2 Jumper Settings
The ARM Cortex-M1-enabled IGLOO development kit comes with the following default jumper
settings.
| Jumper | Development Kit Function | Factory Default |
|---|---|---|
| JP1 | Provides 3.3V to Prog. USB interface | Installed |
| JP2 | Provides 2.5V to FlashPro3 FPGA | Installed |
| JP3 | Provides 1.2V and/or 1.5V core voltage to IGLOO® FPGA | Installed 2–3 |
| JP4 | Provides 3.3V to FlashPro3 FPGA | Installed |
| JP5 | Selects 1.2V and/or 1.5V core voltage for IGLOO FPGA | Depends on whether FPGA is V2 or V5. V2: Installed 2–3. V5: Not installed (Auto Switch mode) |
| JP6 | Connects 3.3V to Pin 2 of P1 connector | Installed |
| JP7 | Connects VIN (5V) to Pin 1 of P1 connector | Installed |
| JP8 | Connects push button reset to P3 | Not installed |
| JP9 | Connects 3.3V to VPUMP pin on FPGA | Installed 2–3 |
| JP10 | Connects 2.5V to Pin 2 of P2 connector | Installed |
| JP11 | Connects RS232_TX signal from FPGA to RXD input of Serial-to-USB chip | Installed |
| JP12 | Connects RS232_RX signal from FPGA to TXD input of Serial-to-USB chip | Installed |
| JP13 | Connects 3.3V to Bank 3 of IGLOO FPGA | Installed 2–3 |
| JP14 | Connects VIN (5V) to Pin 1 of P2 connector | Installed |
| JP15 | Provides 3.3V to non-FlashPro3 portion of board | Installed |
| JP16 | Connects 3.3V to Bank 0 of IGLOO FPGA | Installed 2–3 |
| JP17 | Connects 2.5V to Bank 1 of IGLOO FPGA | Installed 2–3 |
| JP18 | Connects 3.3V to Bank 2 of IGLOO FPGA | Current is measured at this point |
| JP19 | Connects 3.3V to IGLOO FPGA | Current is measured at this point |
| JP20 | Supplies voltage to PLL | 1–2 connects core voltage to PLL 2–3 shorts VCCPLF to GND to disable PLL and insure it does not consume power |
| JP21 | Selects source of Flash*Freeze pin. | 1–2 connects GPIOB_0 to FF Pin. 2–3 connects push button circuit with RC and Schmitt trigger buffer |
| JP22 | Selects input power (5V) to the main board logic | Factory installed between Pins 1 and 4 to select power from 2.1 mm external power supply connector. Other jumper positions have been removed and are no longer supported |
| JP23 | Connects VIIN (5V) to Pin 1 of P5 connector | Current is measured at this point |
| JP24 | Connects 3.3V to Pin 2 of P5 connector | Current is measured at this point |
