==== Winbond 25X16AVSIG (SPI Flash 16Mbit) ====
The IC designation on the board of the cobra dongle is U1.
{{Template:Winbond 25X16AVSIG}}
On the Cobra Dongle, pin 3 of the EEPROM is tied to VCC. Lifting this Pin from the board and tieing it to ground '''should''' prevent the flash from being erased.
=====Roles=====
Drives data to and from the Winbond flash chip.
====Cobra Test Points====
<div style="float:right">[[File:Cobra-TESTPOINTS.jpg|200px|thumb|left|Cobra - Testpoints to Winbond SPI flash]]</div><BR/>
There are test points that map out the Winbond flash shown in the diagram to the right.
==== DG/PS3/PC Selection switch ====
There is a switch that switched between Downgrade, PC and PS3 modes of the dongle.
When facing the switch, with the USB Plug to the left the pins are labeled 1 to 4 in the table below:

In case you wanted a simple guide howto run Cobra without a dongle, look here: http://www.ps3hax.net/showthread.php?t=67286

This article is marked for rewrite/restructuring in proper wiki format.
You can help PS3 Developer wiki by editing it.

Description[edit | edit source]

Dongle is DRM to make sure you have the dongle, the firmware 'special' functionality will not work without it.
Hardwarewise, there are many simularities with ReDRM / Piracy dongles like PSJB2/TrueBlue


The Ps3Cobra implements syscall 8 and moves syscall 0 into the payload. It does some heavy patching on Lv2 code

Winbond 25X16AVSIG (SPI Flash 16Mbit)[edit | edit source]

The IC designation on the board of the cobra dongle is U1.

8-pin TSSOP
Winbond 25X16A
SOIC-8 pinout

W - Winbond
25X - SPI Flash with 4KB sectors/64Kbyte blocks, dual output
16A - 16Mbit / 2M-byte
V - Supply Voltage 2.7 to 3.6V
S - Package Type : 8pin SOIC 150-mil
I - Temperature Range: Industrial (-40'C ~ 85'C)
G - Environment: Green Package (Lead-free, RoHS Compliant, Halogen-free (TBBA), Antimony-Oxie-free)

datasheet: W25X16A.pdf (1.3 MB) / https://web.archive.org/web/*/http://ps3devwiki.com/files/reDRM/TrueBlue/Datasheets/W25X16A.pdf
Note: can use Bus Ninja or Bus Pirate and FlashROM - ISP is possible, so long as no other devices on the SPI bus are trying to access the device (in that case, you might want to cut Vcc to the FPGA or the regulator for it).

Pin Usage I/O Remarks
1 /CS I Chip Select (high=deselect, low=select)
2 DO O Data output
3 /WP I Write Protect (active low)
4 GND Ground
5 DIO I/O Serial data input/output
6 CLK I Serial Clock
7 /HOLD I Hold (high=normal/resume, low=hold/pause)
8 VCC Vcc (min 2.7-max 3.6V @ Fr0 75MHz / min 3.0-max 3.6V @ Fastread Fr1 100MHz)

On the Cobra Dongle, pin 3 of the EEPROM is tied to VCC. Lifting this Pin from the board and tieing it to ground should prevent the flash from being erased.

Roles[edit | edit source]

Drives data to and from the Winbond flash chip.

Cobra Test Points[edit | edit source]

Cobra - Testpoints to Winbond SPI flash


There are test points that map out the Winbond flash shown in the diagram to the right.

DG/PS3/PC Selection switch[edit | edit source]

There is a switch that switched between Downgrade, PC and PS3 modes of the dongle.

When facing the switch, with the USB Plug to the left the pins are labeled 1 to 4 in the table below:

When in PC Mode, Pins 1 and 2 are shorted. When in PS3 Mode, Pins 2 and 3 are shorted. When in DG Mode 3 and 4 are shorted.
Pin Usage Connects to Remarks
1 PC Position GND A resistor is placed, by hand, between this pin and GND after the board is manufactured.
2 PC/PS3 Position AVCC (atmega 27) + Winbond /WP (PIN 3) Ties to Pin 27 of atmega16 (AVCC) and /WP of Winbond Flash
3 PS3/DG Position TOSC2 of the Atmega (Pin 26) ???
4 DG Position GND A resistor is placed, by hand, between this pin and GND after the board is manufactured.
