SL2610 RDK

Connection Steps

1. Power Connection

• Connect a 5V USB Type-C power adapter to the PWR IN connector.

• Ensure the power adapter can supply sufficient current (recommended: 2A or higher).

• Power LED should illuminate when connected.

2. Data Connection

• Connect the USB 2.0 OTG port to your host machine using a USB-C cable.

• This connection is used for:

  • eMMC flashing

  • System Manager image installation

3. UART Logging Connection

For console output and debugging logs, connect a USB-to-UART adapter:

Signal	Board Pin	Description	Notes
UART TX	Pin 8	SM_UART0_TX	Board transmit → Host receive
UART RX	Pin 28	SM_UART0_RX	Board receive → Host transmit
GND	Pin 6	Ground	Common ground reference

UART Settings:

• Baud rate: 115200

• Data bits: 8

• Parity: None

• Stop bits: 1

• Flow control: None

│     RX      │ ←───────────── │  Pin 8   │ (TX)
│     TX      │ ───────────→   │  Pin 28  │ (RX)
│     GND     │ ←────────────→ │  Pin 6   │ (GND)
└─────────────┘               └──────────┘

Verify Hardware Setup

1. Check power LED is illuminated.

2. Verify USB 2.0 OTG connection shows up on host:

   • Windows: Device Manager

   • Linux: lsusb should show USB device

   • macOS: System Information → USB

3. Test UART connection using a serial terminal:

   • Open serial monitor (115200 baud, 8N1)

   • Reset board

   • Bootloader or system messages should appear

Enter USB Boot Mode

Use USB boot mode for flashing via the USB boot tool:

1. Press and hold USB_BOOT

2. Press and release RESET

3. Release USB_BOOT

The board will enumerate over USB for flashing operations.
