Hi all,

Just been trying to add in dtoverlay=i2c-gpio and things weren’t booting (with the latest Rpi3 image download from today

HOST OS VERSION  
[balenaOS 2.58.3+rev1]

Came across this link saying that there was a broken dtbo with the size of the dtbo you provide

> This line in the /boot/config.yxy on my rpi3, gives the rainbow screen and the RPI3 does not boot.
> dtoverlay=i2c-gpio,bus=3,i2c\_gpio\_delay\_us=1,i2c\_gpio\_sda=23,i2c\_gpio\_scl=24

Replacing with the other version in /mnt/boot/overlays fixes the problem.

Could you update this in your releases? Ta!
