That implies you still have a dt-blob.bin file in /boot
I see there is a file "dt-blob.bin" in /boot....I assume it was put there by the installation, since I don't (yet) know anything about a "blob" ...I need to study your good link. Is this something that was automatically set up? Note the only display I'm using is an HDMI display.
Should I delete this blob file? I don't need any special config, that I know of (of course, what is considered special).
...I remember a few days ago, someone suggested I go to this page:

There's a dedicated Compute Module section here in the Forum where your CM3 related questions might be better suited.
Is your I2C configured correctly - i.e. via custom device tree blob?
Look i.e. here for some examples/hints: https://www.raspberrypi.org/documentati ... display.md
More Details might be found in the device tree section of the forum
so i went there & by the way I did try, hoping it would get my i2c port0 activated:
sudo wget https://goo.gl/htHv7m -O /boot/dt-blob.bin
however sudo i2cdetect -y 0 still shows an error (nosuch file or directory)
sudo i2cdetect -y 1 shows dashes & anything connected to i2c bus 1
This was vague & lousy advice, since they should have simply said:
You need to add dtparm=i2c_vc=on, rather than messing with a "blob"
is there a way to undo this blob?
