Due to a known issue with VisualDSP++ 5.1.1 where the ICE-1000/ICE-2000 can sometimes be updated with firmware for the ICE-100B, rendering the emulator unusable, we have released VisualDSP++ 5.1.2 which resolves this issue.
We strongly advise any customers using VisualDSP++ 5.1.1 to upgrade to 5.1.2 which which is available free of charge here. The Release Note for VisualDSP++ 5.1.2 can be found here.
