Option	Argument	Note
-g	path/to/GCC-archive-path	GCC archive path
-s	path/to/SDK-archive-path	Prebuilt SDK archive path

For using local source code

Option	Argument	Note
-S	path/to/spresense-sdk-path	Local Spresense SDK build root path
-v	Board_variant	Target board variant (default:spresense)
-c	spresense or spresense_sub	Target SDK configuration (default: spresense)
-k	release or debug	Target kernel configuration (default: release)
-M	"SDK" or "Kernel" or "SDK/Kernel"	Manual configuration by menuconfig
-G	"SDK" or "Kernel" or "SDK/Kernel"	Manual configuration by gconfig
-Q	"SDK" or "Kernel" or "SDK/Kernel"	Manual configuration by qconfig
-i	-	Do not change Kernel/SDK configuration

Other option

Option	Argument	Note
-H	Windows or Linux64 or Mac	Arduino IDE Host OS
-p	-	No network access option
-h	-	Show help

Example

Export Spresense SDK prebuilt binary for MainCore/Debug:Disabled from local repository.

$ ./tools/prepare_arduino.sh -S path/to/spresense -p

Export Spresense SDK prebuilt binary for MainCore/Debug:Enabled from local repository.

$ ./tools/prepare_arduino.sh -S path/to/spresense -k debug -p

Export Spresense SDK prebuilt binary for SubCore/Debug:Disabled from local repository.

$ ./tools/prepare_arduino.sh -S path/to/spresense -c spresense_sub -k subcore-release -p

Export Spresense SDK prebuilt binary for SubCore/Debug:Enabled from local repository.

$ ./tools/prepare_arduino.sh -S path/to/spresense -c spresense_sub -k subcore-debug -p

Export Spresense SDK prebuilt binary for MainCore/Debug:Disabled from local repository with configuration change.

$ ./tools/prepare_arduino.sh -S path/to/spresense -M SDK/Kernel -p

• Menu configuration will open twice as NuttX Configuration and SDK configuration

Creating Arduino boards manager local install package

To create a Arduino boards manager files for manual installation simply type:

$ make

This command will generate the following files:

out/package_spresense_local_index.json
out/staging/spresense-v*.*.*_local.tar.gz
out/staging/spresense-tools-v*.*.*_local.tar.gz
out/staging/spresense-sdk-v*.*.*_local.tar.gz

Manual install

1. Copy out/staging into <Arduino15> directory.
2. Set package_spresense_local_index.json URL into Additional Boards Manager URLs in Arduino IDE.
3. Install local spresense board package by Boards Manager in Arduino IDE as same as official package.

<Arduino15>:

• Windows: %userprofile%\AppData\Local\Arduino15
• macOS: ~/Library/Arduino15
• Ubuntu: ~/.arduino15

package_spresense_local_index.json URL:

file://path/to/out/package_spresense_local_index.json
