Information

The Samsung ARTIK™ 055S Module is a highly integrated module for secure Internet of Things (IoT) devices that require Wi-Fi®. It is based on an ARM® Cortex® R4 core with on-chip memories, a complete 2.4GHz Wi-Fi® Phy, MAC layer processing, a large complement of standard digital buses, a PUF-based security system and power management. The module is packaged with additional external Flash memory, a hardware Secure Element and a single integrated 2.4GHz structural antenna. Aimed especially at power-sensitive devices needing Wi-Fi®, the ARTIK055S Module provides excellent performance in a variety of environments, with a feature set tailored specifically for IoT end nodes.

MemoryMap

8MB is allocated to the SPI Flash area. 1280 KB is prepared for operation in SRAM. Here is the physical memory address, see [here].

Configuration Sets

audio

This can be used to test audio functionality.

nettest

This can be used to test network functionality.

Environment Set-up

On Chip Debugger installation

OpenOCD is used to program and debug.

OpenOCD v0.10.0 is recommended and can be installed like below, but pre-built OpenOCD binaray on tools/openocd/linux64(or 32) can be used without installing.

sudo apt-get build-dep openocd
git clone --depth 1 -b v0.10.0 https://git.code.sf.net/p/openocd/code openocd-code
cd openocd-code
./bootstrap
./configure
make
sudo make install

Add USB device Rules

This is an optional environment.
But as ARTIK is connected through USB, some operation like programming of binary can't be worked without this configuration.

  1. Make a file named 99-<anyname>.rules.
  2. Add below contents at above file.
SUBSYSTEMS=="usb",ATTRS{idVendor}=="0403",ATTRS{idProduct}=="6010",MODE="0666" RUN+="/sbin/modprobe ftdi_sio" RUN+="/bin/sh -c 'echo 0403 6010 > /sys/bus/usb-serial/drivers/ftdi_sio/new_id'"
  1. Place the above file in /etc/udev/rules.d folder with sudo permission.
  2. Reboot your system.

How to program a binary

There are two methods, using OpenOCD or script.

After building Tizen RT, follow below steps at $TIZENRT_BASEDIR/os folder.

TIZENRT_BASEDIR was set at [Getting the sources] tab of Quick Start.

Using download script

make download ALL

This makes complete set of binaries programmed.

Using OpenOCD

This is used to program a partial binary.

Export 'OPENOCD_SCRIPTS' to environment variable.

export OPENOCD_SCRIPTS=$TIZENRT_BASEDIR/build/tools/openocd

At first, programming the complete set of binaries are needed.

ARTIK055S

../build/configs/artik05x/tools/codesigner/artik05x_AppCodesigner ../build/configs/artik05x/tools/codesigner/rsa_private.key ../build/output/bin/tinyara_head.bin

openocd -f artik05x.cfg -s ../build/configs/artik05x/scripts -c ' \
    flash_write bl1    ../build/configs/artik055s/bin/bl1.bin;  \
    flash_write bl2    ../build/configs/artik055s/bin/bl2.bin;         \
    flash_write sssfw  ../build/configs/artik055s/bin/sssfw.bin;       \
    flash_write wlanfw ../build/configs/artik055s/bin/wlanfw.bin;      \
    flash_write os     ../build/output/bin/tinyara_head.bin-signed;   \
    exit'

Once the complete binaries are successfully programmed, each partition can be updated separately with new one.

openocd -f artik05x.cfg -s ../build/configs/artik05x/scripts -c ' \
    flash_write os ../build/output/bin/tinyara_head.bin-signed; exit'

Factory Reset

If you can not boot normally, you can change os to the initial version. This is possible if there is an initialization binary in memory.

How to Download the Initialization Binaries

You can download it using OpenOCD. You compress the compiled firmware and download it to the board.

gzip -c tinyara_head.bin-signed > factoryimage.gz
openocd -f artik05x.cfg -s ../build/configs/artik05x/scripts -c ' \
    flash_write factory    ../build/configs/artik055s/bin/factoryimage.gz;      \
    exit'

How to enter initialization mode

When you press the RESET button (SW700) to reboot the Starter Kit, press and hold the 'ARDUINO RESET' button (SW701) for 10 seconds. Enter initialization mode as follows.

ROMFS

Before executing below board-specific steps, execute generic steps, step 1 and step 2.

  1. Modify partition configs and enable the automount config through menuconfig
    Below steps creates ROMFS partition with size 400KB at next of user partition.
    1. Split user partition size from (1400) to (1000, 400) in ARTIK05X_FLASH_PART_LIST 
      Hardware Configuration -> Board Selection -> change values at Flash partition size list (in KBytes)
    2. Append "romfs" at next of smartfs to ARTIK05X_FLASH_PART_TYPE 
      Hardware Configuration -> Board Selection -> append string at Flash partition type list
    3. Append "rom" at next of user to ARTIK05X_FLASH_PART_NAME 
      Hardware Configuration -> Board Selection -> append string at FLash partition name list
    4. Enable the audomount config for romfs 
      Hardware Configuration -> Board Selection -> Automount partitions -> Automount romfs partiton to y
  2. Build Tizen RT and flash a binary using download script
