OpenSprinkler Forums OpenSprinkler Unified Firmware Error code: 0x2D ? Reply To: Error code: 0x2D ?



Okay, I figured it out. This has to do with a problematic SD card in the controller. I removed the card, found the formatting was corrupt, re-formatted as FAT32 and put it back in. Things worked properly. Was able to get the firmware updated.

Note: the updater program, running in Windows 10, wouldn’t detect the OpenSprinkler controller… UNTIL I started the program using the “run as administrator” option.
