Why Nios II cant open

[Khoo]

Why Nios II Software Build Tools for Eclipse (Quartus Prime Lite 20.1) can not open? Only can open once after download, after that had no response. I had tried to re-install and also download but still the same.

Hi @Khoo,

Thank you for posting in Intel community forum and hope this message find you well.
For quartus version 19.1 onwards both standard and pro, the NIOS SBT would required to have a separate installed steps perform after the quartus installation.

Further clarify, is that steps being perform?
Detail of the steps can be found here, and let us know if that helps.

Warm regards.

Hi @BoonBengT_Altera, sorry for late reply, I downgrade my Quartus Prime from version 20 to version 18, now the Nios II is working well. Thank you.
