================================================================
|
|
|
|
|
|
|
|
|
|
$ make menuconfig
|
|

(myApSSID) SSID
|
|
|
|
|
(mySSIDpassphrase) Passprhase
|
|
|
|
|
|
|
|
|
|
Replace the SSID from myApSSID with your wireless router name and
|
|
|
|
|
the Passprhase with your WiFi password.
|
|
|
|
|
|
|
|
|
|
Exit and save.
|
|
|
|
|
|
|
|
|
|
Finally just compile NuttX:
|
|
|
|
|
|
|
|
|
|
$ make
|
|
|
|
|
|
|
|
|
|
Programming Flash
|
|
|
|
|
=================
|
|
|
|
|
|
|
|
|
|
Flash memory can be programmed by stlink toolset
|
|
|
|
|
(https://github.com/stlink-org/stlink) and ST-LINK V2 programmer
|
|
|
|
|
(via SWD interface) as follows:
|
|
|
|
|
|
|
|
|
|
$ sudo st-flash write nuttx.bin 0x8000000
|
|
|
|
|
|
|
|
|
|
NSH via telnet
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
After you successfully downloaded nuttx.bin, reset the board and it
|
|
|
|
|
automatically connects to the corresponding wifi AP. You may login
|
|
|
|
|
your router to see its IP address. Assume that it's 192.168.1.111
|
|
|
|
|
|
|
|
|
|
Open a terminal on your computer and telnet your EMW3162 board:
|
|
|
|
|
|
|
|
|
|
$ telnet 192.168.1.111
|
|
|
|
|
Trying 192.168.1.111...
|
|
|
|
|
Connected to 192.168.1.111.

|
|
|
|
|
============================
|
|
|
|
|
|
|
|
|
|
Connect a USB/Serial 3.3V dongle to GND, TXD and RXD pins of EMW3162 board.
|
|
|
|
|
Then use some serial console client (minicom, picocom, teraterm, etc) confi-
|
|
|
|
|
gured to 115200 8n1 without software or hardware flow control.
|
|
|
