No SOURCES given to Zephyr library

[ALEJANDRO_CEIT]

We have a custom nRF9160 board in a dedicated directory (out-of-tree board). It is a near copy of the nrf9160dk_nrf9160 folder with hardware changes and additions.We are now trying to implement Serial LTE Modem with the custom board in the build configuration but is not compiling giving the error:

No SOURCES given to Zephyr library: drivers__console

Excluding target from build.

When building for the nrf9160dk_nrf9160_ns there are no errors.

I went over the files several times and do not see the difference but there must be something.

My compilin log:

nrf_custom_log.zip

My board folder:

nrf9160_sica_b1.zip

My project:

3618.serial_lte_modem.zip

Sorry but I have spent hours and cannot see the difference.

Thanks for your help!

Hi Alex,

I did copy and rename to your files in the following way.

nrf9160dk_nrf9160->custom_board_nrf9160

NRF9160DK_NRF9160->CUSTOM_BOARD_NRF9160

I got the following custom board configuration.

5488.custom_board_nrf9160.zip

In the SLM board folder, do same and get the following files.

custom_board_nrf9160_ns.overlay

custom_board_nrf9160_ns.conf

I have no problem to build the project.

Hi Charlie,

I followed your steps and I'm able to compile but I got some weird warnings that I don't understand, here is the compiling log:

custom_log_3.zip

Other problem is when I flashed my custom board I can't communicate my stm32 micro with the nrf9160 module via uart.. but when I flashed my nrf9160DK with this build I can communicate using terminal through FTDI wire put in the same uart pins..

Here is the schematic of my custom board:

schematic_custom_board.zip

is something wrong in the design?

thanks for your help!

Regards, Alex

[Hung Bui]

Hi Alex, 
Charlie is out of office for a few days. I will take over in the mean time. 
Could you please upload a higher resolution of the schematic ? Preferably as pdf file instead of png. 

Please give more info about the code Charlie provided. Besides the warnings do you have any issue , does it work as it should ? 

[ALEJANDRO_CEIT]

Hi Hung, 

thanks for your response. Here si the full schematic:

DFR8RAILOG_WNODE_v0.pdf

The solution that Charlie provided working with the nrf9160DK but not with my Custom board. I'm trying to communicate the nrf9160 SIP with STM32 MCU via uart2 but is not working and I think there something that I'm missing..

Here are my custom board files:

2273.nrf9160_sica_b1.zip

0844.custom_board_nrf9160_ns.conf

6283.custom_board_nrf9160_ns.overlay

I need to do a field test using nrf9160 LTE communications next week, so I appreciate any help.

Regards, 

Alex

[Hung Bui]

Hi Alex, 

Have you verified that there is no problem with the hardware ? 

Have you tried to toggle the uart2 pins as GPIO pins ? Just do a quick test if you can change the level of the pins. 

If it work, please try to test with a simple UART sample and use a logic analyzer to check if you have correct UART output on the pins. 
After that you can start to try testing with the serial lte modem sample.
