LR1110 on nRF52840 board

[AndyM]

Hello
I have a custom board with LR1110 Lora radio
I'm getting errors that driver is not supported when I define the spi1 for it

    lora0: lora@0 {

        compatible = "semtech,lr1110"; <--Unknown node type "nordic,lr1110"

And even though there is the lr1110 directory under C:\ncs\v3.0.1\modules\lib\loramac-node\radio\lr1110 there is no driver code there

So what are my options?

How do I integrate it into the Zephyr driver ecosystem ? 
My goals is to use the Zephyr lorawan API 

Thanks

Hi Andy,

there is no driver code there

I can see driver code for my SDK install:

Maybe something went wrong in the installation?

Try to run "west update" again, and check the folder again.

I have the same set of files  - see below screenshot

The problem is that I cannot select "semtech,lr1110" in the "compatible" section when I define the lora0 dts node
The following semtech devices can be selected: sx1272,sx1261,sx1276 but there is no lr1110
How do I get around that?

Rajeev,

The SWDR006  driver also does not exist in the SDK, so could you please clarify your instructions


Thank you

When you say "cannot be selected", can you share the build logs with the error saying this?

[AndyM]

Sorry didn't make myself clear
This is what I'm referring to

Here are the errors I get in the bulid
I do have CONFIG_LORA=y

CONFIG_SPI=y

CONFIG_SPI_NRFX=y

CONFIG_SPI=y

in the prj.conf 

No SOURCES given to Zephyr library: loramac-node
