我做了简单的LCD上显示一串字符,在IDE下,run as instrustion set simulation时,可以看见输出字符.但run as hardware时,出现提示:
Using cable "USB-Blaster [USB-0]", device 1, instance 0x00
Pausing target processor: not responding.
Resetting and trying again: FAILED
Leaving target processor paused
板上LCD没反映.
“run as instrustion set simulation”是调试机模拟的,没有在硬件上运行。
这种情况多半是硬件问题。你的“program memory”是什么?检查一下连线,如果是SDRAM,再检查时钟。建议先在Onchip ram上试,就不会有时序问题。 |
