To Update OSCA

Download the latest version of the OSCA config .bin file (Make sure you get the correct version for your board revision) and use the FLOS-based EEPROM.EXE tool.

1. Choose Option 1 "Write config to slot".
2. When asked which slot, choose a currently inactive slot
3. Use the load requester to locate the .bin file (use the RS232 option to send it via serial link)
4. Wait for file to load, write to the EEPROM and complete verification.
5. Choose Option 2 - "Reconfigure from a slot now" (Non-permanent)
6. When prompted, choose to reconfigure from your chosen slot
7. The FPGA restarts with the latest update. This selection persists until power off.

If everything is OK, you can reload the EEPROM tool and choose option 3 to make the new Slot the Active Slot. Of course, the next time you update OSCA, it'd be best to choose one of the other slots.

If you want, you can just rewrite the currently active slot (EG: Slot 1) in the first place, but the method above allows you to test the new config BEFORE making it default. IE: If you overwrite the current Active Slot with a bad config, the FPGA will not start at power on and you'll be forced to use one of the emergency options to sort it out.
