Function Documentation

nxp_rtxxx_dsp_ctrl_disable()

static void nxp_rtxxx_dsp_ctrl_disable ( const struct device * dev )

inlinestatic

Stops (stalls) the DSP.

Parameters

dev	DSP device

nxp_rtxxx_dsp_ctrl_enable()

static void nxp_rtxxx_dsp_ctrl_enable ( const struct device * dev )

inlinestatic

Starts (unstalls) the DSP.

Parameters

dev	DSP device

nxp_rtxxx_dsp_ctrl_load_section()

static int nxp_rtxxx_dsp_ctrl_load_section ( const struct device * dev, const void * base, size_t length, enum nxp_rtxxx_dsp_ctrl_section_type section )

inlinestatic

Loads a specified image representing a specified section to a particular region in the DSP's memory.

Parameters

dev	DSP device
base	Base pointer of the image to load
length	Length of the image
section	Section type which specified image represents

Returns

int 0 on success, -EINVAL for invalid parameters, -ENOMEM for image bigger than the target region
