== General Information ==


= Description =
Syscon is the main power controller chip. It is responsible for powering up the various power systems and for configuring and initialising the CELL, RSX and southbridge. It communicates with these devices via seperate SPI busses. There is external access by JTAG (Which appears to have been disabled after factory programming) and Serial.
The PS3 syscon is the main power controller chip of the PS3. It is responsible for powering up the main 12v rail of the [[Power Supply]] and various power systems by switching different [[Talk:Regulators|voltage regulators]] in the motherboard, and for configuring and initialising the [[CELL BE|BE]], [[RSX]] and [[South Bridge|SB]] via dedicated SPI buses.


The LEDs and buttons of the [[Switch boards|Switch board]] are connected to syscon, as well as the [[Cooling|fan/s]], buzzer, etc.
== Generation 1 ==
[[File:SYSCON_GEN1.JPG|thumb|Syscon 1st Generation (BGA Packaging)]]


The Syscon is a SoC and based on a ARM7TDMI-S (in the [[Mullion]] syscons) or a NEC 78K0R (in the [[Sherwood]] syscons) design. There is external access by "JTAG" (disabled from factory on retail models), an EEPROM programming interface (only on Mullion) and Serial (UART).
BGA Package : 200 Pins


<!--// Remote Power ON/OFF (from network, HDMI CEC commands, etc...) is managed by devices connected to the southbridge (ethernet/wifi/BT, HDMI controller, etc...) //-->
Pin's are labelled in the service manual for this generation


== PlayStation system controllers ==
== Generation 2 ==

* The SPC900 core was designed by Texas Instruments ([https://www.linkedin.com/in/hirakawa-katsunobu-55b09b2])
* ''CXP101064'', ''CXP102064'' are similar to CXP97 (''CXP971000'', ''CXP972032'', '''CXP973064''', ''CXP973F064''), the ''CXP103049'' matches no COTS because of its OCD support
** In-Circuit-Emulator: Mitek NICE-SPC970 ([http://www.hitechfacility.co.jp/details.php?id=E0001913]); Debug software: SVD970; Flash programmer: SFP-2
* A ''F'' inside the model name specifies that the IC contains flash memory.
** Mass-produced CXR/SW units don't have/use program flash memory for updates, instead an encrypted firmware patch is stored on the data-"EEPROM"
* CXR7 series uses Sony SR11 CPU (ARM7TDMI)
** Models with public datasheet: ''CXR702080'', ''CXR702F080'', ''CXR704060'' (datasheet: [http://www.alldatasheet.com/datasheet-pdf/pdf/294279/SONY/CXR704060.html 1])
* Prototype PS3 Syscon's:
** [[CXR713F120A]] Syscon used on (early) pre-release prototypes, e.g. [[CEB-2030]], [[DECR-1000]], [[DEH-H1001-D]], [[DEH-H1000A-E]]
** [[DEH-FH1500J-A]] with [[VERTIGO-02]] board and SW series prototype ''[[Media:DEH-FH1500J-A_-_VERTIGO-02_-_Syscon_Hardware.jpg|D79F0073]]''
** [[CBEH-H2001]] with [[SUR-00x#SURTEES-03|SURTEES-03]] board and SW2 series prototype ''D79F0086''
** [[DEH-ML00AK-G]] with MPX-001 (Prototype) board and SW3 series prototype ''[[Media:DEH-ML00AK-G_Board_4.jpg|D79F0123]]''

SCUARTD packets includes header of 0x3 bytes and optional payload (depending on the command).
 
Packet IDs are not important, they are used only by clients and processed by SCUART daemon. SCUART daemon opens terminal file /dev/ttyS0 and use it to send commands and receive responses.

=== Notes ===
 
* Some commands are unavailable on earlier firmwares, for example, tmpforcp is only supported on 1.3.3+.
* Some commands are divided into several strings, the first part (if exists) describes a command group, the second part describes the actual command and other parts describes command arguments.
* Real syscon commands have an ASCII form (a bold text in the 2nd column) instead of bytes above.
* Packet with ID *0x03* notifies syscon and calls SX program (based on ZMODEM protocol) to send firmware, syscon have custom or original implementation of RX program to receive firmware. An implementation of ZMODEM protocol used by Sony: http://oss.sony.net/Products/Linux/Others/Download/DECR-1000/mips_fp_le-lrzsz-0.12.20-devtool.1.src.rpm
 
