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

I hope this helps: https://github.com/Lora-net/SWDR006. I don't see a direct support here and also in Cmake

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.

Sigurd

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

[Sigurd Hellesvik]

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
