WARNING: Tcl script &ltfile name&gt error: Module "none" doesn't exist in SOPC design "nios_setup".

Description

Due to a problem in the Quartus® II software, if you uncheck Enable for any driver in the Drivers tab of BSP Editor for Nios® II, export a tcl file, and specify it as an option of some command like nios2-bsp, you will get the tcl script error.

Resolution

To work around this problem, open the tcl file in a text editor and swap the 2 operand of set_driver command. For example, if you disable led_io driver, you will get a line below.

set_driver led_io none

Then modify the line like below.

set_driver none led_io

This problem is scheduled to be fixed in a future release of the Quartus II software.
