Edison Instructions
- Yocto SDK for Edison installed in the host computer. Download here in 'SDK - Cross Compile Tools'
- You will also need Python 3 installed in the host computer (and some additional Python packages)
- python3-jsonschema
- Know how to send files to your Edison board
- Know how to connect to Edison's linux terminal
Once the SDK is installed, it's time to setup a terminal to point to the right tools and paths needed to cross-compile Soletta.
[host]$ source <SDK_PATH>/environment-setup-core2-32-poky-linux
[host]$ export TARGETCC=$CC
[host]$ export TARGETAR=$AR
[host]$ unset PKG_CONFIG_PATH
[host]$ unset PYTHONHOME
Now is necessary to change Soletta's options to match Edison restrictions.
To access the configuration menu:
[host]$ make menuconfig
Go to Core library --> Target platform
If linux-micro is selected, select systemd instead.
- Go to Core Library --> Hardware Options --> Pin Multiplexer and leave only your board selected.
Save the changes and exit the configuration menu.
Now a simple make will build Soletta:
[host]$ make
You can use -j option to compile faster. Check make's manual for more info (man make).
Inside Soletta's directory. First, install soletta in a temporary path:
[host]$ make install DESTDIR=<TMP_PATH>
Pack everything:
[host]$ cd <TMP_PATH>
[host]$ tar cvf soletta.tar *
Copy soletta.tar to Edison root dir and connect to it.
Then:
[root@edison]$ cd /
[root@edison]$ tar xvf soletta.tar
And Soletta should be successfully installed!
To make sure that the installation is ok, copy the sample found in <SOLETTA_SRC_DIR>/src/samples/flow/basics/simple.fbp to Edison
and try to execute:
[root@edison]$ sol-fbp-runner simple.fbp
And check if the output is displayed without errors.
To build it first it is needed to be installed the following on host linux distro: - dfu-util -> tested on version 0.8 and driver 1.0
1- Prepare your workspace:
mkdir my_Edison_Workspace
cd my_Edison_Workspace
2- Get meta-intel-edison layer:
git clone git://git.yoctoproject.org/meta-intel-edison
3- Make link to be able to use make command:
ln -s meta-intel-edison/utils/Makefile.mk Makefile
4- Download all the needed dependencies to BUILD :
make setup
5- Prepare soletta layer to build it with
git clone https://github.com/brunobottazzini/meta-soletta -b edison
echo 'IMAGE_INSTALL_append = " soletta"' >> out/current/build/conf/local.conf
echo 'FULL_PATH_TO_META_SOLETTA' >> out/current/build/conf/bblayers.conf
Replace FULL_PATH_TO_META_SOLETTA to actual path where meta-soletta was cloned.
6- Build Intel Edison Yocto distribution:
make edison-image
7- Flash the board (AS ROOT):
make flash
Edison is not being flashed when running make flash
1- Be aware to use cable USB to micro USB 2.0 on energy supply port otherwise edison will not be found.
2- Use command: lsusb to verify if edison is found when plugging the usb.
3- You may also encounter some problem with dfu-util. If so try updating its drive to the new one.
