Not to be confused with the New Nintendo 3DS which has many dissimilar components most notably the motherboard.
Nintendo 3DS can also refer to the Nintendo 2DS which shares almost every component with one less of each hinge, speaker, and D.
Power-up sequence
From power loss
This happens as soon as battery or charger voltage is applied to the system.
- Voltage regulation kicks in, the MCU gets powered
- The MCU boots up
- I2C lines are initialized
- Configuration resistors are scanned
- Power regulation is configured
- Battery presence detection is configured (independent of pins BAT+, BAT-, or the middle pin being shorted anywhere)
- Charger presence is detected
- Battery rejection is run
The system is ready for the handling of the Power button press, even if the configuration is invalid (shorted battery lines, lack of sufficient battery charge, battery is rejected, etc.).
Soft start
This happens when the press of the Power button is detected by the MCU.
- Do state vericiation of the hardware
- Battery rejection is run
- If the battery is rejected, do emergency shutdown
- If this is a kiosk unit, and charger *presence* is not detected, cancel the power sequence
- Battery rejection is run
- Change the Power LED animation to the fade-in pattern
- Configure voltage regulation for the SoC
- Take SoC out of reset (/RESET1 and /RESET2 are no longer active)
- The PLL eventually locks, and the ARM9 bootrom starts executing, shortly followed by the ARM11 bootrom
- Cryptographic things are initialized
- Boot devices are discovered
- First valid boot option is booted, or if none are valid, the infamous blue screen is displayed
