We’ve long been fans of the homebrew work done with XBMC on the original Xbox and hope that advances like this will lead to that end. Exploiting this hack makes it possible to boot a Linux kernel in about five seconds. In case you missed it, the JTAG hack is a way to run homebrew code on an Xbox 360. Xbox-scene reports that a new hack called freeBOOT v0.01 allows the Xbox 360 to upgrade to the newer kernels, but allows the option of rebooting to an older kernel in order use the JTAG exploit and gain access to the hardware. There has been another development in the never-ending battle that is Microsoft trying to keep its gaming system closed to unauthorized use.

We had some trouble finding an actual picture of this hardware. So far the list of programming targets includes STM32, LPC1000, LPC900, STM8, AR8, MSP430, and a few others. Obviously this should be able to program anything that works with the JTAG protocol, but the script adapts it to work as an In System (or In Circuit) Programmer too. With a bit of help from the software it has been turned into a programmer for ten different types of hardware. Above you see the Nano version which has a 10-pin JTAG connector, but there is also a 20-pin option on the Handy model. Versaloon is an open source, USB connected project, that centers around an STM32 processor and provides a standard JTAG pinout.

He found that this method slows the process down to an unbearable 5-minutes. It works well via the serial port, but he did try programming with a USB-to-Serial dongle. You can use this along with a programming application that whipped up using Visual Studio. There is also an LED for each data signal to give some feedback if you’re having trouble. Instead, uses Zener diodes and voltage dividers to make the conversion. Commercial programmers use a level convert IC to take care of this for you, but that doesn’t mesh with the cheap goal of this project. But the problem is that an RS232 serial port operates with 12V logic levels and the JTAG side of the programmer needs to operate with the logic levels native to the device you’re programming. This method requires only four signals (TDI, TMS, TCK and TDO) plus ground. JTAG is one of the options and here’s a cheap method that uses the serial port ( translated). If you’re planning to do some hacking with CPLD or FPGA chips you’ll need a way to program them.
