Nios II Eclipse report error when run the mem_init_generate command

[Rainwang]

i am working on a project with a Nios II inside C4 FPGA, which uses on chip memory as the RAM.

so after i build the project, i still need to run make targets-->Build -->mem_init_generate to generate the initialzation HEX file for the on chip RAM.

this works well so far.

but yesterday i must renew my laptop per the requirement from the company, and then i need to re-install the same tool chain: Quartus 21.1, WSL 18.04 on windows, CDT 8.8.1.

i believe i have done all steps per instructions, and the project can be built without error. but when i try to generate the HEX file, it reported below error.(I copied all information in the console window in case it helps)

please help me on this, thank you.

Hi

Could you check the WSL version that you are using currently?

It should be WSL version 1.

"wsl -l -v" To check the version

"wsl --set-version <ubuntu version> 1" to set version.

Hi

Just curious did you installed the required packages in the linux distribution?

https://www.intel.com/content/www/us/en/docs/programmable/683472/23-1/installing-windows-subsystem-for-linux.html

If you have done that, then could you try launching the eclipse ide with administrator privilege?

Hi, 

I checked my installation per the link you provided, all steps were done.

1. windows version: 22H2 19045.4651

2. WSL 1 and Ubuntu 18.04 installed.

3. windows subsystem for linux option turned on.

4. After reset PC, below commands were run.

sudo apt update

sudo apt install wsl

sudo apt install dos2unix 

sudo apt install make

sudo apt install build-essential

5. try to generate the HEX file, still the same error appears.

6. open the Nios II EDS with administrator privilege, also the same error as below:

Could you try adding a new environment variable below :

Name: WSLENV

Value: SOPC_KIT_NIOS2/p
