Try this:I would normally recommend you to be very reluctant to run random downloaded scripts, especially with sudo, but I basically control this repo and know the script well.
Assuming I got that right, you should end up with a file called visionbonnet.eep. Please attach it to a reply.
Try this:
Code:
$ wget https://raw.githubusercontent.com/raspberrypi/utils/refs/heads/master/eeptools/eepflash.sh$ sudo sh eepflash.sh -r -y -a=50 -t=24c32 -f=visionbonnet.eepAssuming I got that right, you should end up with a file called visionbonnet.eep. Please attach it to a reply.
