I'm afraid I'm coming to this rather late, but I have had a Rock64 for about 2.5 years running Stretch and I want to upgrade. After seeing that this board is listed as CSC, I found this thread and was wondering what exactly CSC means? When did the board become CSC? Is there a particular build I should stick to for upgrade (such as just doing a modest upgrade to Buster)?
As I write this, I'm wondering if the reason that I haven't been able to update some software recently via CL is because it is listed as CSC? This is the first time I've had hardware become unsupported, so I'm not certain what to do.
