LTC4040 Charging Issue

Hi All,

I am using LTC4040 to charge 18650 battery and to generate 5V output. Boost section is fine but charging of battery is not working.

I have removed NTC and grounded the PIN. And now LED connected to RST and CHRG pin is flickering alternatively.

PROG pin is showing 0V.

added extra info
