# 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.
