Help to kill read only system
#1
While doing too many things to once, I mistakenly managed to burn Zorin Lite OS onto the eMMC of my Tinkerboard S… Now Etcher does not recognize the eMMC so I am unable to reinstall the Tinker OS to it. I am able to boot the Tinker OS via a micro SD card. I have tried to remove Zorin using both File Manager and LX Terminal but I lack the proper magic incantation to defeat a "READ ONLY SYSTEM". Any help would be most appreciated.

BTW.
Armbian has support for UMS and come with better support than TinkerOS or its derivatives which are usually without any support. Like you just experienced.

igorpec... Thanks again for the link you sent me. I tried several of the cures it put forward but none worked for me... However it was very helpful in showing me why Etcher was unable to recognize the EMMC and why I was unable to burn a Tinker OS to it... After some more searching I found this link... https://tinkerboarding.co.uk/forum/attac...hp?aid=353... After several failed attempts I was able cure my problem.

I burned a copy of a Linaro Tinkerboard OS to a mini SD card and put it into the SD slot of the Tinkerboard. I booted the board and went into Terminal. I determined that the SD card was called mmcblk1 and the EMMC is called mmcblk0. I entered this bit of code and hit ENTER.

# dd if=/dev/mmcblk1 of=/dev/mmcblk0 bs=4M conv=notrunc,noerror,sync status=progress


After about ten minutes the Tinkerboard transfered the OS from the SD card to the EMMC, overwriting the Zorin OS. I removed the SD card and am now able to boot the Tinkerboard OS from the EMMC and Etcher is able to recognize the Tinkerboard as a drive to burn to.

So thanks for help...

Now you can also flash Armbian directly to your eMMC and downgrade back to TinkerOS if you like ...
