I am having issues with the serial downloader.
What I need to do is to identify why the device is not communicating with the download tool. Do we have a typical troubleshooting list for our downloader and the ADI Microconverter line of products?
Here are the steps I would suggest to follow:
Step 1: Is the correct COM port selected in the CM3WSD?
After connecting the hardware to the PC, check in the device manager what COM ports are available. (see "Device manager.bmp" attached)
The COM port configured in CM3WSD should match the USB Serial Port number (if connected via USB) or Communication Port (if connected via RS232).
Step 2: Is the USB driver installed correctly?
If the eval board is connected via USB to the PC, check in the device manager that the USB serial port appears in the Ports list.
If it does not appear, the USB driver needs to be installed.
If using the USB-UART/SWD-CONVZ board from ADI, install the USB driver “CDM 2.06.00 WHQL Certified.zip” provided in the development system CD.
If using your own USB device, install the driver for the specific device.
Step 3: Is the device in download mode?
Try to communicate via SWD. If communication is possible then the device is not in download mode. pull P0.6 low, toggle reset and try again.
Step 4: Is the physical interface ok?
Place the device in download mode. Open HyperTerminal and select the USB Serial Port or communication Port. The baudrate must be between 600bps and 115200bps included. Select 8bit data, no parity. (see "COM properties.bmp" attached)
Press the back space key. The reset string should be displayed as described in the “Cortex-M3 based ADuCxxx Serial Download Protocol” application note. (see "reset string.bmp" and app note "AN-CortexM3downloadProtocol.pdf" attached)
Note that these steps are also valid for the ARM7-based products with UART downloader.
