cde, Thanks for the info. That worked. Now I just to try to figure out why that works. Gordon

Hi, I have a MSP-EXP430G2 Rev. 1.4 with ....G2231 installed. I have disconnected the on-board emulator supply by removing the J3-VCC jumper. All info on the web and TI literature that I have found so far state that to power up the MCU, I must provide a 47K pull up from RST to VCC (3.6V). The schematic for the Launchpad indicates that the pull up is actually on the board already. Whether I assume that the on-board pull up is really there or connect my own external resistor, the mcu will not power up and begin execution. The only thing that seems to work is to tie RST directly to VCC.
