePH11 pin of the CPU. -

0-ohm resistor (R283) to SPI4_IRQ_N. That is why the net changes its name. Figure 6. Multiplexing options of CPU pin PA11, where ETH2_CLK output reference clock for 10/100 MB PHY is available (AF13). To fix this connection, follow these steps: ConnectCore MP13 Development Board... - Page 24 Appendix A - ETH2 Interface Correction Solution - Depopulate R283. - Depopulate R298. - Wire a cable from CPU pad side of R283 to PHY pad side of R298.
