This is probably a simple question, but since I am new to yocto there is a lot to learn…
How do I establish kernel access permissions for the “zeus” kernel so that when my application is up and running, (or an application startup script), can create read/write files for access/updating in the ”/etc” and “/dev” directories ?
In the few cases I do this I am seeing unable to open errors…
Note the same code appears to work correctly under “rocko”…
you have to provide more context to help you more, but usually /dev is populated with devtmpfs during kernel boot. and similarly /etc is mounted early on. So access permissions could be mounting issues perhaps.
