How To JTAG Raspberry Pi 2 (Without custom kernel)
Welcome to MOV r0, and my first blog post. The goal of this article is to teach you how to JTAG the Raspberry Pi 2 without having to compile a custom kernel to enable the GPIOs to do JTAG. Let’s begin! The tools and equipment I’ll be using today are as follows: TIAO USB Multi-protocol JTAG adapter. This device is like a BusPirate on steroids. It’ll do everything. It’s got an FT2232H chip inside, and supports dual-MPSSE. That means we can use UART/JTAG simultaneously, or SPI1/SPI2, or SWD. It’s really an amazing device at a great price.
