Really don’t understand how you make it boot RO, but suggest to open another topic to get issue root caused and resolved.
I didn’t make it. And I will not open yet another topic on this, it will not work.
Regarding the SD protection, as the reply at Make Jetson Nano SD /dev/root read-only, that’s not supported, but for eMMC module only.
I’m sorry, I don’t believe that. As @linuxdev stated each Linux rootfs can be made RO. But obviously not your’s.
Please help to reply back to each topic you created, then our team can help to move it forward.
For what topic do you miss my response? For me it is quite the other way around.
And to let you know how I bricked the Nano: I just used your SDK manager and “managed” to kill it:
In the middle of the flash the Nano booted and that was it.
