nRF52840 power on led(Led 5) blinking continuously

[pankti583]

Hello,

nRF52840 led 5 blinks continuously causing reset and not performing code properly. I tried different USB cables but it still blinks. What could be the reason, is it only causing reset? and what can be done to make it proper?

Thank you

Pankti

Hello Esmaeill,
does the board shows up as "bootloader", after you pressed RESET when powering the board up?
Best regards,
Michael
