and

Screen

How can I fixed it?

EDIT:

I changed usb cable and adaptor. But result is same.

  • so, you downloaded the centos image, good start ... when you say "the sd card is ready" ... what exactly does that mean? did you "burn" the image onto the sd card, or did you simply copy the downloaded image to the card? – Jaromanda X Feb 15 '19 at 8:16
  • though ... that looks like a pi1 - where did you get the centos image for pi? – Jaromanda X Feb 15 '19 at 8:18
  • Yes I burned into sd card. I think Otherwise, it doesn't come rainbow screen. @JaromandaX – Tota1907 Feb 15 '19 at 8:25
  • And i downloaded in centos web site. The file name: CentOS-Userland-7-armv7hl-RaspberryPI-Minimal-sda.raw.xz @JaromandaX – Tota1907 Feb 15 '19 at 8:26
  • Normally this is because you have a bad USB cable or power supply. And its an quite normal question, raspberrypi.stackexchange.com/questions/19354/… – MatsK Feb 15 '19 at 8:27

From the image in your question, it is clear that you have an original Pi B

The ARM chip in the Pi B (and A, and B+) is an armv6

There is no Centos image available for the original raspberry pi (armv6), only raspberry pi 2, 3 and 3+ (armv7)

There is a "definitive" list of available operating systems for the raspberry pi at this link ... note that under Centos (and others) it clearly states "Pi 2/3 Only"

The only solution is to buy a Raspberry Pi 2B, 3B, 3B+ or 3A+ - all of which have the prerequisite armv7 CPU (and are cheaper to buy than the original in my experience)
