Question

我在Jetson TX2上运行Node v8.11.3，突然而没有明显的原因，segmentation fault错误开始使我的应用程序崩溃。在注释了部分代码后，我发现导致分段错误的行是这一行：

var SerialPort = require('serialport');
const port = new SerialPort('/dev/ttyTHS2', { baudRate: 9600});

/ dev / ttyTHS2上的

我有一个通过UART连接的uBlox GPS。

如果我cat /dev/ttyTHS2，我可以完美地看到gps输出。波特率正确。

如何解决细分错误？另外，在哪里可以看到“核心已转储”？

Answer 1

好像是新SerialPort 7.1.2版本中的错误。回滚到6.2.2解决了该问题。

新的SerialPort（）引发分段错误
