The DSP is C6455, I use the EDMA example in SPRC234 with no modification, the project is in default_package\csl_c6455\example\edma\edma_interrupt\build, however, after I run it, the programme always stops at "while (!intFlag);", it seems there is no EDMA transfer complete interrupt trigger the interrupu servive function.The example provided by TI should work. should I have to do some operation before using the example, such as UNLOCK.Could you tell me some tips?
