demo app Bluetooth: Channel Sounding Initiator with Ranging Requestor produces no output

[Mike Wirth]

Built this Channel Sounding demo app with nRF54LM20-DK as target using VS Code with nRF Connect extension on M5 Mac running Tahoe 26.5.2 using nRF Connect SDK 3.3.1.  App built, compiled and flashed without error.

But app produces no UART output on either port 1 or 2.  Even checked RTT which, connected, but not output either.

Are there any special build settings that I'm missing?  Other issues?

TIA,

Mike

PS: Added the following lines to the prg.config file as recommended by the forms-completion AI here,

CONFIG_CONSOLE=y
CONFIG_SERIAL=y
CONFIG_UART_CONSOLE=y
CONFIG_LOG=y

But the output is still missing.  Checked the zephyr/.config file and the "UART" and "LOG" strings don't appear there.  Is there something wrong with my pro.connect settings?

Here is .hex you can try on your DK to see if you can see output. No changes to .conf files.

I can try yours on my DK to see if it produces output.

Thanks, MJJ, for the quick reply.  No joy after flashing your hex file (by drag and drop).  Produced the usual "Disk not ejected properly" msg.  But no serial output on the debug USB-C ports.
Hmm... Apple M5 USB ports?

Will try this on my old Mac.

No joy.  No serial output on old Mac either.  

With regard to the hex file I generated, I'm now getting the following error on build:

/Users/mike/Nordic/BLE_Channel_Sounding-3.3.1-orig/channel_sounding_ras_initiator/src/main.c:186: undefined reference to `cs_de_populate_report'

I'll have to go back and clean up the pro.conf additions I tried to make and recompile....
