Programming

The IGLOO2 device can be programmed through the JTAG interface.
programming.
FLASH_GOLDEN_N
IGLOO2 FPGA
JTAG_SEL: JTAG_SEL is used to switch between FP4 header (High) and RVI header or ETM header (Low).
For more information on J8 jumper, refer to
RVI Header
One 10X2 RVI header is provided on the board for debugging. This header allows plugging in the Keil ULINK
debugger or IAR J-Link debugger.
FlashPro4 Programming Header
The IGLOO2 device on the Evaluation Kit can be programmed using a FlashPro4 programmer. In addition, FlashPro4
is used for software debugging by SoftConsole.

FTDI Interface

FT4232H chip features are listed below:
•
USB 2.0 high speed (480 Mbps) to UART/MPSSE IC
•
Single-chip USB to quad serial ports with a variety of configurations
•
Entire USB protocol handled on the chip. USB specific firmware programming is not required
•
USB 2.0 high speed (480 Mbps) and Full Speed (12 Mbps) compatible
•
Two MPSSE on channel A and channel B, to simplify synchronous serial protocol (USB to JTAG, I2C, SPI,
or bit-bang) design
•
Fully assisted hardware or X-On/X-Off software handshaking
