DMIC PDM-RX Sample Application

Description

The DMIC PDM-RX sample application demonstrates audio capture using the Digital Microphone (DMIC) interface on supported boards. It validates the end-to-end PDM receive path, including:

  • DMIC clock and I/O configuration

  • Channel configuration and gain/boost setup

  • FIFO and DMA capture paths

  • Captured PCM data verification

The sample supports multiple capture modes:

  • Blocking read: FIFO-based synchronous capture

  • Non-blocking read: Interrupt-driven FIFO capture

  • DMA-based capture: Continuous capture through DMA

  • DMA non-blocking read: Callback-driven DMA capture

During execution, the app logs initialization status, configuration details, and capture results so that bring-up and data-path issues are easier to diagnose.

The application follows the common source layout used by driver samples:

  • Common sources: main.c, dmic_sample_app.c, dmic_sample_app.h (app root)

  • Defconfigs: configs/

  • Board-specific hardware setup: hw/<BOARD>/ (for example hw/SL2610_RDK/)

The app can also be built as a standalone application repository by setting SRSDK_DIR to the SDK root.

Supported Boards

This application supports:

  • SL2610_RDK

Prerequisites

Choose one setup path:

Test Case Selection

Before building, select the testcase defconfig for the capture mode you want to validate.

You can:

  • Pick a defconfig from configs/

  • Run:

    make list_defconfigs

Available DMIC defconfigs (SL2610 RDK):

  • sl2610_rdk_cm52_dmic_defconfig: FIFO blocking read mode

  • sl2610_rdk_cm52_dmic_nonblocking_defconfig: FIFO non-blocking mode

  • sl2610_rdk_cm52_dmic_dma_defconfig: DMA blocking capture mode

  • sl2610_rdk_cm52_dmic_dma_nonblocking_defconfig: DMA non-blocking capture mode

Building and Flashing using VS Code

Use the VS Code flow in:

Build (VS Code):

  1. Open Build and Deploy -> Build Configurations.

  2. Select dmic_sample_app in Project Configuration.

  3. Select the required defconfig.

  4. Build with Build (SDK+Project) for first build, or Build (Project) for incremental rebuilds.

Flash (VS Code):

  1. Generate the image (sysmgr.subimg.gz) using the standard SL2610 image generation flow.

  2. Open Image Flashing (SL2610).

  3. Select Flash Target as M52 Image.

  4. Select generated image path.

  5. Start flashing.

Building and Flashing using CLI

Use:

Build (CLI):

  1. First build:

    cd <sdk-root>/examples/driver_examples/dmic_sample_app
export SRSDK_DIR=<sdk-root>
make <app_defconfig> BUILD=SRSDK

  2. Rebuild after app-only changes:

    cd <sdk-root>/examples/driver_examples/dmic_sample_app
export SRSDK_DIR=<sdk-root>
make build

Build outputs:

  • ELF: <app-dir>/out/<target>/release/<target>.elf

  • App-local SDK package: <app-dir>/install/<BOARD>/<BUILD_TYPE>/

Flash (CLI):

  1. Build bootloader image:

    cd <sdk-root>
export SRSDK_DIR=<sdk-root>
make <SL2610_Bootloader_defconfig> BOARD=<BOARD>
make astrasdk

  2. Generate system sub-image:

    cd <sdk-root>/examples/driver_examples/dmic_sample_app
export SRSDK_DIR=<sdk-root>
make imagegen

  3. Flash image to target (see SL2610 CLI guide above).

Running the Application

  1. Press RESET after flashing.

  2. Open Serial Monitor on UART logger port (115200, 8N1).

  3. Verify logs for:

    • DMIC init/config success

    • Selected capture mode

    • Capture start/complete or error details

Large Capture and Audio Export (JTAG + Memory Dump + Audacity)

The same image can be used for both capture methods:

  • JTAG capture: dump full PCM buffer from memory

  • UART capture: capture frame/sample logs from serial console (for users without JTAG).

Choose the method that matches your setup.

1) Method A: JTAG full-buffer capture

This is the recommended method when JTAG is available.

  1. Flash/boot the default CI image and run the sample app until DMIC capture completes.

  2. Boot the default image over USB:

python <path>/usb_boot_tool.py --op run-spk --spk tools/usb_boot_python_tool/USB_BOOT_TOOL/spk.bin --keys tools/usb_boot_python_tool/USB_BOOT_TOOL/key.bin --m52bl tools/usb_boot_python_tool/USB_BOOT_TOOL/m52bl.bin

  1. Start OpenOCD:

openocd -f "tools/openocd/configs/Klamath_Jlink.cfg"

  1. Connect with GDB in another terminal:

arm-none-eabi-gdb

Then run:

target extended-remote:3333

Windows note:

  1. After capture completion, halt CPU in debugger and run:

dump binary memory dmic.bin 0xBA100000 0xBA2D4C00

dump binary memory <file> <start_addr> <end_addr> uses address range, not size:

  • Start address: 0xBA100000

  • End address (DMIC_CAPTURE_TOTAL_BYTES): 0xBA2D4C00

  • Dumped bytes: 0xBA2D4C00 - 0xBA100000 = 0x001D4C00

Captured data buffer start symbol:

  • __img_buff_start

2) Method B: UART frame/sample capture (No JTAG)

Use this method if JTAG is not available.

