N76E003 ISP进入APROM复位的问题

只看该作者 · 2019-5-18 11:30

想请教各路大神，关于官方提供的ISP代码中，我进入APROM后，While的循环只跑一次，就回到程序入口了，是怎么回呢？
配置中，看门狗已经关闭。

如果官方程序都不能跑成功，先看看配置字是不是出了问题。

完全跑的官方原版例子？

while不是死循环？

总是复位？

用的是Nulink在Keil下在线调试的，接了5根线的裸片，没有动过配置字节。
也好郁闷中，是不是Nulink不能这样仿真呢？

是的，就在最后的While后跑了个IO翻转的动作，我想看看它会不会持续在APROM标号后的while下一直跑。
目前没有解决。

这个是ISP 烧录到LDROMD 的吧，要设置LDROM，
