5.2 Control Card Settings

Certain setting on the device control card are needed to communicate over JTAG and use the isolated UART port. The settings also provide a correct ADC reference voltage. The following are the settings required on revision 1.1 of the F28388D control card. Refer to the information sheet located inside C2000Ware at

<sdk_install_path>\c2000ware\boards\controlCARDs\TMDSCNCD28388D:

1. S1:A on the control card must be set on both ends to ON position to enable JTAG connection to the device and the UART connection for SFRA GUI. If this switch is OFF, one cannot use the isolated JTAG built in on the control card nor can SFRA GUI communicate to the device.
2. J1:A is the connector for the USB cable that is used to communicate to the device from a host PC on which Code Composer Studio (CCS) runs.
3. Based on the TMDSCNCD28388D_user_guide inside C2000ware, below debug mode using CCS and the onCard xds100v2 emulator, S2 is suggested to set in this way to put the C2000 device into WaitMode which can reduce the risk of connectivity issues: Position 1: OFF, Position 2: ON.
4. A 3.3-V reference is desired for the control loop tuning on this design; therefore, set the appropriate jumpers to provide a 3.3-V reference externally to the on-chip ADC. For version 1.3 of the F28388D control card, this means S3 and S4 are moved to the end with "." that is, to the left, which puts 3.3-V VDDA as the reference for the ADC. Refer to the information sheet for more information.

Certain setting on the device control card are needed to communicate over JTAG and use the isolated UART port. The settings also provide a correct ADC reference voltage. The following are the settings required on revision 1.1 of the F28379D control card. Refer to the information sheet located inside C2000Ware at

<sdk_install_path>\c2000ware\boards\controlCARDs\TMDSCNCD28379D:

1. A:SW1 on the control card must be set on both ends to ON (up) position to enable JTAG connection to the device and the UART connection for SFRA GUI. If this switch is OFF (down), one cannot use the isolated JTAG built in on the control card nor can SFRA GUI communicate to the device.
2. A:J1 is the connector for the USB cable that is used to communicate to the device from a host PC on which Code Composer Studio (CCS) runs.
3. A 3.3-V reference is desired for the control loop tuning on this design; therefore, set the appropriate jumpers to provide a 3.3-V reference externally to the on-chip ADC. For version 1.3 of the F28379D control card, this means SW3 and SW2 are moved to the end with "." that is, to the left, which puts 3.3-V VDDA as the reference for the ADC. Refer to the information sheet for more information.

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.

1. 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.
2. Connect the USB cable to J1:A to communicate with the device from a host PC on which CCS runs.
3. For the control loop, use the internal reference of the TMS320F28004x and move the S8 switch to the left (that is, pointing to VREFHI).
4. For the best performance of this reference design, remove the capacitor connected between the isolated grounds on the control card, C26:A.
5. GPIO24 through GPIO27 are muxed on the TMS320F280049C control card. Put all the switches on SW5 to OFF (up) and all the switches on SW6 to ON (up).
