======
|
||||
|
||||
This directory contains logic to support a custom ROMFS start-up script.
|
||||
This startup script is used by by the NSH when it starts provided that
|
||||
CONFIG_NSH_ARCHROMFS=y. The script provides a ROMFS volue that will be
|
||||
mounted at /etc and will look like this at run-time:
|
||||
|
||||
NuttShell (NSH) NuttX-7.13
|
||||
This is the message of the day
|
||||
nsh> ls -Rl /etc
|
||||
/etc:
|
||||
dr-xr-xr-x 0 .
|
||||
dr-xr-xr-x 0 init.d/
|
||||
-r--r--r-- 39 passwd
|
||||
/etc/init.d:
|
||||
dr-xr-xr-x 0 ..
|
||||
-r--r--r-- 110 rcS
|
||||
nsh>
|
||||
|
||||
/etc/init.d/rcS is the start-up script; /etc/passwd is a the password
|
||||
file. It supports a single user:
|
||||
|
||||
USERNAME: admin
|
||||
PASSWORD: Adminstrator
|
||||
|
||||
This directory structure is contained in the binary file etc.tar.gz and
|
||||
can be modified per the following steps:
|
||||
|
||||
1. Unpack the directory structure:
|
||||
|
||||
tar zxf etc.tar.gz
|
||||
|
||||
2. Make modifications as desired.
|
||||
|
||||
3. Create the new ROMFS image.
|
||||
|
||||
genromfs -f romfs_image -d etc -V SimEtcVol
|
||||
|
||||
4. Convert the ROMFS image to a C header file
|
||||
|
||||
xxd -i image >nsh_romfsimg.h
|
||||
|
||||
5. Re-package the modified /etc directory
|
||||
|
||||
tar cvf etc.tar etc
|
||||
gzip etc.tar
|
||||
|
||||
See the sim/nsh configuration for an example of the use of this file
|
||||
system.
