I recently met a serious problem.
The situation is like this:
Serial communication is the main thing i’m focusing on. I use a computer to burn the firmware and then move to other computer to run. Serial port works fine if i run it after burning directly without moving. But not so lucky if i unplug the usb cable and replug into other computers. What even strange is, when i took the board back to the burning computer to run, it keeps dead. However, after reburning the firmware, it works again, and this way always works.
I kind of figured out that it is a problem about the serial port is messed up, so i use “minicom” command to fix it, but only works for some of the computers, for the rest of them, i really have no idea. But one thing i sure is, the problem caused by serial port.
Does anyone have the same problem? and Why? Why? Why?
I’m using arduino-0017 on a linux computer and all the other computer using linux too. I use IDE to burn the firmware.
