I recently purchased Mini Router/PC with Raspberry Pi Compute Module 4, Dual Gigabit Ethernet NICs, 4GB RAM/32GB eMMC, Support OpenWRT. I was able to power it up and ssh in as root, however when I try to set a password, I get an error saying…
passwd: /etc/passwd: Read-only file system
passwd: can’t update password file /etc/passwd
My research thus far has not yielded any solutions that work (e.g. remounting, mtd, etc…).
The only other solution that I haven’t tried yet is re-flashing the OpenWRT image on to the RPi’s eMMC. Before I crack the box and do that, I thought I would see if anyone might point out something obvious that I’ve missed.
