I tried booting my new raspberry pi4 ,i have installed the recommended software as on the Raspberrypi official website .when i try booting the pi ,initially when the power is supplied both led pwr and act ,show up for 4 sec then after the ACT led starts blinking in irregular pattern for 4-5sec and then fades off(during this the red led stays on ).
I even reformatted my sd card 2-3 times and tried booting up the PI but no success. i am using sandisk ultra 32gb sd card and booting the pi using the raspberry pi's official pwr supply.
i'm trying to boot the Pi using headless setup ,i also created the ssh file and wpa_supplicant.conf in the BOOT folder.
I'm attatching the link of video of the blinking pattern :[https://youtu.be/7wO5KtBh52Q]
ps:I also powered on the PI without inserting the card to ensure if both led are working ,(both the leds stay on in this situation)
