nrf5340 - peripheral-lbs issue

[pekon94]

Hello,

I am new with nordic boards. I am using an nrf5340-(P)DK.

I bulit and downloaded the perhipher-lbs sample successfully to the board.

However, when trying to discover the board using nrfconnect-mobile, I could not.

Hi, 

What is the board version on the white sticker? Are you using NCS v1.6.1?

Do you program with SES or West? If you are using SES, do you program the network sample from SES?

What is the status of the DK after loading the images? Do you see the LED 1 blinks with a period of 2 seconds, duty cycle 50% (the device is advertising)?

Regards,

Amanda

Hello,

the board version is: PCA10095, 0.8.0, 2020.24

I was using NCS version v1.4.0 but I updated to v1.6.1 and tried again with the same result.

I use the SES. I was trying with the application sample. When I try to download the network sample I get the following error in SES output:

1) Failed to Download application

2) Error during programm/erase phase

3) Please check Jlink-target connection

4) Illegal value 0x210052E8 written to register 66 (MSP_NS) ignored

Previously, when loading the app sample of peripheral_lbs there was no change in the status of the DK. The LED didn't start blinking.

Thank you for your support.

Hi Petros,

The board is PDK. It is only supported by v1.4.0. See this note.  

I would suggest you use west build to flash the network sample Bluetooth: HCI RPMsg as the known issue in the netcore as you see. 

You could run the command via the command prompt. 

locate under  v1.4.0\zephyr\samples\bluetooth\hci_rpmsg and execute

west build -b nrf5340pdk_nrf5340_cpunet && west flash --recover

Then load the application by SES. 

Or only execute west build and flash for the perhipher-lbs sample.

west build -b nrf5340pdk_nrf5340_cpuapp && west flash --recover

The network sample Bluetooth: HCI RPMsg is automatically added to all Bluetooth Low Energy samples in the nRF Connect SDK. When CONFIG_BT_RPMSG_NRF53 is set to y (the default), the build system automatically includes the sample as a child image in the nrf5340_pdk_nrf5340_cpunet core.

I am using Linux,

is the procedure the same?

I am running the command but it fails when trying to use the nrfjprog (step -- west flash: using runner nrfjprog). 

I have the nrfjprog installed, but I think I haven't done this step as mentioned in the "Set up the command-line build environment" instructions:

You must also make sure that nrfjprog (part of the nRF Command Line Tools) is installed and its path is added to the environment variables.

Hi, 

The procedure is the same.  

On Linux, use the Getting Started Assistant or follow the steps found on the Installing NCS manually page. Have a look at the Set up the command-line build environment doc.

Hello,

I have followed this procedure but don't know how to do the last step:

You must also make sure that nrfjprog (part of the nRF Command Line Tools) is installed and its path is added to the environment variables. The west command programs the development kit by using nrfjprog by default.

It is not described how to add the nrfjprog path to a (which) environment variable.

I update the link http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_installing.html#set-up-the-command-line-build-environment

Hello,

I am stuck at what variable to create for the nrfjprog directory path. 

How should this variable be named? 

By default when installed the nrfjprog, the directory was set to /opt/nrfjprog.

I just post again the error message I get when building (-- west flash: using runner nrfjprog
FATAL ERROR: runner nrfjprog received unknown arguments: ['--recover']) the v1.4.0\zephyr\samples\bluetooth\hci_rpmsg:

-- west flash: using runner nrfjprog
FATAL ERROR: runner nrfjprog received unknown arguments: ['--recover']

[Amanda Hsieh]

Are you able to to run: west build -b nrf5340pdk_nrf5340_cpunet && west flash?

-Amanda 

[pekon94]

Yes this is executed successfully

[Amanda Hsieh]

Are you able to flash without '--recover'?
