Hi David My PW28 board currently has settings to EXT for the power so it is supplied by a 3.3V plugpack. This will be the same voltage that is fed to my target board. Following Emmett's suggestion I will soon find out whether this is wrong. Thanks for the help Peter -----Original Message----- From: [email protected] [mailto:[email protected]] Sent: Saturday, 21 February 2015 10:30 PM To: [email protected] Subject: Re: [msp430] Problems with IAR and programming My memory of the 14 pin JTAG connector was of two different Vcc connections. One provided power from the FET to the target while the other was used to sense the Vcc level on the target and adjust signal levels. A quick check of slau278u shows two signals: VCC_TOOL VCC_TARGET VCC_TOOL provides power to the target while VCC_TARGET is used to sense the Vcc level. Having an external power supply connected to VCC_TOOL is just asking for trouble. -- David W.
