Syscon Hardware

Syscon 1st Generation (BGA Packaging)

Syscon is the main power controller chip. It is responsible for powering up the various power systems and for configuring and initialising the CELL BE, RSX and South Bridge. It communicates with these devices via seperate SPI busses. There is external access by JTAG (ARM7TDMI which is at factory disabled by blowing a fuse) and Serial.

Syscon UART

You can attach a 3.3v TTL cable (LV-TTL) to the UART on syscon. 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

Here are some of the commands/messages encountered:

Messages:
Power applied (standby mode)
OK 00000000:3A

Power on
# (PowerOn State):7F

Power off (Hard shutdown)
# (PowerOff State):DD

After Fan test:
# (PowerOff State) (Fatal):36

No text, invalid hash:
