Please describe your issue below:
I am trying to update an existing VIM3 unit’s onboard EMMC image with a new one. The VIM3 is currently running from the EMMC, and due to various constraints I am trying to avoid requiring the use of an SD card.
Is there a way to either remotely flash a new image to the EMMC? Or do so via a bash script? I would like to insert a USB that has the image on it and have it replace the image that is on the EMMC.
I know there is likely multiple ways of doing this, but my current attempts have been unsuccessful. I tried remotely flashing KRescue using information from this doc while SSH’d into the root… but this failed and has essentially bricked one of my VIM3 units. I currently do not have serial tools to troubleshoot my bricked VIM3 unit, so I am not going to worry about it for the time being.
