4.1.1.2 Control Card Settings
Certain settings on the device control card are needed to communicate over JTAG; use the isolated UART port, and provide a correct ADC reference voltage. The following settings are required on revision 1.1 of the TMS320F28377D control card. Refer to the info sheet located inside C2000Ware at <sdk_install_path>c2000Ware\boards\controlCARDs\TMDSCNCD28377D.
- Set A:SW1 on both ends of the control card to the ON (up) position to enable the JTAG connection to the device and UART connection for the SFRA GUI. If the switch is OFF (down), the user cannot use the isolated JTAG built in the control card, nor can the SFRA GUI communicate with the device.
- Connect the USB cable to A:J1 to communicate to the device from a host PC on which Code Composer Studio™ (CCS) runs.
- For the control loop, set the appropriate jumpers to provide a 3.3-V reference externally to the on-chip ADC.
Certain settings on the device control card are required to communicate over JTAG and use the isolated UART port. The user must also provide a correct ADC reference voltage. The following settings are required for revision A of the TMS320F280049C control card (refer to the info sheet located at <sdk_install_path>\c2000ware\boards\controlcards\TMDSCNCD280049C:
- Set both ends of S1:A on the control card to ON (up) position to enable JTAG connection to the device and UART connection for SFRA GUI. If this switch is OFF (down), the user cannot use the isolated JTAG built in on the control card, nor can the SFRA GUI communicate with the device.
- Connect the USB cable to J1:A to communicate with the device from a host PC on which CCS runs.
- For the control loop, use the internal reference of the TMS320F28004x and move the S8 switch to the left (that is, pointing to VREFHI).
- For the best performance of this reference design, remove the capacitor connected between the isolated grounds on the control card, C26:A.
- GPIO24 through GPIO27 are muxed on the TMS320F280049C control card. To route them to the correct control card pins for the SDFM, put all the switches on SW5 to OFF (down) and all the switches on SW6 to ON (up).
