Updating the ROMFS File System
------------------------------
The content on the nsh_romfsimg.h header file is generated from a sample
directory structure. That directory structure is contained in the binary
file etc.tar.gz and can be modified per the following steps:
NOTE: It is not advised to do this under Windows. Windows will end up
changing the file permissions so the files under /etc will have executable
permissions.
1. Unpack the directory structure:
tar zxf etc.tar.gz
2. Make modifications as desired.
3. Create the new ROMFS image.
genromfs -f romfs_img -d etc -V SimEtcVol
4. Convert the ROMFS image to a C header file
xxd -i romfs_img >nsh_romfsimg.h
5. Edit nsh_romfsimg.h, mark both data definitions as 'const' so that
that will be stored in FLASH.
6. Re-package the modified /etc directory
tar cvf etc.tar etc
gzip etc.tar
directory structure. You can directly modify files under etc/ folder,
The build system will regenerate nsh_romfsimg.h automatically.
See the sim/nsh configuration for an example of the use of this file
system.
