Hi all,

Can we connect the reset line and +5V line with a 1k pull-up
resistor, to keep the reset line high? Out of the 8 circuit boards
with the same schematics I am building, 6 of them work in this way,
while the other two do not. For these two problematic ones, the reset
line is always jumping between 2.1V and 4.7V, not stable at all.

I feel like this 1k pull-up resistor setup should work for keeping
the reset high, but I cannot find out why the reset line is not 
stable when it is connecting to +5V by the 1k resistor. Or am I 
wrong, and do I have to connect the reset line with +5V directly?

Thanks a lot!
