4.1 Hardware Setup

Follow these steps to setup the EVM before launching the GUI:

  1. TI recommends making any jumper configuration changes prior to powering the EVM. The hardware device variant latches MODE, SLEW RATE, and DIAG jumper settings after power-up and coming out of sleep (however, ITRIP takes effect immediately).

    For the SPI device variant, TI recommends making the IPROPI selection before powering the EVM.

  2. Connect micro-USB cable to J6 (Figure 2-3). The digital portion of the EVM becomes active. LEDs D6 and D7 illuminate. The nFAULT LED D2 can blink at a fast rate to indicate the absence of a VM power supply. For proper GUI application operation, connecting the EVM USB cable to a computer before applying +BAT power to the EVM is important. For standalone EVM testing, a USB connection is not necessary.
  3. With the +BAT external supply outputs disabled, connect +BAT supply to the screw terminals on the EVM (J14), observing polarity (Figure 2-4).
  4. Energize the +BAT supply. VM LED D3 illuminates. If the VM LED does not illuminate, then verify polarity and check fuses are installed and have continuity. Power consumption is on the order of 10mA @ +12VDC input. Significantly higher or lower can indicate a hardware problem if the fuse and supply polarity are correct.
  5. The EVM is ready to be used with the GUI application ( Section 4.2). In certain situations, such as while disconnecting and reconnecting VM power before the power supply capacitors are fully discharged a proper firmware reset does not happen. A proper reset is indicated by the STATUS LED D1 blinking at a rate of approximately 1Hz for the SPI variant EVMs and approximately 0.1Hz for the HW variant EVMs. If the Status LED is not blinking as expected, then press the reset push button once with jumper J1 installed in the RST position. Do not unplug the USB cable while the VM power is active. If the USB cable is unplugged, then switch off the VM power, wait until the power is fully discharged, and proceed to step 2.
  6. The latest version of the GUI application is bundled with the latest version of the EVM firmware. TI recommends to do a firmware update before selecting and connecting to an EVM variant using the GUI application. The firmware update procedure is described in Section 4.3.4.
