based on this scenario downloading the fw.bin file and replace it with the lib/firmware/hailo/ helped me
Here are the solution:
curl -o hailo8_fw.bin https://hailo-hailort.s3.eu-west-2.amazonaws.com/Hailo8/4.20.0/FW/hailo8_fw.4.20.0.bin
mkdir -p /lib/firmware/hailo
cp hailo8_fw.bin /lib/firmware/hailo/
After this line just restart the device. This worked for me
