Hi, apologies if this is a really silly question but if you used your product to encrypt the system partition of a raspberry Pi and then the unit was stolen could you bypass the encryption/protection by doing the following
1) Remove the SD card and put in another computer
2) Edit the cmdline.txt and add init=/bin/sh to the end of the line.
3) add a new blank file called "ssh" in the boot partition, this enables SSH if you want
4) Put back into the Pi leaving the Zymbit connected, add keyboard/monitor and boot.
5) At the prompt type "mount -rw -o remount /"
6) type passwd pi
7) Enter new password
8) Thats it, you've in and the data is accessible because the Zymbit board is still connected.
Im guessing that is why you have the tamper protection which will disable the Zymbit but I can't find the documentation to this and it doesnt look like its available on the standard product, only OEM. I did read that you will have a reset function for this but concerned this could be used by the person who stole the device.
I presume the Zymbit will rely on the onboard coin battery to detect tampering in order to disable the product else someone could simply remove the power and break into it.
Could you please provide advice and ETA when it'll be in your standard product plus documentation.
