OpenSprinkler Forums OpenSprinkler Unified Firmware Firmware Update Problems (Hardware version 2.1) Reply To: Firmware Update Problems (Hardware version 2.1)



Thanks for the info. My main problem had been clicking Auto Detect. Now the problem seems to be the driver. I loaded the drivers on a Windows 7 box using Zadig. Zadig reported that the drivers were installed successfully. When I try to upload the firmware, it fails and the output log says

avrdude: error: could not find USB device “USBasp”

What should I see in device manager under USB? When I plug in the opensprinkler in bootloading mode, the device manager window flashes as if it’s updataing but I don’t see any new device under USB?

Any help or suggestions would be appreciated.
