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, 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.

Intercepting signals

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

All this points has been hardware reverse engineered from a CECHH02/DIA-001 motherboard
