Hi!, We are trying to download a small sample program to internal memory of ADSP-21060 through JTAG (White Mountain DSP). The code is getting downloaded in the internal memory but "seg_rth" segment of Internal Memory are NOPS, hence the program counter doesn't jump to the main program. The program counter remains at location "20005" and goes to infinite loop. I am able to write to the other segments of Internal Memory. There is no Flash and only the Processor along with power circuit is present on the Board. Regs, Anshuman Sethi __________________________________________________ |

You need one of these 060_hdr<_XXX>.doj files in your executable
(.dxe). This code, which resides in the first 256 48-bit locations (in seg_rth) in internal SRAM starting at 0x20000, does some initialization (initializes some processor registers, initializes the stack and heap) and then executes a jump to _main. I'd start by reviewing the LDF file. It should link in one of the following: 060_hdr.doj (if you are using C) 060_cpp_hdr.doj (if you are using C++) 060_cpp_hdr_mt.doj (if you are using C++ with threads) See the default ADSP-21060.ldf file (under .\VisualDSP\21k\ldf\). This does link in one of these files. Look at the linker output and the resulting map file. I suspect this 060_hdr<_XXX>.doj file is not being linked in.
