UVISION 3: CAN'T DEBUG WITH USB TO RS232 ADAPTER (XC164CM)

Georg Mayr

I have a PC which doesn't have an RS232 serial port. I use a USB-to-RS232 serial adapter cable (vivanco usb serial adapter) to connect the PC to my XC164CM Starterkit-board.

When I try to debug, I receive the following message:

Connection to Target System Lost

Although all settings (COM port, baudrate,..)are adjusted.

If I use another PC that has an RS232 serial port I can connect and debug with no problems. Does the debugger work with a USB-to-RS232 adapter, with the XC164CM Board?

    Hi,

    USB to serial adapter are not fully compatible with an RS232 port. The problem is the timing, especially if handshaking is involved.
    So if your starterkit need some timing on handshake lines (for example to get into boot mode) an USB to serial adapter can miss the timing.
