Error while generating bsp in nios tool

[SERMASWATHIKA]

Hi Team,

We are working on migration project. Design is upgrading from 13.1 version to 22.1 version . In 13.1 version, exception vector of cpu is mapped to modified avalon and avalon is connected to DDR Memory. Now in 22.1 also, exception vector is modified same as 13.1 and error is showing for exception vector. 

I have attached the error below:

Please check the error in the attachment. After modifiying the exception vector bsp is generated successfully.

Want to know the reason for the issue.

Hi,

Starting with the Nios® II EDS in the Intel® Quartus® Prime Pro Edition software version 19.2 and Intel® Quartus® Prime Standard Edition software version 19.1, the Cygwin component in the Windows* version of Nios II EDS has been removed and replaced with Windows Subsystem for Linux(WSL)

Please refer below link on the WSL installation steps-

Same type of issue is also posted earlier on forum-

Hi Jeet,

Already ubuntu is installed in our pc and we compiled one board design without issue in eclipse tool. Now when we opened another board design in eclipse 22.1, again this error is popped out.

When i changed the exception vector from modified avalon mem to ddr_avl , it is compiled.

Thats why i am suspecting the exception vector of cpu .Can you please give clear guidance on this?

Hi,

Please confirm on below.

The working design is with the quartus and eclipse v22.1?

Also, The migrated design is upgraded from the v13.1 to v22.1 or you have created the design from the scratch in qaurtus v22.1 with the design reference v22.1?
