I have used an RPI4 B, which is fine with USB booting, but when I try to boot from the SD card, it gets stuck on the Rainbow Screen. Initially, the green LED blinks and then stops. When I used Ubuntu OS with an SD card, the green LED blinked and got stuck in the same Rainbow screen. EPROM uptodate as well. Can you help me to fix this? Thankx
