BBB Wireless - uart0 serial debug console failed after upgrade from default Debian 8.6 to Debian 9.4

[bohl...@gmail.com]

Hi,

I just bought two BBB Wireless boards.

The default image, Debian version is 8.6 - I am able to use PUTTY for serial debug console.  

But after I have upgraded to latest Debian version 9.4, my Windows Computer Device manager can still detect the serial port, BUT PUTTY for serial debug console is NOT responding anymore.....

I use remote SSH to login, and see that ttyO is still enabled

# dmesg | grep ttyO

[    0.000000] Kernel command line: console=ttyO0,115200n8 bone_capemgr.uboot_capemgr_enabled=1 root=/dev/mmcblk1p1 ro rootfstype=ext4 rootwait coherent_pool=1M net.ifnames=0 quiet

# cat /etc/os-release

VERSION="9 (stretch)"

What should I do to enable putty back for serial debug console use?

Note: the original image Debian info in the new BBB wireless board:

# cat /etc/os-release

PRETTY_NAME="Debian GNU/Linux 8 (jessie)"

Hi, 

Sorry I am new to this. I could not find my question in the forum....

Where can I find it?

Do I need to resend again?

Thanks in advance

Boh Lim
