I remember having seen similar problems when I tried using the eMMC last
year.
I also used crochet and the copy script, but IIRC ended when it didn't boot.
Details should be on this list somewhere.

After running it, i checked the MSDOS and UFS partitions and it seems they are OK. But, after removing the SD card and trying to boot from the internal eMMC i just see ???C??????s coming out slowly of the serial console, nothing else is happening. Putting in the SD card and all runs well again.
