CODESYS error during download: 1 unresolved reference
Firmware for GRV-EPIC-PR1:
1.3.0 through 1.3.1
Resolved In Version:
In CODESYS Development System, when you add a data source (through the Data Sources Manager) to your application, and then download your application, you get the following messages:
unresolved reference(s), 0 signature mismatch(es), 0 version mismatches found!
This is because the device version on the hardware differs from the device version in the project.
In your CODESYS application, disable calls to the unavailable function by specifying the DS_LOG_WITHOUT_PRINTF compiler define:
- In CODESYS Development System, right-click your application.
- Select Properties.
- Click the Build tab.
- Type in DS_LOG_WITHOUT_PRINTF in the Compiler Defines field.
- Click OK.
