The EagleCore SOM Carrier is configured to use power from DC power supply by connecting it to the 

External DC Jack (J1). The external power supply should be in the range of +12V 5A.

The Power Switch (SW1)is used to switch on/off the board. Sliding it to ON to supply power to the board from External DC Jack. Sliding it to OFF to power off the board.

The EagleCore SOM Carrier has a power LED (D4) that will illuminate when the board receives sufficient power during startup.

The EagleCore SOM Carrier have push button switch (SW2) for resetting the entire system. This pin is connected to the system reset pin of the FPGA.

The EagleCore SOM Carrier includes a dedicated switch (S1)for PROGB functionality, which is connected to the corresponding PROGB pin on the FPGA.

The EagleCore SOM Carrier supports 2 Gigabit ethernet communication lanes (J2 & J3)which support 10/100/1000Mbps Ethernet interface. The FPGA pins can be connected to ethernet Rj45 jack and supports both RGMII and SGMII standards depending on the FPGA configuration. The EagleCore ZU-Plus MPSoC SOM supports only one Ethernet connection, which is provided through the RJ45 jack “J3”. It also has an additional Activity and Link LED for providing visual indication for the user about the status of the ethernet. The Ethernet LINK LED indicates the presence of a network connection when illuminated, while the Gigabit Ethernet ACTIVITY LED signals active data transmission or reception over the network.

The onboard USB connector (P15) helps a PC/Linux/Mac computer to communicate with this module. 

Use a USB type C cable to connect with a PC. This port will act as both JTAG and UART interface.

The EagleCore SOM Carrier provide USB 2.0 OTG interface (P8) and can be accessed using Micro-B 

connector. USB OTG supports both Host, Device and OTG mode based on the configuration made in USB ID pin. A LED (D9) is connected with the USB_5V as an indication for the presence of the VBUS in USB pin.

The EagleCore SOM Carrier supports a microSD card slot (P12), offering additional non-volatile 

memory storage capacity. It operates in 3.3V and offer a compact and removable storage solution, making them ideal for storing data that exceeds the internal memory capacity of the FPGA. FPGAs can use microSD cards to store boot images or configuration data, which are loaded into the FPGA at startup.

EagleCore SOM Carrier have DIP switches (SW8) for changing boot configuration of the FPGA based on required functionality. Users can utilize all four pins or only the necessary ones, leaving the remaining MODE pins unconnected.

EagleCore ZU-Plus SOM

The boot configuration of the EagleCore ZU+ SOM will be based on the below configuration of switches:

The EagleCore SOM Carrier has a Coin Cell Holder (BT1) to support 1.8V coin cell that will support 

backup voltage for RTC when main power supply is off. RTC maintains accurate timekeeping through these battery-backup. The battery should be kept in the carrier board for providing voltage if the main power is off.

The EagleCore SOM Carrier has 2 CAN (P14)headers dedicated for CAN communication interfaces.

EagleCore SoC Carrier supports PMIC connector for programming the power section of the FPGA using I2C communication protocol (P10). It also includes a dedicated enable switch (SW3)to assist users in initially programming the PMIC.

EagleCore SOM Carrier supports two standard JTAG Header for programming and debugging purposes. JTAG 1 is compatible for Microchip and JTAG 2 is compatible for AMD. The JTAG signals from FPGA are shared between JTAG header and FMC connector.

JTAG 1 – Microchip (P13)

JTAG 2 – AMD (P23)

EagleCore SOM Carrier provide 9 user defined LEDs.

The EagleCore SOM Carrier has 2 dedicated switches (SW5 & SW6) for user defined purpose.

The EagleCore SOM Carrier supports both JTAG and FTDI programming for AMD FPGA boards. The configuration can be changes using  PGM_SEL switch (SW4). By default, switch SW4 is in the ON position for JTAG programming configuration. When switched to the OFF position, it will configure the board for FTDI programming.

The EagleCore SOM Carrier provides an additional 100 MHz LVDS oscillator for user defined purposes.

The EagleCore SOM Carrier has a dedicated lines for MIPI CSI-2 connector (P24). MIPI CSI-2 is a standard interface for connecting cameras to FPGAs, enabling high-speed, efficient, and scalable image and video data transmission.

The EagleCore SOM Carrier have dedicated header (P17) for differential analog input.

The EagleCore SOM Carrier supports 3 SMA connectors for differential transceiver clocks. Users can 

utilize this connector to meet additional transceiver clock requirements.

JTAG chain can be modified using jumper P16 near JTAG header. Following diagram shows JTAG chain configuration:

The EagleCore SOM Carrier has automatic FMC detection using the PRSNT_M2C_L signal from FMC. Normally, when an FMC board is not connected, the onboard circuitry will automatically close the JTAG chain keeping FMC out from the chain, so no user intervention is required. But, still, jumper P16 has been provided as a redundant back up to close the JTAG chain in case the automatic circuitry doesn’t work due to non-compliant FMC modules connected to EagleCore, or any or unforeseen reasons.

EagleCore SOM Carrier features a high speed, high pin-count FMC connector which can be used to provide additional features and capabilities to it using custom or commercial-off-the-shelf daughter boards. Apart from IOs, 8 GTX lanes are available via FMC connector for custom purposes.
