failed to execute :wsl dos2unix create-this-bsp.............................. - failed to execute :wsl dos2unix create-this-bsp.............................. Dear Expert and Support, I was very glad to find the link that mentioned the problem and claimed solved. failed to execute :wsl dos2unix create-this-bsp; ./create-this-bsp --cpu-name nio2_gen2_0 --no -make - Intel Communities But, I feel very pissed that I totally don't understand what this is talking about. Consider that some newbies like me, could anyone be kind enough to use some plain language and write a step-by-step instruction. the Quartus and Nios eclipse environment are in Win10, is there unix/ Ubuntu 18.04 in the win10 quartus installation? it is so confusing. I encountered this problem while I was following the instruction of an814. Thank you, appreciate your help.
