Getting Started with RabbitMax Flex IoT and Automation Hat for Raspberry Pi
At the beginning of the month I showed how to assemble RabbitMax Flex, a Raspberry Pi HAT compliant add-on board for Raspberry Pi boards with 40-pin header, that targets IoT and home automation project with its relay, IR transmitter and receiver, I2C headers for sensors, buzzer, RGB LED, and more. Since I’ve already described the hardware, I’ve spend some time this week-end following the user’s guide to play around with the board using a Raspberry Pi 2 board, and try various features.
The user’s manual explains that you need the latest version of Raspbian, but I’d not played with my Raspberry Pi 2 board for a while, so the kernel and firmware were quite old:
So the first thing I had to do was to upgrade Raspbian. There are basically two options to upgrade, either downloading and dumping the latest Raspbian firmware image to your micro SD card, and update it from the command line, for example through SSH, and I went with the latter what :
This took several hours on my board, so in hindsight it may not have been the best options. In order to complete the update, I had to reboot the board, and could confirm the Linux kernel and Broadcom firmware had both been updated:
