Configuration Options

The FPGA on the SP601 Evaluation Board can be configured by the following methods:

•“3. SPI x4 Flash,” page 18

•“4. Linear Flash BPI,” page 20

•“JTAG Configuration,” page 42

For more information, refer to the Spartan-6 FPGA Configuration User Guide. [Ref 2]

Table 1-23:Mode Pin Settings (M2 = 0)

Mode Pins (M1, M0)	Configuration Mode

00	Master Byte Peripheral Interface (BPI)

01	Master SPI x1, x2, or x4

10	Not implemented on SP601

11	Not implemented on SP601

JTAG Configuration

JTAG configuration is provided through onboard USB-to-JTAG configuration logic where a computer host accesses the SP601 JTAG chain through a Type-A (computer host side) to Type-Mini-B (SP601 side) USB cable.

The JTAG chain of the board is illustrated in Figure 1-31. JTAG configuration is allowable at any time under any mode pin setting. JTAG initiated configuration takes priority over the mode pin settings.

FMC bypass jumper J4 must be connected between pins 1-2 for JTAG access to the FPGA on the basic SP601 board, as shown in Figure 1-31. When the VITA 57.1 FMC expansion connector is populated with an expansion module that has a JTAG chain, then jumper J4 must be set to connect pins 2-3 in order to include the FMC expansion module's JTAG chain in the main SP601 JTAG chain.
