How to Enter Service Mode (officially known as Manufacturing Mode) on PSP Go
Connecting a PSP Go multi-use connector plug to a TTL serial adapter:
- Pin 24 connected to any ground (see pin-out below for ground pins)
- Pins 14 and 17 connected together for k-line communication with your favorite 1.8v level serial adapter
- Serial adapter must have a 1n4148 diode with line (cathode) toward it's TX, other end (anode) tied to RX, and RX going to Go pins 14+17
- Ground connected between Go and serial adapter
- (optional) Pin 20 with 10K resistor to 5v power source and pin 22 directly connected to 5v power source
Plug in your serial adapter to PC and set up PySweeper with the correct COM port for your adapter and the option for service mode selected. Plug in modified multi-use connector to PSP Go while fully powered off (NOT in sleep mode), SYSCON will begin serial communication with your serial adapter and enter service mode.
Explanation of Pins used for Service Mode
- Pin 14 is PSP Go TX
- Pin 17 is PSP Go RX
- Pin 24 is SYSCON TOH0, enables serial communication when grounded
- Pin 20 is Cradle Power Detect, enables charging/power from pin 22
- Pin 22 is 5v in
