VSN Board Support Package, for the NuttX, Uros Platise <uros.platise@isotel.eu>
|

===============================================================================
|
||||
http://www.netClamps.com
|
||||
|
||||
The directory contains start-up and board level functions.
|
||||
Execution starts in the following order:

is set. It must be set for the VSN board.
|
||||
|
||||
- boot, performs initial chip and board initialization
|
||||
- ...
|
||||
- nsh, as central application last.
|
||||
- sched/os_bringup.c then calls either user_start or exec_nuttapp()
|
||||
with application as set in the .config
|
||||
|
||||
|
||||
Naming throughout the code
|
||||
==========================
|
||||
|
||||
- _init(): used to be called once only, after powerup, to perform board
|
||||
initialization
|
||||
- _start() or called via FS _open(): starts peripheral power, puts it
|
||||
into operation
|
||||
- _stop() or called via FS _close(): opposite to _start()
|
||||
|
||||
|
||||
System notifications (a sort of run-levels)
|
||||
===========================================
|
||||
|
||||
On the VSN, NSH represents the core application as it supports scripts
|
||||
easily adaptable for any custom application configuration. NSH is
|
||||
invoked as follows (argument runs a script from the /etc/init.d directory):
|
||||
|
||||
- nsh init: on system powerup called by the NuttX APP_START
|
||||
|
||||
TODOs:
|
||||
|
||||
- nsh xpowerup: run on external power used to:
|
||||
- try to setup an USB serial connection
|
||||
- configure SLIP mode, internet
|
||||
- start other internet services, such as telnetd, ftpd, httpd
|
||||
|
||||
- nsh xpowerdown: run whenever USB recevied suspend signal or
|
||||
external power has been removed.
|
||||
- used to stop internet services
|
||||
|
||||
- nsh batdown: whenever battery is completely discharged
|
||||
|
||||
|
||||
Compile notes
|
||||
===============================
|
||||
|
||||
To link-in the sif_main() utility do, in this folder:
|
||||
- make context TOPDIR=<path to nuttx top dir>
|
||||
|
||||
This will result in registering the application into the nuttapp.

* STDOUT Coding 16-bit (little endian):
