2.4.6 USB Connectors (J8, J10)

Note:

The EVM must be powered on before the USB cables are connected. Plugging in the USB cables before powering on the board can cause the board to get stuck in a permanent reset state. In the event that this occurs, just unplug the USB cables, power cycle the EVM, and plug in the USB cables to resolve the issue.

The AWR2944EVM/AWR2944PEVM has two standard micro USB connectors.

Micro USB Connector J10 provides access to the AWR2944 UART, SPI, I2C, RS232, and SOP interfaces through the FTDI chip.

Micro USB connector J8 provides access to the JTAG, MSS_UARTA, and MSS_UARTB interfaces of the AWR2944 via the XDS110 emulator.

This is the UART interface used to flash the binary to the onboard serial flash and for Out-of-box (OOB) demo.

Note: The OOB demo requires only J8 to be connected to the PC. J10 is not used for the OOB demo.
