Hi all,

I have flashed the latest OS into the internal memory of the Tinker Edge R. I would please like to know how to clone the image file into other boards.

thank you in advance

hello @marco@bigsis.tech, 

there are different ways and tools to copy/ dump the os either from emmc or sdcard. the easiest way i can think of is to use dd command, usually i clone the os to sdcard and use balena etcher to flash other boards; if your two tinker edge r's are conencted to the same pc, you can direct the path to the board that you're going to flash. 

1. insert a sdcard, using

lsblk 

to check its path, in my case it's /dev/mmcblk0

2. clone the os

sudo dd if=/dev/mmcblk0 of=/dev/sda/emmc.img conv=noerror,sync

or

sudo dd if=/dev/mmcblk1 of=/dev/mmcblk0 bs=4M

here i clone the whole system and it takes around 18 minutes

3. once it's done, you can use the sdcard to flash another tinker edge r under ums mode, using tools such as balena etcher
