Abstract:
A method of operating a target system having a digital signal processor, said digital signal processor having plural registers, the target system further having a link connectable to a host computer for debugging said target system, wherein said target system further has a memory having plural addressable locations, one of said locations being designated for storage therein of pointer information indicative of the entry point of a subroutine useable in debugging by said host computer, and other locations storing an application program, the method comprising:setting the contents of a predetermined one of said registers of said digital signal processor to a first value when said host is connected to said link, and to a second value when said host is not connected to said link; starting execution by said digital signal processor of said application program on said target system, wherein said step of starting execution comprises: reading the content of said predetermined one of said registers; when said one register stores said second value, writing a predetermined value to said one of said locations; when said one register stores said first value, leaving the contents of said one of said locations unchanged.
