Hi,

I'm using a USB/Serial adapter in order to connect to a Atmel NGW100 board by using its serial interface. Because I work with buildroot, I need a Linux environment and so I installed Ubuntu 9.10. But the serial interface in Ubuntu does not work, like it should be.
Here's what I did so far:

Host: Windows 7
VirtualBox: v3.1.6
Guest Ubuntu 9.10

USB/Serial adapter installed in Windows 7 as COM3. The adapter is working properly.

VirtualBox serial interface configuration:
Port number: COM1 (--> which is /dev/ttyS0 in Ubuntu)
Port mode: Host device
Port path: COM3

Next I tried to connect to the board:

Code: Select all

picocom -b 115200 /dev/ttyS0

and it returned

Code: Select all

picocom v1.4

port is        : /dev/ttyS0
flowcontrol    : none
baudrate is    : 115200
parity is      : none
databits are   : 8
escape is      : C-a
noinit is      : no
noreset is     : no
nolock is      : no
send_cmd is    : ascii_xfr -s -v -l10
receive_cmd is : rz -vv

Terminal ready

which is ok.
Now I can press the reset button on the board and this should display a message ("press space to abort autoboot") in the terminal. But it doesn't. Something must be wrong here...

Can anybody help me?

Best regards,
Andi
