CM3+ w/ eMMC (non-Lite)?

[Flavor]

I just tried it with a 16Gb eMMC CM3+.  It's working!

On my Mac, I basically followed https://github.com/raspberrypi/usbboot using a RPi CM3+ Development Kit.  You plug the CM3+ into the DevKit and then plug in USB to your computer.

Code:

git clone --depth=1 https://github.com/raspberrypi/usbboot
cd usbboot
brew install libusb
make
sudo ./rpiboot

After that, you can use the attached CM3 as if it were a SD card, and you can burn a SD image to it.  The process is a lot slower than burning to an SD.

I used the "Freeplay_CM3-and-Zero2_Test_21110201.img.gz" from https://drive.google.com/drive/folders/0...dwp_RqwzsQ and used the Raspberry Pi Imager to burn that file to the CM3+.

If you use a CM3/CM3+ with eMMC, then the SD slot on the Freeplay CM3 is totally useless.  The lines from the SD card will not even connect to the Pi's processor.  You can have an SD in or out, but the Pi will never see it.  The eMMC takes the place of the SD card.

P.S.  The development kit I used is just like this one.  https://www.ebay.com/itm/224775123233  Note that a normal kit from a shop would include actual Compute Module 3, but that eBay listing does not include any actual CM3.
