Upgrading the Chumby 8 kernel #ReverseEngineering #Linux #IoT
Doug Brown has been writing posts about upgrading a Chumby 8 Internet of Things terminal. The latest involves getting the reboot and poweroff commands working properly.
… in order to restart the Chumby, I had to physically press a button to power it off and again to power it back on. As you can imagine, this got old really fast during development. For that reason it was one of the earliest things that I got working.
Some detective work, digging in the Linux kernel code and writing an appropriate device tree overlay is all explained in detail.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
