This tutorial follows a series from 'sprites mods'
|

[1](https://spritesmods.com/?art=hddhack&page=1) to attempt to reverse
|

engineer a hard drive controller board

# JTAG Hookup Process
|
||||
|
||||
The first step is to hook up wires to the JTAG pins of the hard drive
|
||||
controller board in question.
|
||||
|
||||
Fortuitously, the HDD board I have appears to have the same pinout as
|
||||
the one on Sprites Mods for the JTAG pins. This involved a fair bit of
|
||||
fine tip soldering to small pads and attempting to follow traces on a
|
||||
dense PCB. Pictures below

||||

||||

|
||||
|
||||
Once the pins were soldered (GND, TDI, TMS, CLK IN, and TDO), the ARM
|
||||
JTAG programmer had to get hooked up to the soldered wires.
|
||||
|
||||
The pinout of the JTAG programmer is oriented such that the power input
|
||||
on the bottom.
