I did go to beyondwind.duckdns.org/downloads/rockbox.zip and downloaded and installed this version. The Zheino 256gb zif ssd drive in my ipod 5.5 now works great. However, there is one problem.
The battery drains to nothing after the ipod has shutdown for an extended period of time, about 3 days. The battery just slowly discharges. When I press the center button and it restarts and I play a song, the battery indicator is much lower than when I turned it off.
Could it be that the SSD is drawing current?
The ipod video 5.5g was upgraded from a 240gb hd and it did not draw down the battery. In fact, I could leave it off for months at a time with little to no drain on the battery.
