About using the MCU-LINK SWD interface

[nefty]

Hi All,

I want to write to LPC802M001JDH20 using the MCU-LINK SWD interface.
When I type the following command line from the Windows command prompt, I get the response "ERROR: Unable to communicate. No serial number for interface".
What is wrong with my command line?
Can someone please tell me what is wrong with my command line?
By the way, I can write from the GUI.

Command Line:
C:\>C:\FlashMagic\fm.exe --device LPC802M001JDH20 --mculink --erasedevice --program="C:\FlashMagic\ZZ_MyTest.hex" --verify="C:\FlashMagic\ZZ_MyTest.hex"
