It is a little picky.
IIRC the target serial port must be some specific chip. Hight check that…

Hi Thomas,
On the target I installed WinDbg.
But I still can not connect from the host to the target.
After the WinDbg installation on the host I ran again:
bcdedit /debug on
bcdedit /dbgsettings serial debugport:1 baudrate:115200 reboot
Did not try yet Pavel’s solution to change baud rate to 9600.
On the target + host I ran Hyper Terminal both configured to 115200,8,n and
tried to send few characters from target to host.
It worked fine.
Best regards,
Z.V

Have you installed debugger on target?
WDK 8.1: Use WDK Test Target Setup (a MSI) WDK 7/SDK: Install, but select
debugging tools only…
Good luck!

Hello,
On a target running windows embedded 7-32 I ran (from CMD):
bcdedit /debug on
bcdedit /dbgsettings serial debugport:1 baudrate:115200
Then I rebooted the target.
On the host PC I ran WinDbg and chose Kernel Debug and set baud rate, port.
Using HyperTerminal I can see that the line between the 2 PCs is OK.
When I tried to ‘break’ nothing happens. I failed to get the prompt.
On the Windbg I’m getting:
Opened \.\com1
Waiting to reconnect…
Can you help ?
Best regards,
Z.V
