(Original statement) How to Determine "error: more than one programming cable found in available hardware list-use-l

Abstract
Many people in the use of nios2-configure-sof *. Sof into the de2 or DE2-70, will encounter the above response, this paper proposes a solution.

Introduction
On de2, how does one install the μClinux operating system on de2? (IC design) (de2) (nio ii) (OS) (Linux) (centos) (μ Clinux), and then you must use the nios2-configure-sof under command prompt to change *. sof then enters de2/DE2-70, some people will encounter the following warning messages:

Error: more than one programming cable found in available hardware list
-- Use -- list option to display available hardware list and specify correct
Cableprogramming

This parameter information, mainly said that there are more than two cable can be used, the nios2-configure-sof does not know which cable to use, why is this not clear? It is probably because USB blaster is used in different USB ports, this caused every USB port to have a USB blaster driver installed. I did not receive this alarm.

Solution
Step 1:
Use jtagconfig to indicate which cable can be used currently

As shown in the following example, the current cable 1 is on the DE2-70

Step 2:
Use the -- cable variable number to specify which cable to use

As shown in the following example, cable 1 is specified. you can adjust it according to your actual situation.
