The string does not print completely

[QIUZHILEI]

Hello, I am using your "ns16550s" library, I want to print a string every few seconds "This is uart device test.\n\r ", but when I debug, the terminal only prints "This is uart devi", and there is no line feed. Please look at this problem in your spare time.

Hello, I fixed the bug in the latest release, please let me know if it works now (I couldn't test it, I don't have the running environment anymore)
