Issue
New system image cannot be written
Environment
LonMaker
NL220
Vista
LNS
Cause
This error will be generated if you invoke the LoadEx method on a device, but the system image cannot be written, probably because it is not stored in flash memory.
Resolution
The old system image will remain intact if this error is thrown. However, the device will remain applicationless. You should load a new application image into the device with the Load or LoadEx methods in this case.
