This README discusses issues unique to NuttX configurations for the
|
|
|
|
|
Particle.io Photon board featuring the STM32F205RG MCU.
|
|
|
|
|
The STM32F205RG is a 120 MHz Cortex-M3 operation with 1Mbit Flash
|
|
|
|
|
memory and 128kbytes. The board includes a Broadcom BCM43362 WiFi.

Selecting the Photon board on NuttX
|
|
|
|
|
===================================
|
|
|
|
|
|
|
|
|
|
NOTICE: We will not discuss about toolchains and environment configuration
|
|
|
|
|
here, please take a look at STM32F4Discory board README or other STM32 board
|
|
|
|
|
because it should work for Photon board as well.
|
|
|
|
|
|
|
|
|
|
Let us to consider that you cloned the nuttx and apps repositories, then
|
|
|
|
|
follow these steps:
|
|
|
|
|
|
|
|
|
|
1) Clear your build system before to start:
|
|
|
|
|
|
|
|
|
|
$ make apps_distclean
|
|
|
|
|
$ make distclean
|
|
|
|
|
|
|
|
|
|
2) Enter inside nuttx/tools and configure to use the Photon board:
|
|
|
|
|
|
|
|
|
|
$ cd nuttx
|
|
|
|
|
$ cd tools
|
|
|
|
|
$ ./configure.sh photon/wlan
|
|
|
|
|
|
|
|
|
|
Now please return to root of nuttx/ directory:
|
|
|
|
|
|
|
|
|
|
$ cd ..
|
|
|
|
|
|
|
|
|
|
Configuring NuttX to use your Wireless Router (aka Access Point)
|
|
|
|
|
================================================================
|
|
|
|
|
|
|
|
|
|
Since you are already in the root of nuttx/ repository, execute
|
|
|
|
|
make menuconfig to define your Wireless Router and your password:
|
|
|
|
|
|
|
|
|
|
$ make menuconfig
|
|
|
|
|
|
|
|
|
|
Browser the menus this way:
|
|

|
|
|
NSH Library --->
|
|
|
|
|
Networking Configuration --->
|
|
|
|
|
WAPI Configuration --->
|
|
|
|
|
(myApSSID) SSID
|
|
|
|
|
(mySSIDpassphrase) Passprhase
|
|
|
|
|
|
|
|
|
|
Replace the SSID from myApSSID with your wireless router name and
|
|
|
|
|
the Passprhase with your WiFi password.
|
|
|
|
|
|
|
|
|
|
Exit and save your configuration.
|
|
|
|
|
|
|
|
|
|
Finally just compile NuttX:
|
|
|
|
|
|
|
|
|
|
$ make
|
|
|
|
|
|
|
|
|
|
Flashing NuttX in the Photon board
|
|
|
|
|
==================================
|
|
|
|
|
|
|
|
|
|
Connect the Photon board in your computer using a MicroUSB cable. Press and
|
|
|
|
|
hold both board's buttons (SETUP and RESET), then release the RESET button,
|
|
|
|
|
the board will start blinking in the Purple color, waiting until it starts
|
|
|
|
|
blinking in Yellow color. Now you can release the SETUP button as well.
|
|
|
|
|
|
|
|
|
|
1) You can verify if DFU mode in your board is working, using this command:
|
|
|
|
|
|
|
|
|
|
$ sudo dfu-util -l
|
|
|
|
|
dfu-util 0.8

Serial console configuration
|
|
|
|
|
============================
|
|
|
|
|
|
|
|
|
|
Connect a USB/Serial 3.3V dongle to GND, TX and RX pins of Photon board.
|
|
|
|
|
Then use some serial console client (minicom, picocom, teraterm, etc) confi-
|
|
|
|
|
gured to 115200 8n1 without software or hardware flow control.
|
|
|
|
|
|
|
|
|
|
Reset the board and you should see NuttX starting in the serial.
