After a little bit of debugging, I would say that Adafruit has mixed something up. External flash doesn't seem to be "gd25q16", or at least JEDEC ID of it doesn't match. We expect "jedec-id = [ c8 40 15 ];" but it's actually "jedec-id = [ ef 40 15 ];". Which is actually Winbond W25Q16JV.

Hello,

Thank you for sharing more details about your setup.

[quote user="Amit Twati"] To ensure the board is functioning properly, I tested it with a non-Matter application like Blinky[/quote]

Good to know that the board can run simple applications.

To see if the radio is also working, please build and run the Bluetooth LBS or Thread: CoAP Server on the Feather as well. For testing the CoAP server, run the CoAP Client on your nRF52840 DK.

[quote user="Amit Twati"]For this Matter Template app sample, I’ve kept the default prj.conf file from the template[/quote]

The default prj.conf will have UART as the logging method. To be able to get logging over RTT, you need these lines in the configuration file:

CONFIG_USE_SEGGER_RTT=y
CONFIG_RTT_CONSOLE=y
CONFIG_UART_CONSOLE=n

Best regards,

Maria

Hello Maria,
Thank you for your response.

Here's some additional context about my setup and the issue:

I’m using a J-Link device to connect the Adafruit Feather nRF52840 board to my Mac via SWD pins, and I’ve confirmed that the connection is stable. I’ve also tried using an nRF52840DK as a J-Link, but the results were the same. The Adafruit board is unmodified, but I did attempt to enable USB CDC ACM as described in the linked post. Unfortunately, even after following those steps, the device doesn’t appear as /dev/ttyACM* on my Mac.

I’m using nRF Connect SDK version 2.8.0 and toolchain version 2.8.0. To ensure the board is functioning properly, I tested it with a non-Matter application like Blinky, which works as expected and shows logs via RTT. For this Matter Template app sample, I’ve kept the default prj.conf file from the template

Hello,

Have you connected a J-Link device to the feather board to make reading the serial data possible? Alternatively, have you added USB CDC ACM to the board like described in this post?

For the most relevant support, please also share which nRF Connect SDK version you are using.

Best regards,

Maria
