Multiarch support Rock64

The Win32 Disk Imager method seems to be the least volatile so I'll try that first.

Actually, Win32 Disk Imager is the most troublesome ;  which is why we recommend Etcher.  Words to the wise.

Win32 Disk Imager on my PC didn't work as it (windows) doesn't recognize the SD card. Not sure if it's because of writing the linux image to it or booting it up in the Rock64 or something fubar'd in my windows pc. I've used Win32 Disk imager to write ISOs in the past so I'm confident that's not the culprit. It's on my list of things to test.
1. Format the SD card in windows PC.
2. Remove it, remount it - shouldn't be any issue in the PC. If so, it's my windows PC that's needing attention.
3. Write an image using Etcher on the PC.
4. Eject the card via "safely remove hardware and media" - don't need yanking the card to cause a problem.
5. Put the card back into the PC. Any errors?
6. If no errors, eject it again.
7. Fire up the linux build in the Rock64. Log in per usual.
8. Shutdown and remove the SD card.
9. Put SD card in the windows PC - my money's on windows choking on it. Wagers anyone????? If that's the case, that will tell me booting the image in the Rock64, while great, means I can't use a windows PC to back up the card.
Another test on my list is to:
9. Rather than using the windows PC, put the card in a linux PC (have a Toshiba laptop running Mint) and see if I can read the card - my money's on yes. If so, I can use the Mint laptop to save the image using DD I presume.
Make sense? Waste of time because others have already done this and know the answers? 

Yeah I am same always used Win32 Disk Imager with the Pi but can not say until I get my Rock.
Maybe with The Uboot & the SPI flash its going to be a complete PIA and maybe someone will explain.
Could well be the partition layout just dunno until I try but apparently its on its way.

Might find DD is the same but prob need to see why etcher can write Iso's and is preferred its still a cul-de-sac as you want to make an ISO.
Should so some reading on etcher.
