The reason for not counting was a cold solder junction at the enameled copper wire what does the modification of PCB from T2-CH4 to T3_ETR pin. As soon as there is a signal with edges at the ETR pin, the above posted code increments the counter like expected.

>no matter what I tried I couldnot count ETR pulses

Try the code from above and check your ETR pin for present pulses. If they are missing, there must be a hardware bug...

dont waste your time trying to count ETR pulses

no matter what I tried I couldnot count ETR pulses

There must be a hardware bug

try counting CH1 pulses instead
