| This device tree overlay is provided to enable the functionality of the Coral |
| Environmental Sensor Board. |
| |
| For Raspberry Pi platforms: |
| |
| The included EEPROM is already flashed with this overlay. No additional steps are needed. |
| If customization of the blob is desired, dtc is used to compile the overlay: |
| dtc -@ -I dts -O dtb -o coral-enviro-board.dtbo coral-enviro-board.dts |
| |
| It is also possible to overwrite the EEPROM. In order to do this: |
| 1) Short JP1 (a solder bridge) to unlock the EEPROM. |
| 2) Enable I2C0 access (add dtparam=i2c0=on to config.txt in the boot partiton). |
| 3) Rebuild and flash following instructions at https://github.com/raspberrypi/hats/tree/master/eepromutils |
| |
| |
| For Coral platforms: |
| |
| The overlay can be put in the boot folder in order to automatically load on boot. |
| Once added to /boot, modify overlays.txt to add coral-enviro-board |
| (e.g overlays=coral-enviro-board). |
| |
| If customization of the blob is desired, dtc is used to compile the overlay: |
| dtc -@ -I dts -O dtb -o coral-enviro-board.dtbo coral-enviro-board.dts |
