RPi 4B won't start with home assistant image, shows 4 led flashes

Installation
1

I’ve been trying to install home assistant for the first time, I have a RPi model 4B, I grabbed the model 4 32-bit image from the installation page (https://github.com/home-assistant/operating-system/releases/download/3.13/hassos_rpi4-3.13.img.gz ), loaded the image onto a 32GB SD card with dd, then I added a network configuration file, and resized the data partition to fill the rest of the free space.

When I try to start the rpi it just shows 4 flashes on the green LED and repeats this, so it isn’t booting. I tried installing a different image (raspbian) onto the same SD card & the same power supply and it boots, so that suggests to me that it is the home assistant image that it doesn’t like. The only info I could find is that it could suggest that it won’t load the start4.efi file (https://elinux.org/R-Pi_Troubleshooting#Green_LED_blinks_in_a_specific_pattern ). I checked the md5 of the file and the file on the SD card matches the one on the image I downloaded.

I don’t know where to look next, any suggestions? thanks

I found a more recent image on github https://github.com/home-assistant/operating-system/releases/tag/4.6 , and that one boots ok.

Just to note, the next time use balenaEtcher, as stated in the documentation. dd doesn’t correct any errors while writing to the sd-card.

Ok thanks. I tried installing it twice and it did the same thing, and when I installed raspbian and the new image it worked both times. Do you think that error checking could still be the cause?

I have a new issue where I’m trying to run a program that connects to energenie devices using a pi hat, and it won’t run because it can’t find /dev/mem, i’m not sure if using the new package version is related
