HI_MIPI_CONFIG_SENSOR_CLOCK

The Atlas 200/300/500 Inference Product does not support this command word.

The Atlas Training Series Product does not support this command word.

Description

Configures the input clock frequency of the sensor.

Prototype

#define HI_MIPI_CONFIG_SENSOR_CLOCK _IOW(HI_MIPI_IOC_MAGIC, 0x17, sns_clk_cfg_t)

Parameters

  • HI_MIPI_IOC_MAGIC: magic number of the MIPI RX ioctl command.
    #define HI_MIPI_IOC_MAGIC 'm'
  • 0x17: indicates the command word function and configures the clock frequency input to the sensor.
  • sns_clk_cfg_t: clock configuration information input to the sensor in slave mode.

    When the sensor works in slave mode or requires the Ascend AI Processor to provide a clock, this command needs to be called in the process to configure the clock configuration information input to the sensor.

Returns

  • 0: success
  • -1: failure

Considerations

Before configuring the sensor clock, run the HI_MIPI_DISABLE_SENSOR_CLOCK command to disable the sensor clock.
