Flashing full image to eMMc with a mSD card to eCMM adapter

[pytheas]

FWIW
I failed to order the Pine USB Adapter for eMMC Module when ordering my Rock64.

Due to the shipping rate to Europe, ordering it later from Pine was  not an option.

So I turned to the Odroid microSD to eMMc adapter sold by Amazon at a more reasonable shipping rate.

Using Win32DiskImager, I uploaded the 32 GB microSD Bionic full image I have been using to my Windows 10 PC .
I then formatted (Full Erase (which failed), then Quick Erase) the Pine 64 GB eMMc (using the microSD adapter fitted into an SD adapter) with SDFormatter.
Last, I used Etcher to flash the Bionic image back to the eMMC card (using the same setup).
Pressing the eMMC in position on the Rock64, booting went without a hitch. ..
BTW, you immediately notice that boot time is reduced...

PS I used gparted to fill the 64GB module...
