  1. I wondered role of all pins from JL8506.
    What is role of each pin from JL8506?
  • PWR_EN_SYS, CPU_DET, RESET, PWR_INT, PWR_EN_SYS, PWR_LED
    This question is for If I removed JL8506 part on circuit.

  1. Is there “Always On” function in RK3288(Firefly)?
    “Always On” is stand by mode with the least standby power.

  2. If there is “Always On” in firefly, which pin is used for this function?

  3. How is reference circuit for Always On? Could you send reference circuit? Please add some comments for description.

  4. If we need Micom for “Always On”, Could you send recommended support list for Micom?

Thank you .

JL8506 pins such as PWR_EN_SYS, CPU_DET, RESET, PWR_INT, and PWR_LED are mainly used for power control, reset handling, CPU status detection, and LED indication. If JL8506 Crossy Road is removed, these functions may need external control logic or MCU support.
