I am using Rock4C+.
I used to use it normally, but (perhaps I made a mistake in the setting of rsetup…) suddenly it stopped working.
Even if I burn the OS to a micro SD card, after turning on the power, the blue lamp blinks, but the boot screen does not appear on the monitor.
Instead, the micro SD card has been wiped from everything from the OS, and instead only one file “config.txt” remains.
This file has the following description:
rsetup config file
Configurations here will be applied on every boot.
Additionally you can create
after.txt in this folder.
They will run before and after this file, and will be deleted in the end.
This makes them suitable for one-time setup.
Please let me know if you know what kind of setting should be done for normal use as before.