A start of syscon's update procedure:
* A CP development tool includes several scripts which are participated in syscon update procedure. It starts after a CP update via ''update_syscon.pl'' perl script.
* This script checks the current syscon's firmware version. If it is in mask rom then it skips an update procedure, if not it checks major/minor/release parts of both versions and if a new version is applicable then it launches ''scfirmup'' utility and pass the firmware file path as an argument.
* ''scfirmup'' is a stupid tool which prepares a connection to SCUARTD and sends an update packet with a file path inside it. There is no need to comment it, here is reimplementation: http://pastie.org/private/6h8mfeoics4mdxear7ayg
 
A syscon's update operation in '''SCUARTD''' consists of following steps:
* 1. Check if ''SX'' program presents in ''/usr/bin/sx''. It should be a regular file.
* 2. Check if specified firmware file is a regular file.
* 3. Halt syscon by sending command '''halt'''  to UART, then wait some time until it prints ''HALT: OK''.
* 4. Reset syscon by sending byte ''0x30'' to GPIO register '''SC_PI0_DIPSW''', byte ''0x30'' to GPIO register '''SC_RSTX''', waiting 1 second and writing byte ''0x31'' to GPIO register '''SC_RSTX'''.
* 5. Get current syscon's firmwave version by sending command '''version''' to UART. After receiving it, look for a character after the first ''_'' (underscore) symbol from the left side of string and if it equals to the character ''b'', then proceed to the next step, otherwise go to the (8) step. (It is possible to patch this step to allow upgrading or downgrading at will)
* 6. Prepare syscon for an update by sending command '''firmud''' to UART, then fork the current process; the current process won't finish until a message ''Done'' from UART arrives (it is the end of update operation).
* 7. In the forked process start ''SX'' program and pass firmware file path to it. ''SX'' program reads firmware file and transfer each chunk of it to syscon.
* 8. After successful update operation reset syscon (a different way) by sending byte ''0x31'' to GPIO register '''SC_PI0_DIPSW''', byte ''0x30'' to GPIO register '''SC_RSTX''', waiting 1 second and writing byte ''0x31'' to GPIO register '''SC_RSTX'''.
 
Notes:
* It seems all scuartds checks firmware revision and probably syscon is updated only once (after factory).
* To be able to reflash it you need to patch ''SCUARTD'' or do a manual update without the use of ''SCUARTD''.
* You need to patch a single byte in ''SCUARTD'' to be able to flash any firmware (for example, to downgrade your syscon).

</syntaxhighlight>
 
* An actual firmware update process (without halting and resetting steps) takes about 1 minute.
* You cannot install a corrupted firmware with scfirmup unless you corrupt the header! It seems there is a hash of sorts (possibly of the plaintext) in the header preventing scfirmup from installing something corrupt
* Updating SYSCON requires the DECR to be in standby mode! You cannot update it while it is on.
* Corrupting the header and the body will make firmup install the SYSCON update anyways! be careful not to do it!
* Should you brick SYSCON, here's a patch to "unbrick" it, do not use it unless you brick it though!

You can attach a 3.3v TTL cable (LV-TTL) to the UART on syscon (UART0_TxD, UART0_RxD). Baud rate is 57600. There is a simple plaintext protocol involved. This varies on different syscon models. Example:
 
'''<command>:<hash>'''
 
Where the hash is the sum of command bytes & 0xFF.
 
You should terminate commands with \r\n, the syscon messages are only terminated with \n.

VERY IMPORTANT:
* Max size of a command is 11 characters, 16 if you count with C:<hash>:
* Sending a command with 11 chars results in NO OUTPUT
* Sending a command with more than 11 chars results in NG F0000002
* Max size of a command on DECR is 135, 140 if you count with C:<hash>:

= Testpads and alternative solder points =
*The identification of the syscon UART testpads can be made by grouping the motherboard models in a similar way we was doing with the [[Teensy%2B%2B_2.0#Schematics_by_motherboard_.28retail.29| layouts]] of the hardware flashers, there are 7 retail testpads layouts:
**Layout 1 = COK-001, COK-002 (fat, mullion, NAND)
**Layout 2 = SEM-001 (fat, mullion, NAND)
**Layout 3 = DIA-001, DIA-002 (fat, mullion, NOR)
**Layout 4 = VER-001 (fat, sherwood, NOR)
**Layout 5 = DYN-001 (slim, sherwood, NOR)
**Layout 6 = SUR-001, JTP-001, JSD-001, KTE-001 (slim, sherwood, NOR)
**Layout 7 = MSX-001, MPX-001, NPX-001, PPX-001, PQX-001, RTX-001, REX-001 (superslim, sherwood, NOR/eMMC)
 
== DIA-001 and DIA-002 ==
This points are availables to intercept signals by soldering wires, attaching probes, osciloscopes, etc... The photos are only orientatives to follow the traces, there's no need to remove the SYSCON to intercept this signals so can be done while its working
