◆ internal_bring_up_capture_pipeline()

ra8_err_t internal_bring_up_capture_pipeline ( void )

static

Route the parallel capture pins and bind the CEU source and codec.

Runs after the sensor is streaming: routes the DVP pins away from their bring-up owner, then binds the CEU capture source and the passthrough JPEG codec.

Returns: Repository error code from the first failed step, or success.

Return values

k_ra8_ok	The capture pipeline is bound and ready to capture.
other	The pin-routing, CEU, or codec step that failed reported this.

Precondition: internal_bring_up_sensor has already completed successfully.; s_source, s_source_state, and s_codec are not concurrently used.

Postcondition: On success s_source and s_codec are initialized for capture.; On any failure the function returns before later steps run.

Note: Not thread-safe with concurrent capture or re-initialization.

◆ internal_bring_up_sensor()

ra8_err_t internal_bring_up_sensor ( void )

static

Bring the OV5640 sensor up to streaming hardware-JPEG mode.

Sequences clock start, board reset, SCCB bind, chip-id probe, and VGA-JPEG mode configuration, stopping at the first failure.

Returns: Repository error code from the first failed step, or success.

Return values

k_ra8_ok	The sensor is bound, probed, and streaming VGA JPEG.
k_ra8_err_hw_init_failed	The probed chip id did not match OV5640.
other	The board or sensor step that failed reported this code.

Precondition: The board camera pins and clock are not already owned by another user.; s_sensor is not concurrently accessed by another init or capture.

Postcondition: On success s_sensor_bound and s_sensor_streaming are both true.; On any failure the function returns before later steps run.

Note: Not thread-safe with concurrent sensor access.

◆ internal_report_capture_events()

void internal_report_capture_events ( void )

static

Report the CEU event mask observed by the most recent capture.

Silent when the CEU source cannot report an event mask, e.g. before any capture has run.

Precondition: The diagnostic console is initialized.; s_source_state was initialized by c6_cam_camera_init.

Postcondition: On success one ceu_events= field is emitted.; No static diagnostic state is modified.

◆ internal_report_jpeg_status_detail()

void internal_report_jpeg_status_detail ( void )

static

Report the OV5640 hardware-JPEG status block from the last capture.

No-op unless the last ra8_ov5640_jpeg_status_get succeeded, since the status fields are undefined otherwise.

Precondition: The diagnostic console is initialized.; s_last_jpeg_status was populated by the most recent capture attempt.

Postcondition: When s_last_jpeg_status_err == k_ra8_ok, every field of s_last_jpeg_status is emitted once.; No static diagnostic state is modified.

◆ internal_report_sccb_state()

void internal_report_sccb_state ( void )

static

Report the most recent SCCB transfer direction, register, and result.

Always emitted regardless of camera or sensor bring-up state, since a bring-up failure is exactly when this is most needed.

Precondition: The diagnostic console is initialized.; s_last_sccb_op, s_last_sccb_reg, and s_last_sccb_err describe one complete SCCB transfer attempt (or the cold-start "none" state).

Postcondition: One sccb_op=/sccb_reg=/sccb_err= triple is emitted.; No static diagnostic state is modified.

◆ internal_report_sensor_registers()

void internal_report_sensor_registers ( void )

static

Report the OV5640 clock and stream registers when the sensor bound.

No-op when sensor_bind never succeeded, since the registers would not be readable.

Precondition: The diagnostic console is initialized.; s_sensor was bound by a prior internal_bring_up_sensor call.

Postcondition: When s_sensor_bound, every diagnostic register in sensor_diagnostic_register_t is emitted once.; No static diagnostic state is modified.

◆ internal_reset_camera_diagnostics()

void internal_reset_camera_diagnostics ( void )

static

Reset every camera diagnostic and lifecycle flag to its cold state.

Runs first in c6_cam_camera_init so a re-init after a partial failure never reports stale SCCB or streaming state.

Precondition: No capture or diagnostic report is concurrently in progress.; Static camera state was previously left in a defined state (init or a prior failed init).

Postcondition: Every static diagnostic and lifecycle flag holds its cold-start value.; No hardware register or bus transfer is touched.

Note: Not thread-safe with concurrent capture or diagnostic reporting.

static

Locate the first complete JPEG payload in a captured span.

Validates the SOI prefix and returns the length through the first EOI marker.

Parameters

[in]	jpeg	Captured sensor byte span.
[in]	bytes	Available capture bytes.

Returns: Trimmed JPEG payload length.

Return values

0	The span lacks a valid SOI or complete EOI.
