Other Parts Discussed in Thread: AM625
I did some experimentations to see if it's possible to clone my SD root fs to the eMMC root fs.
Why? Because I needed some software that do not exist on the base image for eMMC, as the default image did not work for my EVM.
Good news: It's possible.
Bad news: A single non-essential folder is causing issues.
After the copy process runs for a while and gets to the folder /usr/bin/, it suddenly fails with "running CQE recovery".
After some digging, I found out that the specific file/folder it fails at is /usr/bin/SGX, which seems to be non-essential.
By excluding that folder, pretty much all other files and folder can be copied.
TI might need to have a look at why this is happening, as I suspect that this may cause issues elsewhere as well.
Here is the error report:
