I have a question about this step.
"- Once those are installed plugin your Freeplay board with the CM3 slotted to your Windows Machine"
Did you use something like a "USB A to A" cable to plug into a USB-A port on your computer or did you plug in to a USB-C port on your computer using a "USB C to A" cable?
Now, for your question.
"Why does the CM3 board only use the lite versions of the CM3 module? I think it has to do with the pin out pointing to the SD card and not the on-board eMMC flash.
I found a few threads here stating that you can alter the board physically to get it to work but that's a pain."
The eMMC that would be on-board a non-lite CM3 uses the same "pins" that the SD card would use. So, it's an either/or sort of thing. You can't have a SD card inserted when using eMMC.
Yes, there is a list of super tiny resistors that you can move on the Compute Module 3 itself that can cause it to disable its onboard eMMC and act like a Lite. We have successfully tested this, but I would not recommend it to anyone.
So, your two options for using a non-lite is to move around the resistors (which we definitely do NOT recommend) or doing like you did and then never use the SD slot.
Our recommendation is to still use the CM3 Lite or CM3+ Lite, but I do understand that they are hard to purchase at the moment.
I used USB A to USB A.
Thanks for your reply!
