在TI给出的例程中,在DSP5402最小系统(一般外扩SST39VF800A)中debug是跑不通的.
因为中断向量地址被安排在0xff80处,故应该将其移至0x0080处.
这样即可在RAM中调试,最终写入SST39VF800A中.
改写如下(DSP/BIOS在DSP5402最小系统硬件环境下运行良好):
/* MODULE MEM */
-stack 0x100
MEMORY {
PAGE 1: USERREGS: origin = 0x60, len = 0x1a
PAGE 1: BIOSREGS: origin = 0x7c, len = 0x4
PAGE 1: CSLREGS: origin = 0x7a, len = 0x2
PAGE 0: VECT: origin = 0x80, len = 0x80
PAGE 1: IDATA: origin = 0x100, len = 0x1700
PAGE 0: IPROG: origin = 0x1800, len = 0x2800
}
总之,VECT+IDATA+IPROG应该在0x0080~0x3fff之间.
