[quote user="Prasoon Srivastava54833"]I created a new project for TMS320F2808 on CCS Version: 5.3.0.00090, added few files and compiled the project. For some reason the linker in not seeing sections defined in DSP280x_Header_nonBIOS.cmd file and giving unresolved symbols error. Attached is the the zipped project folder for your reference. Please advice.[/quote]This is a project which uses controlSUITE. The symbols which are reported missing are those defined in controlSUITE device support source files, e.g. DSP280x_GlobalVariableDefs.c, but which aren't part of the CCS project.
To resolve the undefined symbols the appropriate controlSUITE device support source files need to be added to the CCS project.
P.S. some of the source files are marked "STRICTLY CONFIDENTIAL", did you mean to attach them to a public forum?
