Multiarch support Rock64

[stuartiannaylor]

Update on what I've learned.
a. Used DD to save and restore an SD card image on a Linux Mint laptop. Now have a clone of the tweaked build so I can continue testing the multiarch add-ons. Yippee! The restored card boots up per normal in the Rock64. Took a lot more time than I'm used to with other "cloning" apps. Save of 32GB card took an hour or so. Restoring the 32GB card image took 2-3 hours (not exactly sure, could look at logs but bottom line, took a while). If there are other/more commands I could be using let me know. Thanks.

Save and Restore Linux Rock64 build SD card
 
NOTE: Need running Linux laptop or PC with a card reader.
          Need approximately the same about of space free on the HDD as the card size.
 
1.    lsblk -l or lsblk –fs                                                                 check attached devices.
2.    sudo dd if=/dev/mmcblk0 of=~/stretch-sd.img                        create saved image
3.    Unmount source sd card, remove it.
4.    Insert target sd card.                                                            used same brand, same size card as original build.
5.    sudo dd if=~/stretch-sd.img of=/dev/mmcblk0                        write saved image to different card.
6.    lsblk -l or lsblk –fs                                                                 check attached devices.
7.    Unmount target sd card, remove it.

b. Attempting to save the image from a running Rock64 build to an attached USB HDD. Can't seem to wrap my head around creating an "image" subdir on the usb HDD. Have it partitioned, filesystem created, mounted, but can't seem to create a location on the HDD where the saved DD image will reside. It's something simple, staring me in the face but so far no luck. I used the noob tutorial for adding USB storage but must have messed up somewhere. I'll keep trying.

So sudo mkdir isn't working?
Guess you could just create the directory on the host you where writing images from.

My main clients are windows so winimage http://www.winimage.com/ create windows alternative to dd for both creating and writing image files.

Also noticed with rufus that in the new version  2.17 now has a 2 modes for writing images iso & dd mode.
dd mode should work for the rock64 but prob will use winimage and vhds after that or stick with etcher for initial images.

Also I managed to get one of these and it does seem to be an omission in the Pine store.

I did get an eMMC module and I know you can write by adding jumpers & stuff but this is so much easier & handier.
I got my eMMC module from the store but had to get the reader from https://www.odroid.co.uk/ who usually only supply with the eMMC but where king enough to accommodate.
