I received my JingPad A1 last week. I’m interested in running other OSes on the JingPad. I know that one user got Ubuntu Touch running (presumably through their plug-in installer.)
I’m experienced with Linux, but not super-familiar with ARM devices. I’ve flashed a few boot ROMs on Android devices over the years. I’ve done some pretty low-level work with Raspberry Pis (getting OpenBSD running required attaching to the serial console, for example.)
I’m just not 100% sure where to start with the JingPad.
My biggest questions are:
- How do I access the boot loader/GRUB on boot?
- How do I take an image of the running device?
- How do I apply an image to the device’s storage?
I imagine it’s similar to what you’d need to do with an Android device, so I’ll probably start running down that road on my own, but any guidance would be lovely.
Basically, I want to be able to try out other OSes and then get back to stock JingOS when I’m done, but I’m not sure where to start. Happy to dig in and document though.
