Flash Programming Modes
The following table shows the methods you can use to program the configuration bitstream into the flash device on your board. Although you can program the flash directly using the SPI interface, this method requires that you have a SPI header on your board or use an FDTI chip. Therefore, Efinix recommends that you use a JTAG bridge, because that method only requires a JTAG header, which you would typically have on your board for other purposes anyway.
Important: If you are using the secutiry feature (Titanium or Topaz only), you can no longer use the JTAG bridge
flash programming modes after you disable JTAG access. Refer to Securing Titanium Bitstreams for details.
| Mode | Description |
|---|---|
| SPI Active (serial/parallel) | Use the Efinity Programmer and a cable connected to a SPI header on the board. |
| SPI Active using JTAG Bridge (New) | A improved version of the SPI Active using JTAG Bridge (Legacy) mode with a faster flash programming time. |
| SPI Active x8 using JTAG Bridge (New) | A improved version of the SPI Active x8 using JTAG Bridge (Legacy) mode with a faster flash programming time. |
Notice: Refer to Program using a JTAG Bridge
