I'm trying to get ECU to work on omap l-138. I've successfully linked libs and build my app but I always get an error in ecuNew.
My configuration:

ecuNew ERROR
EXC-id:fc, Type: 2, Code: 1 len:0
//----------------------------------------------------------------------------
When I call ecuOpen even after error in ecuNew I get exception
but can't find in documentation how to interpret this exception.
Any help would be greatly appreciated.
