I’m at a disadvantage with HA on the N2; my experience is limited to a different application. When you use the
ls command, do you see
/dev/mmcblk0 listed? Can I assume the flash process doesn’t even start?
As an aside, it looks as if there have been upgrades with the Petitboot bootloader. That said, I’m not sure it’s the issue, or if an upgrade will even help. Perhaps you need a recovery image to get it to work.
I suggest two potential ways of getting help if the above links don’t help:
The preferred way is to look through the issues on GitHub and see if there’s anything with the same problem signature. If you don’t see something similar enough, write up a new issue. Hopefully, someone with relevant experience (e.g. @agners) will respond and point you in the right direction.
Here’s a similar issue: https://github.com/home-assistant/operating-system/issues/771
The second path is to go to Hardkernel for help via their forum:
Either approach requires having an account.
