Unable to get Matter sample running on the Adafruit Feather nRF52840 Express

[Chris Boyer]

Hello.

I've recently been trying to get my Matter application to run on an Adafruit Feather nRF52840 Express. I'm having trouble getting the application to fully run as it seems to get part way through the initialization stage and then completely stops. These are the logs I'ms seeing:

Everything under "End init CHIP stack" is my application specific code making use of an i2c temperature sensor.

I experience similar results when using an unmodified sample. When using the Matter Lock sample I get the expected logs on my nRF52840DK, and I see this when flashing to the Adafruit Feather:

I'm using my DK as the programmer for the Feather, and I have RTT for logging on the feather instead of UART. I also disabled OTA capabilities on the Feather since it doesn't have an onboard flash. If I had to guess, I'd imagine it's a configuration issue, but I'm not sure where to go with my debugging.

Thanks for any suggestions.

Hi,

I also disabled OTA capabilities on the Feather since it doesn't have an onboard flash.

Did you do this by selecting prj_no_dfu.conf as configuration file, or did you do it in some other way?

Does the Adafruit Feather nRF52840 Express have an external 32 KHz xtal? If not, please try adding the following to the project configuration:

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION=y

Can you test if you are able to run OpenThread and Bluetooth LE samples on the Feather?

Best regards,
Marte

For my custom application I created a modified build configuration:

CONFIG_CHIP=y
CONFIG_CHIP_ENABLE_PAIRING_AUTOSTART=y
CONFIG_CHIP_PROJECT_CONFIG="src/chip_project_config.h"
# 32768 == 0x8000 (example Product ID added temporaly,
# but it must be changed with proper PID from the list:

CONFIG_CHIP_DEVICE_PRODUCT_ID=32768
CONFIG_STD_CPP14=y

# Add support for LEDs and buttons on Nordic development kits
CONFIG_DK_LIBRARY=y

# Bluetooth Low Energy configuration
CONFIG_BT_DEVICE_NAME="MatterTemplate"

# Other settings
CONFIG_THREAD_NAME=y
CONFIG_MPU_STACK_GUARD=y
CONFIG_RESET_ON_FATAL_ERROR=n
CONFIG_CHIP_LIB_SHELL=y

# Disable NFC commissioning
CONFIG_CHIP_NFC_COMMISSIONING=n

CONFIG_USE_SEGGER_RTT=y
CONFIG_RTT_CONSOLE=y
CONFIG_UART_CONSOLE=n
# Disable Matter OTA DFU
CONFIG_CHIP_OTA_REQUESTOR=n

CONFIG_I2C=y

# Disable Matter OTA DFU
CONFIG_CHIP_OTA_REQUESTOR=n

However, when I was running the matter lock sample, I was using the pro_no_dfu.conf as my configuration file.

I believe it has an external 32 KHz crystal.

Is there a specific open thread or bluetooth sample you'd like me to try running? I wasn't able to get zephyr/samples/net/openthread/coprocessor, nrf/samples/openthread/coprocessor failed because they couldn't find the device definition:

I tried adding a adafruit_feather_nrf52840.overlay to the boards folder without luck. nrf/samples/openthread/cli did build and I was able to flash it to the device. I had to modify the the prj.conf to use RTT instead of UART, which leaves this as the final file:

In the RTT logs though, all I see is this, so I'm skeptical as to whether it's doing anything:
