When I want to build my program from Matlab into the ezdsp I got the following problem.

"Error: File: C:\Program Files\MATLAB\R2011a\toolbox\target\extensions\processor\tic2000\blks\mex\tlc_c\c280xgpio_do.tlc Line: 23 Column: 36 The left-hand side of a . operator must be a valid scope identifier"

What can I do now? I will be very thankful to you for your reply.

This might be a bug, please report this to MathWorks Tech Support to verify that and see if there is a workaround/solution.

Thank you for your valuable reply.Is it problem in my design or matlab & CCS ? Please assure me.

It could be both: you might have a problem in your design

andMATLAB has a problem in generating the code.## c.m.f.s. (view profile)
