Pi4: gradient screen at boot

[popolon59 (Jean-Paul Lacquement)]

Hello,

I tried to install ParrotOs on my Raspberry Pi4 as follow:

1. I downloaded the latest image for Rpi:
   Parrot-security-rpi-5.3_arm64.img.xz

2. I use “raspberry pi imager” to burn the image on a sdcard

3. Once the image is burned, I boot the Pi

4. The displays show a gradient screen and do not boot the os

Do you have any idea ?

Thanks.
