In this article, nonMaster Frescos refer to all Fresco devices that are not ethernet capable (controller id 2-99). Master Frescos on the other hand are the Ethernet connected controllers with controller id 1.
There is a compatibility issue when attempting to update nonMaster Frescos over Ethernet when a Master Fresco is on firmware version 201.xx and the nonMaster to be updated to a version prior to 201.xx. The following things can be done to work around this issue:
- When using Fresco Studio, select update all which will first update the nonMasters and then the Masters, this will prevent any issues.
- Update the nonMaster Frescos via USB.
- Downgrade the Master Fresco to firmware version 200.xx. Then update all nonMaster Frescos and then finally update the Master Fresco back to 201.xx
