2.5. Installing the Intel® FPGA Download Cable Driver

The development board includes integrated Intel® FPGA Download Cable circuitry for FPGA programming. However, for the host computer and board to communicate, you must install the on-board Intel® FPGA Download Cable II driver on the host computer.

Installation instructions for the on-board Intel® FPGA Download Cable II driver for your operating system are available on the Intel website. On the Cable and Adapter Drivers Information page of the Intel website, locate the table entry for your configuration and click the link to access the instructions.

The on-board Intel® FPGA Download Cable II circuit defaults to 24M and can be unstable depending on the bus loading or HSMC cards installed. It is recommended to change the speed down to 16M for better stability.

From a Nios® II Command Shell, type the following


Note: returns the device lists of all the USB cables

jtagconfig --getparam <cable> Jtagclock

Note: returns current setting

jtagconfig --setparam <cable> JtagClock 16M

Note: sets to 16M (recommended)
Attention: <cable> is the index of the USB cables and it starts with 1.
Attention: This setting is non-volatile and may need to be done if you power down and unplug your board and then power it back up and plug it in again.
