i have always used external + jtag power supply without any problem. and you should use it, otherwise, when the led will blink, you will notice that the lcd loses power with the same timing.
r u able to reprogram the board? i remember reading something about fuses on the msp430. that the user code is protected, and to reporgram it, you have to pass the correct password. and once the fuse is blown the code on the processor is not accessible to anyone (this is used for final productions of msp430 + some company's proprietery software) so that no one can steal the code. but in this case, you should not be able to reprogram the board, and should get the error everytime, instead of intermittently. hope it helps. karan CM II Resolution Systems Inc.
