MK60DN512ZVLL10 芯片下载问题，搞了好几天了，求助啊

taokwf · 发表于 2013-10-7 19:31:59

求大神，求飞思卡尔技术支持
买了10块的K60芯片，现在焊了7块，只有一块能用，其他的都废了，出现了这样的问题，网上找了几天了也没找到解决方法，请各位帮忙看看啦。
开发环境：IAR6.5
下载器：J-LINK和JTAG
芯片是我自己手焊的，焊过之后下载，直接就不能使用，下载出现的情况如下：
首先用JTAG下载器，点击下载，出现如下的界面

下面的LOG是：

然后使用J-LINK下载，点击下载，出现的情况如下：

目前已经能够保证排除的问题：
1、PCB的问题，因为焊了6块，其中一块儿能用，即使是电路有问题，如果我只焊了普通的复位电路，也应该是能用的，但是也不能下载，故排除了PCB的问题；
2、工程选项的设置问题，相同的设置下载其他的芯片没有任何的问题，故工程选项的设置不会有问题；

下面是我采用J-LINK ARM进行调试的结果：
1、点击Target-Connect结果如下：

之后Check Blank，显示如下的窗口：

点击 erase sectors 和 erase chip出现的提示框和check blank 是一样的

使用K60也有一年多了，这次改进了一版PCB，竟然出现了这样的问题，十一都扔这上面了，哪位明天上班看到了帮忙想想办法啊，6块芯片躺尸中，要哭了啊

今天又进行了新的测试，将7块儿芯片中好的一块和另外一块有问题的芯片交换了PCB，结果是好的还是好的，不行的还是有问题的，所以，可以确定就是芯片的问题了，但是这个问题究竟是什么还不是很确定，期待大神求解

用万用表量下复位脚的电压，
小于0.8V 就有可能芯片锁了
焊接温度最好300度

嗯，测过芯片引脚的，是小于0.8V，焊接的温度因为在300度的情况下焊锡无法融化，因此才采用了其他的烙铁来焊。
但是其中一块，我拆了又焊，还是好的啊。
就是芯片被锁的这种情况怎么解锁啊，找到的几个解锁方法也都实验过了，不行啊
