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/

/etc/init.d/rcS is the start-up script; /etc/passwd is a the password
|
||
|
|

|
||
|
|
|
||
|
|
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
|
