Make Arduino Applications for ODROID-GO

git clone https://github.com/othercrashoverride/odroid-go-firmware.git -b factory
cd odroid-go-firmware/tools/mkfw
make

After you run Arduino IDE, select compilation, File → Preferences → Show verbose output during.

You can see the path of Arduino binary you compiled on the log.
Copy the binary into mkfw folder.

You can make a tile image that appears in the App menu.

sudo apt install ffmpeg
ffmpeg -i 86x48px-Arduino_Logo.png -f rawvideo -pix_fmt rgb565 tile.raw

./mkfw test tile.raw 0 16 1048576 app Hello_World.ino.bin

The output is firmware.fw. Change the name.

mv firmware.fw Hello_World.fw

Insert your SD card to your ODROID-GO.

We will take a Weather-Station as an example.

First, we will make a data folder into a binary.
And the two binary files(data folder and firmware) will be a .fw file with mkfs.

Get the mkspiffs at this and then, run the command.

mkspiffs -c ./data -b 4096 -p 256 -s 0x100000 spiffs.bin

For detail on command, https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/storage/spiffs.html#tools

./mkfw test tile.raw 0 16 1048576 app Weather_Station.ino.bin 1 130 1048576 "spiffs" spiffs.bin
cp firmware.fw Weather_Station.fw

The SPIFFS partition information is derived from here: https://github.com/espressif/esp-idf/blob/master/components/spi_flash/include/esp_partition.h

Copy the firmware.fw to your SD card “odroid/firmware/ folder
