+================================
+1. In wd_start.c file, in function wd_expiration(), typecasting is done when the signal handler nxsig_timeout() is invoked.
+2. In rtc.c, (drivers/timers/rtc.c) file, in function rtc_periodic_callback(), alarminfo->active = false is commented.
+The reason being, periodic interrupt should not be disabled. Uncommenting the above mentioned line (alarminfo->active = false), will make the periodic interrupt come only once.

+  Overview
+  --------
+  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 volume that will be
+  mounted at /etc and will look like this at run-time:
+
+    NuttShell (NSH) NuttX-8.2
+    nsh> ls -l /etc
+    /etc:
+     dr-xr-xr-x       0 .
+     -r--r--r--      20 group
+     dr-xr-xr-x       0 init.d/
+     -r--r--r--      35 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
+
+    nsh> cat /etc/passwd
+    admin:8Tv+Hbmr3pLddSjtzL0kwC:0:0:/
+
+  The encrypted passwords in the provided passwd file are only valid if the
+  TEA key is set to:  012345678 9abcdef0 012345678 9abcdef0.  Changes to either
+  the key or the password word will require regeneration of the nsh_romfimg.h
+  header file.
+
+  The format of the password file is:
+
+    user:x:uid:gid:home
+
+  Where:
+    user:  User name
+    x:     Encrypted password
+    uid:   User ID (0 for now)
+    gid:   Group ID (0 for now)
+    home:  Login directory (/ for now)
+
+  /etc/group is a group file.  It is not currently used.
+
+    nsh> cat /etc/group
+    root:*:0:root,admin
+
+  The format of the group file is:
+
+    group:x:gid:users
+
+  Where:
+    group:  The group name
+    x:      Group password
+    gid:    Group ID
+    users:  A comma separated list of members of the group
+
+  /etc/init.d/rcS should have the following contents : 
+  vi rcS
+  echo "This is NuttX"
+
+  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 etc/ directory and can be modified per the following steps:
+
+
+    1. Change directory to etc/:
+
+       cd etc/
+
+    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.

+================================
+1. In wd_start.c file, in function wd_expiration(), typecasting is done when the signal handler nxsig_timeout() is invoked.
+2. In rtc.c, (drivers/timers/rtc.c) file, in function rtc_periodic_callback(), alarminfo->active = false is commented.
+The reason being, periodic interrupt should not be disabled. Uncommenting the above mentioned line (alarminfo->active = false), will make the periodic interrupt come only once.

+README
+======
+
+  Overview
+  --------
+  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 volume that will be
+  mounted at /etc and will look like this at run-time:
+
+    NuttShell (NSH) NuttX-8.2
+    nsh> ls -l /etc
+    /etc:
+     dr-xr-xr-x       0 .
+     -r--r--r--      20 group
+     dr-xr-xr-x       0 init.d/
+     -r--r--r--      35 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
+
+    nsh> cat /etc/passwd
+    admin:8Tv+Hbmr3pLddSjtzL0kwC:0:0:/
+
+  The encrypted passwords in the provided passwd file are only valid if the
+  TEA key is set to:  012345678 9abcdef0 012345678 9abcdef0.  Changes to either
+  the key or the password word will require regeneration of the nsh_romfimg.h
+  header file.
+
+  The format of the password file is:
+
+    user:x:uid:gid:home
+
+  Where:
+    user:  User name
+    x:     Encrypted password
+    uid:   User ID (0 for now)
+    gid:   Group ID (0 for now)
+    home:  Login directory (/ for now)
+
+  /etc/group is a group file.  It is not currently used.
+
+    nsh> cat /etc/group
+    root:*:0:root,admin
+
+  The format of the group file is:
+
+    group:x:gid:users
+
+  Where:
+    group:  The group name
+    x:      Group password
+    gid:    Group ID
+    users:  A comma separated list of members of the group
+
+  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 etc/ directory and can be modified per the following steps:
+
+
+    1. Change directory to etc/:
+
+       cd etc/
+
+    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.
