小弟初学DSP，用TMS320VC33在线烧写AM29LV160D,发现无法写入，能正常擦除，其擦除和写入一个字的子程序如下： volatile short *flash_addr=(volatile short *)0x1000; void Erasechip() { short *ctrl_addr1=(short *)((int *)flash_addr+0x555); short *ctrl_addr2=(short *)((int *)flash_addr+0x2aa); *ctrl_addr1=0x00aa; *ctrl_addr2=0x0055; *ctrl_addr1=0x0080; *ctrl_addr1=0x00aa; *ctrl_addr2=0x0055; *ctrl_addr2=0x0010; wait(20); } void writeword() { short *ctrl_addr1=(short *)((int *)flash_addr+0x555); short *ctrl_addr2=(short *)((int *)flash_addr+0x2aa); *ctrl_addr1=0x00aa; *ctrl_addr2=0x0055; *ctrl_addr1=0x0080; *ctrl_addr1=0x00a0; *pa=pd; asm( "nop " ); asm( "nop "); asm("nop"); } 请高手看看我的程序什么地方有问题！谢谢！！ [align=right][color=#000066][此贴子已经被作者于2006-10-3 23:24:49编辑过][/color][/align]
