You are about to perform a migration to miniDSP Device Console (DC). You can see the device in the device list but can't connect to the unit as you're getting the following warning:
The issue is simply that you're running a firmware version that is lower than required to connect and upgrade firmware from DC. The first step is to upgrade your platform to run a firmware version greater than v1.5 which supports firmware upgrade from DC. From there on, all XMOS/DSP firmware will be possible from DC.
Please follow the "migration" steps found under your user downloads section. IT will clarify the whole process for you!
