I am trying to get Venus running on a pi4 2gb with the 7" touchscreen. Using the latest venus large image from 1/13/21, it won't boot and fails with the error message that start4.elf is not compatible. I replaced the start4.elf with the latest version from raspberry github and it did boot to the raspberry pi login. I'm new to this and have no idea why that worked or if it broke something else.
The problem now is that it doesn't appear on my network so I can't ssh to it. Attaching a USB keyboard doesn't work either.
Before trying this I did run a standard pi release on it and everything worked fine so I'm confident my pi and its various connections are working.
Since I'm new to this I probably did something stupid. Would appreciate any help I could get with this.
