Hi,
I would like to protect my SD card from being damaged by making the root fs read only to no avail so far. I tried some receipts from this forum, none of them worked with the latest pre-built SD image from Nvidia. Moreover, applying the patches to an older version of JP did NOT create me a RO fs, instead I still was able to write to /dev/root after reboot (see overlayfs for Jetson - #12 by juerg)
What am I missing?