  1. Flash/boot the same default CI binary.

  2. Open serial monitor on UART logger port (115200 8N1).

  3. Reset the board and wait for capture completion logs.

  4. Collect UART output starting from:

    • DMIC first 480 samples: index,raw32_hex

    • Next lines are samples in index,0xXXXXXXXX format.

Notes:

  • This UART path captures logged samples/frames, not a full memory binary dump.

  • UART sample dump is disabled by default. Enable CONFIG_APP_DMIC_UART_DUMP=y to print samples.

  • Default sample log count is 480 (DMIC_PRINT_SAMPLE_COUNT in dmic_sample_app.c) when UART sample dump is enabled.

  • Increase DMIC_PRINT_SAMPLE_COUNT and rebuild if you need more UART samples.

Optional: Print buffer address range on UART/logger

If you want the runtime capture buffer address in UART logs, add a log in examples/driver_examples/dmic_sample_app/dmic_sample_app.c after capture size is known:

LOG_INFO(LOG_MOD_DMIC,
         "[APP][DMIC] capture buffer: start=%p end=%p bytes=%u\n",
         (void *)data_buff,
         (void *)(data_buff + DMIC_CAPTURE_TOTAL_BYTES),
         (unsigned int)DMIC_CAPTURE_TOTAL_BYTES);

Notes:

  • data_buff maps to linker symbol __img_buff_start.

  • On SL2610 CM52, __img_buff_start is defined in linker script (soc/SL2610/cm52/config/sl2610_cm52_hw_gcc_arm.ld) and is currently 0xBA100000.

3) View the dump in Audacity (Import Raw Data)

  1. Open Audacity -> File -> Import -> Raw Data….

  2. Select dumped file: dmic.bin.

  3. In the import dialog, set:

    • Encoding: Signed 32-bit PCM

    • Byte order: Little-endian

    • Channels: 2 Channels (Stereo)

    • Start offset: 0 bytes

    • Amount to import: 100%

    • Sample rate: 48000 Hz

  4. Click Import.

Reference screenshot:

Audacity Import Raw Data Settings

4) Increase capture size

In dmic_sample_app.c, update capture constants as needed:

  • DMIC_CAPTURE_DURATION_SEC

  • DMIC_CAPTURE_SAMPLE_RATE_HZ

  • DMIC_CAPTURE_CHANNEL_COUNT

Current capture buffer size in bytes is:

DMIC_CAPTURE_TOTAL_BYTES = sample_rate * duration_sec * channels * sample_bytes

In the current sample app configuration, each sample word is stored as 32-bit.

5) Tune capture level (volume/gain/boost) and filter settings

Use the sample-app knobs in examples/driver_examples/dmic_sample_app/dmic_sample_app.c:

  • Per-channel gain:

    • DMIC_CH0_GAIN_SETTING

    • DMIC_CH1_GAIN_SETTING

  • Per-channel boost:

    • DMIC_CH0_BOOST_SETTING

    • DMIC_CH1_BOOST_SETTING

  • Channel/filter config:

    • adc_cfg.enable_hpf

    • adc_cfg.hpf_cutoff_freq

    • adc_cfg.enable_low_power

    • adc_cfg.enable_ll_filter

Current defaults are:

  • Gain: DMIC_GAIN_0DB (both channels)

  • Boost: DMIC_BOOST_0DB (both channels)

  • HPF: disabled (enable_hpf = false)

Supported gain/boost enums are defined in drivers/dmic/dmic.h:

  • Gain range: DMIC_GAIN_NEG_3DB to DMIC_GAIN_POS_3DB

  • Boost range: DMIC_BOOST_0DB, DMIC_BOOST_6DB, DMIC_BOOST_12DB, DMIC_BOOST_18DB, DMIC_BOOST_24DB

Example (louder input with moderate headroom):

#define DMIC_CH0_GAIN_SETTING   (DMIC_GAIN_POS_1DB)
#define DMIC_CH0_BOOST_SETTING  (DMIC_BOOST_6DB)
#define DMIC_CH1_GAIN_SETTING   (DMIC_GAIN_POS_1DB)
#define DMIC_CH1_BOOST_SETTING  (DMIC_BOOST_6DB)

Notes:

  • Increase in small steps (for example +1 dB gain or +6 dB boost per iteration).

  • If clipping/distortion appears in Audacity, reduce boost first, then gain.

  • Boost applies large coarse steps; gain is finer control.

6) Tune sample rate / format for Audacity import

These app Kconfig options control capture format:

  • CONFIG_APP_DMIC_SAMPLE_RATE_HZ

  • CONFIG_APP_DMIC_CAPTURE_CHANNEL_COUNT

    • Use 1 for mono capture

    • Use 2 for stereo capture

After changing them, ensure Audacity import settings match exactly:

  • Sample rate = CONFIG_APP_DMIC_SAMPLE_RATE_HZ

  • Channels = CONFIG_APP_DMIC_CAPTURE_CHANNEL_COUNT

  • Encoding = Signed 32-bit PCM (sample app fixed at 32-bit capture)

Sample Output

UART Dump Disabled (Capture Verification)

When CONFIG_APP_DMIC_UART_DUMP=n, UART sample lines are not printed. Capture is still valid, and full audio extraction can be done using JTAG memory dump.
