G720 android15 ，Why did SCP fail to open?

General Discussion

After enabling CFG_LSM6DSO_SUPPORT=yes, the SCP cannot start and keeps restarting. However, when CFG_LSM6DSO_SUPPORT is disabled, the SCP can start normally. SCP A is ready.
Could you please tell me if it’s a problem with my configuration or the driver?

Dear Customer,

Thank you for reaching out.

Based on your description that the SCP boots normally when CFG_LSM6DSO_SUPPORT is disabled, but experiences restarts when it is enabled, it strongly suggests that the issue is likely related to either the LSM6DSO configuration or the SCP-side driver initialization for the sensor.

To help us diagnose this further, please provide the following information and perform these checks:

Checks to perform:

  • LSM6DSO Presence: Please confirm whether the LSM6DSO sensor is physically present and correctly mounted on your board.
  • I2C Configuration:
    • What is the specific I2C bus number being used for the LSM6DSO?
    • What is the slave address configured for the LSM6DSO?
  • IRQ / EINT Configuration: Kindly verify the interrupt (IRQ) or external interrupt (EINT) configuration for the sensor. Incorrect settings here can prevent proper communication or cause system instability.
  • Sensor Power / Regulator Settings: Please confirm the power supply and regulator settings for the LSM6DSO. Insufficient or unstable power can lead to unexpected behavior.
  • Consistency between AP and SCP Settings: Ensure that the settings related to the LSM6DSO are consistent between the Application Processor (AP) side and the SCP side. Mismatched configurations can lead to initialization failures.

Logs to collect:

Please also collect and provide SCP logs, paying particular attention to the following events and data:

  • SCP Reset / Restart Events: Logs leading up to and immediately following any SCP resets or restarts.
  • Exception or Watchdog Timeout: Any log messages indicating exceptions or watchdog timeouts, which can pinpoint the cause of the restart.
  • LSM6DSO Initialization Flow: Detailed logs showing the entire initialization sequence of the LSM6DSO driver.
  • WHO_AM_I Read Result: The result of the WHO_AM_I register read from the LSM6DSO. This is crucial for confirming successful basic communication with the sensor.

If the SCP consistently restarts specifically when sensor communication fails, this could indicate a driver-side error-handling issue that needs to be addressed.
