w*s 发帖数: 7227 | 1 For my embedded linux board, i can attach serial line during debugging,
then i can see my debug message from printf.
Now in the customer site, they won't have serial cable.
i cannot afford to print message to a file all the time.
what should i do ? | l*****s 发帖数: 2109 | 2 利用sys log?事后察看log ?
一般来讲,即使不保留rx tx针,也可以保留两个触点,自己往上搭线,老板子都是这
么干的。 | l****r 发帖数: 175 | 3 同问。
我的机器连串口都没有,除了dmesg,怎么看log? 能不能仿真串口?输出到文件什么
的?
