蓝点UWB在接收和发送时卡死的问题！求解

云锡

买了一套蓝点的DW1000定位模块，在发送时和接收时都遇到了一个问题。就是在这条语句上卡死。   while (!((status_reg = dwt_read32bitreg(SYS_STATUS_ID)) & (SYS_STATUS_RXFCG | SYS_STATUS_ALL_RX_ERR)))  {
//printf("接收失败！");
};
接收时能接收到数据，但是过一会就卡死在这了。如果打开循环内的注释，系统就不会卡死。经过在线debug，发现卡死的时候，这个条件中的寄存器值在与运算后是0.接收测试的结果如下：

这是加了打印语句后的不会卡死的情况。
不加打印卡死的测试情况如下：

现在的情况是卡死的地方。
请问这个问题有解决的办法嘛？？？搞好久了，求大神解答~

测试过了。最后把我写得全部屏蔽了，还是会卡死，没有找出来原因。最后重新写了代码，不会卡死了，但是现在 ...

我们的代码，不做任何更改也会有问题？
拍个视频出来看看

测试过了。最后把我写得全部屏蔽了，还是会卡死，没有找出来原因。最后重新写了代码，不会卡死了，但是现在在发送端发送快，接收端接收慢，所以导致数据丢帧厉害。开始以为是发送端太快，接收端没办法处理，后来把发送端改慢，结果发现改慢以后接收端的接收速度也同样变慢了，数据还是丢帧。请问对于解决这个问题有好的建议吗？

哦哦,找了很久没找到原因。就卡死在这个循环的条件里，读出时间寄存器的值经过逻辑运算后是0。。。

那你用我们资料包原始代码测试
如果自己改，加一句代码测试一次，看到底那句加的出问题了

首先明确 和你讲   的确不能加打印，卡死再找其他原因。打印不能加！

但是不加打印就会卡死欸？？

UWB 调试不能随便加打印。
打印相对uwb非常耗时
如果B模块等待A模块信息，而A模块多加一行打印，打印完了，但是此时B可能已经timeout了。A再给B发信息，B就收不到了。
