I have a C5402 DSK Card and having problems getting my assembly programs going immediately to the start of the program upon a DSP reset. My example program is : .sect ".vectors" B main .bss var,10 .text main: LD #1,A again: STM #var,AR1 STM #4,AR2 loop: STL A,*AR1+ BANZ loop,*AR2- ADD #1,A B again My linker command file is: MEMORY { PAGE 0: PROG: origin=0x0080,length=0XFF00 VECS: origin=0xFF80,length=0x007F PAGE 1: RAM0: origin=0X0060,length=0x0020 RAM1: origin=0X0080,length=0x1380 RAM2: origin=0X1400,length=0xEC00 } SECTIONS{ .vectors: {} > VECS PAGE 0 .text : {} > PROG PAGE 0 .data : {} > RAM1 PAGE 0 .bss : {} > RAM1 PAGE 0 } The project compliles okay. But when I load the resultant coff file, a "data verification error at FF80 occurs". I think my problem is with the vector memory definition in the linker command file. Is the start of the vector area in the C5402 FF80 correct ? Looking at TI's memory map of the C5402 it is correct, however, I have seen some people use origin=0x0080 and length=0x0080 for vectors. Can anyone set me straight ? Maurizio Gencarelli Royal Australian Air Force Australia |
