Hard disk hacking – hooking up JTAG #ReverseEngineering @SpritesMods
Sprite_tm looks into the hackability of hard drives by connecting to the JTAG debug header on the circuit board.
The Western Digital controllers seem to have an ARM-core that’s accessible over the JTAG-port. (Also) these hard disks usually have a serial port, which is usually unused but could be useful for debugging my hack.
See the detective methodology used to get information from the interface and more in the multipart series here.
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.
