µVISION DEBUGGER: USING MON51 ON ADUC83X DEVELOPMENT BOARDS


Information in this article applies to:

  • C51 Version 7.00

QUESTION

When I try to debug using MON51 on a ADuC831 development board, I keep getting "Connection to Target System Lost!". I can download HEX files to flash, so I know the serial port is working and the serial communications settings for the emulator are correct. What's wrong?

ANSWER

Not all ADuC83x boards are populated with external RAM. MON51 requires von Neumann RAM, so it cannot be used on these boards. If you have one of these boards, you should use the ISD51 debugger available in the PK51 development tool kit.
