4.1.2 TIDA-010979 Hardware Setting

To enable the TIDA-010979 board, apply DC voltage 48V (or lower voltage depending on motor rating) between DC+ and DC– through holes. Connect the three motor phase power cables to PHA, PHB, and PHC through holes.

J1 serves as the JTAG connector for software code debugging. Connect the XDS110 JTAG Debug Probe to J1. J2 serves as the UART connector and can also connect to the XDS110 AUX pins to print information on terminal or transmit data such as writing the flash through UART communications.

J3 serves as the boot mode selection jumper. With J3 shorted, the OPSI (4S) – Quad Read mode is enabled as the MCU boot mode. With J3 opened, the UART mode is enabled as the MCU boot mode. For more information regarding AM2612 boot mode, see also the EVM setup in the AM261x MCU+ SDK 11.01.00 user guide.

J6 serves as the connector for encoder 1 to provide feedback for the position information of motor rotator while J7 serves as the connector for encoder 2 to provide feedback for the position information of the gearbox reducer. J4 and J5 serve as Ethernet connectors that can function as one port IN and one port OUT for daisy chain applications. Figure 4-3 shows the TIDA-010979 hardware setup overview.
