clone the project into the desired working directory;
git clone https://github.com/stm32-hotspot/DRC02_IIoT_GreenGrass_Gateway.git DESIRED_WORKING_DIRECTORY cd DESIRED_WORKING_DIRECTORY/projects/drc02-greengrass
and execute the script found in the DESIRED_WORKING_DIRECTORY/projects/drc02-greengrass folder;
. drc02-greengrass.sh
This will create the needed repo as well as retrieve additional required layers.
At the end of this scripts execution you will have the directory structure below;
WORKING_DIRECTORY_NAME
├── layers
│ ├── meta-amefae-connectivity layer for setting up wireless connectivity
│ └── meta-amefae-greengrass layer with rules for greengrass inclusion
└── projects
└── drc02-greengrass
└── working Temp directory with the main yocto build checkout
├── downloads used for many of the build downloads
├── drc02-gg This is the directory set up by the script as the target of the build
└── sources layers from the platform providers
Anything below "working" can be considered a temporary file.
Important points to make sure you are aware of
- currently using the core-image-minimal target
- the output files can be written to an SD card using the command
. unxz -c core-image-minimal-dh-stm32mp1-dhcom-drc02.wic.xz | sudo dd of=/dev/SDCARD_DEVICE bs=1M iflag=fullblock oflag=direct conv=fsync status=progress
- By default the boot will use internal storage, you must change this during the boot process
. power on board, hit a key when the message "Hit any key to stop autoboot: 1" is seen
. issue the command "env set boot_targets mmc0 mmc1 mmc2 usb pxe"
. issue the command "boot"
- currently the default operation of the bluetooth / wifi module is to operate in only Wifi mode
. in /etc/modprobe.d/rsi_sdio.conf change the mode to 13 to enable bluetooth operation
. echo "options rsi_sdio dev_oper_mode=13" > /etc/modprobe.d/rsi_sdio.conf
- login as root, no password
Steps to run GG IDT
- build and write to SD Card - echo "ggc_user ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers - mkdir /home/ggc_user - chown ggc_user:ggc_group /home/ggc_user - change password for ggc_user : passwd ggc_user - modify /etc/passwd : ggc_user:x:996:996::/home/ggc_user:/bin/sh - from HOST : ssh-keygen -f "/home/user/.ssh/known_hosts" -R "10.0.0.xxx" - from HOST : ssh-copy-id ggc_user@10.0.0.xxx - confirm there is a file on the target : /home/ggc_user/.ssh/authorized_keys - confirm you can ssh to the target : ssh ggc_user@10.0.0.xxx - confirm sudo privledges - docker run hello-world
