Have you used a voltage meter or oscilloscope to check the voltage
level? Have you measured the resistance between SRESET and GND and
between SRESET and supply? Have you checked if your processor pin
is connected? Probably either the pull-up resistor isn't mounted or
your PCB is defective.

With best regards
