在使用MDK 3.5 + JLINK V8调试LPC2132问题碰到以下问题：
开始的时候，先用LPC2131开发板自带的JTAG调试 总是提示：
Flash Sector 0 write failed!
Flash Sector 1 write failed!
Flash Sector 2 write failed!
偶尔也会出现
Flash Sector 1 write failed!－－ Sector 0和Sector 2 写成功了？
检查电路 晶振、电源和复位均没有问题。。。。
接着 用LPC2000 Flash Utility连接 一切正常，执行全片擦除命令后，重新用JTAG调试，还是同样的问题
尝试用LPC2000 Flash Utility将工程的.hex文件写到LPC2132中，然后使用用JTAG调试，成功
小弟思考良久， 不明白其中的原理，特来请教大侠们
另外， 在以上过程中，间或使用JLINK V8(正版－德国货)，连接正常 能够发现ARM芯片－－－附图
但是在移植了zlg的KeilULINK工程模板后，调试时总是提示：

移植后的工程模板在EasyARM 2200和2131开发版上都正常使用了，所以 请不要怀疑模板
请各位大侠不吝赐教。。。。。。。。。。。。。。。。 |
