Hailortcli fw-control identify not returning anything

I had hailo 4.20 installed on my raspberry pi 5, but it had some issues with hailo-rpi5-examples, which required me to use 4.19. I tried completely uninstalling hailo, removed all halo related directories and files, and removed everything hailo related from ~/.bashrc. Then, I tried reinstalling it, both with

sudo apt install hailo-tappas-core=3.30.0-1 hailo-dkms=4.19.0-1 hailort=4.19.0-3

to install hailo 4.19, and

sudo apt install hailo-all

Before each time I completely removed hailo, and started with a fresh installation, and both times running

hailortcli fw-control identify

returned nothing at all.

I did not try this on the first reinstallation attempt, but on the second I also tried

dmesg | grep -i hailo

which returned

I don’t know what to do, and I don’t want to have to wipe my SD card and re-flash RPi OS.

I’m not entirely sure what I did, but it is working fine now. It may have just needed a power cycle.

Hey @joshhtgould,

Usually we run reboot right after running the installation. In your case, the Max_desc_page_size wasn’t set because the driver wasn’t up (my guess). Happy to hear it worked!
