I have install latest(2020-05-27) raspberry pi image 32-bit. And it gets on rainbow screen on both outputs, red lights is on, while green lights flashes 4 times.
When I turn on raspberry pi with out sd-card I get bootloader message.
When I put EEPROM from raspberry pi imager I get green screen that is on for minute then it turns off.
On LAN port orange LED turns on and on my network switch green LED flashes like on other devices, but raspberry pi doesn't show on nmap scan.
I have read and tried all things from:
And nothing worked I don't know is my raspberry pi dead or is there some error.
I have tried to install both on 64GB sd and 16GB sd.
Power supplay is 3.5A and 5V.
