CC1310:在接收的回调函数里, 调用uart_write函数, 卡死
uart的配置没有问题，因为在配置完之后打印，成功
但是我想打印接收到的数据，在接收的回调函数里，调用uart_write函数，程序就会卡死
后来我又想在回调函数里建一个flag，然后在主程序里用uart_write打印，还是不行
请求帮助！
看到你在E2E上发的帖子了，关注一下E2E上的答复。

E2E中关于你这个问题的答复如下：
You are calling Display Driver functions from your callback, it is not possible to do this in a HWI context, it must be done in a Task context.
另外，
我这边也测试了一下，将串口打印从callback中移出来之后，可以正常打印并继续运行。
