Nora-B126

[Petar02]

Hi everyone,

I have a problem with flashing code to Nora-B126, when i press flash in Visual Studio Code everything works fine. I got: 

Parsing image file.
Verifying programming.
Verified OK.
Applying pin reset.
-- runners.nrfjprog: Board with serial number 1050249959 flashed successfully.

But on actual board nothing happens ( i flashed a simple ble code). Does anyone know whats the problem.

Here is my prj.conf 

CONFIG_BT=y
CONFIG_BT_PERIPHERAL=y
CONFIG_BT_ZEPHYR_NUS=n
CONFIG_BT_DEVICE_NAME="My_nRF_Device"

CONFIG_LOG=y
CONFIG_LOG_BUFFER_SIZE=16384
CONFIG_LOG_MODE_DEFERRED=y
CONFIG_LOG_PROCESS_THREAD_STACK_SIZE=4096
CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_500PPM=y

and also i have built it for nrf5340dk_cpuapp_ns.

Careful: The NRF5340 setup flashes empty net core image by default. Try to use one of the NRF BTLE samples, these should have correct net core setups for the sysbuild.

The _ns builds more stuff that may require a correct setup (trusted firmware etc). I recommend trying without ns first.

Thank you. You’re right , I had to build the hci_ipc sample separately for the network core, and I also needed to enable the internal oscillator in its prj.conf
