I am using development kit TWR-K53N512.

* Originally OSBDM/OSJTAG firmware version is 29.07, I can see three drivers in Device Manager (as expected):

----  Jungo                                -> PEMicro USB Serial Port (i1)

----  Jungo                                -> WinDriver

----  LibUSB-Win32 Devices   -> Open Source BDM - Debug Port

* "Terminal Utility" of "OSBDM OSJTAG Virtual Serial Toolkit" works fine!

--- "Open Serial Port" always success!

 

* After updating the OSBDM/OSJTAG firmware to version 31.21, I can see three drivers as expected:

----  Jungo                                -> WinDriver

----  LibUSB-Win32 Devices   -> Open Source BDM - Debug Port
----  Ports (COM & LPT)          -> OSBDM/OSJTAG - CDC Serial Port (COM16)

* However, "Terminal Utility" of "OSBDM OSJTAG Virtual Serial Toolkit" is not working anymore!

--- because "Open Serial Port" always fail.

 

Anybody has the same issue? How to fix?

Thanks!

 

Jerry
