| This device tree overlay is provided to enable the functionality of the Coral |
| Environmental Sensor Board. It is already included on the HAT EEPROM included |
| with the board. |
| |
| If customization of the blob is desired, dtc is used to compile the overlay: |
| dtc -@ -I dts -O dtb -o coral-enviro-board-overlay.dtbo coral-enviro-board-overlay.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 |
