Other Parts Discussed in Thread: MSP-EXP430G2ET
Dear Experts.
I'm developing a board using the MSP430G2553(DIP20pins).
I'm in trouble.
The MSP430G2553(DIP20pins) is mounted on a board under development.
* Connect 10V/22uF and 16V/0.1uF between the 3.3V power terminal (#1) and the GND terminal (#20).
* The reset terminal (#16) is pulled up at 47k-ohm and grounded at 16V/1000pF.
* And the TEST pin (#17) is pulled up at 47k-ohm.
* Removed all other wires.
Connect at Spy-by-wire from the launchpad's 7-pin connector to the target board.
[launchpad: MSP-EXP430G2ET]---[target]
3V3--------(#1) 3.3V power
GND--------(#20) GND
SBWTDIO------(#16)/RES,SBWTDIO
SBWTCK-------(#17)TEST,SBWTCK
Power is supplied from launchpad.
1-- Build the project .....complete without error.
2-- Start Debug .....start communication to the target board.
3-- Wait for a while until the dialog disappears ......maybe writing...
4-- Click [Resume] button ....The program runs and works as intended.
6-- Click [Terminate] button.
7-- Disconnect from launchpad.
8-- When the target board is energized alone, it works as a stand-alone.
In this way, It's been working very well. 2 months ago.
I am doing the same now.
1~7 do not change behavior.
8-- Program does not run on target board alone. why?
******** The problem I'm having now is... ********
* Successful debugging from launchpad. Works fine.
* Power off. (wait a few seconds until the power is completely off.)
* Power on again.
* But the target doesn't work. <==== I'm stumbling.
I need your help.
thank you.
