    RE: Untraceable problem with minicom
    To Rubberman, The baud rate is correct; it is 115200. I know this because when I use the custom software the boot messages show that the baud rate for the UART on the board is 115200, hence the baud rate on minicom should be the same. As for the other settings, I have already provided the details of the settings I make in minicom. Are there any mistakes there? Am I missing any other steps?

    Untraceable problem with minicom
    Dear all, I am facing an untraceable problem with minicom. Allow me to provide proper details so that it will be easier to provide assistance. I am using a desktop PC with Ubuntu 10.10. It has only one serial port (ttyS0) and I have verified that using the command " dmesg | grep tty ". My development board is called HDP6410, which is a clone of the SMDK6410. The processor is S3C6410 with ARM 1176 JZ(F)-S core. After I start minicom, when I connect the board to the pc using a null-modem cable and power up the board I am supposed to see booting updates on minicom, followed by a prompt that would allow me to access the board. However, I do not see anything. I know that the serial port on the pc and the serial cable are fully functional because I do get all the booting updates and prompt when I use a custom serial communication software provided with the board. However, I want to use minicom because the custom software provides no means of transferring files. I added my username to the following groups : dialout, uucp and tty. I have also checked that ttyS0 has read/write permissions. My settings in minicom are as follows: Serial Device : /dev/ttyS0 Lockfile Location : /var/lock Bps / Par / Bits : 115200 8N1 hardware flow control : no software flow control : no I have tried running minicom both as normal user and root, but I still get no output on the console when I power up the board. I know for sure that the serial port on the board is working fine and it does send messages once I power up the board. Something is wrong on the PC side. For some reason when I run minicom, the connection is probably not established on the PC side. Am I missing any essential configurations / settings ? I would highly appreciated some guidance on this. I have been trying for a week now without any positive result. Please help. Sincerely, Shan
