Is there a Zephyr driver for X-NUCLEO-GNSS2A1?

[lastgame]

Hello All

 

I am using zephyr RTOS on NUCLEO-F767ZI board. 

I am considering using the NUCLEO-F767ZI board to use GNSS data.

Is there a Zephyr driver for X-NUCLEO-GNSS2A1?

Hello @lastgame 

As you may know, available shield drivers are listed in Zephyr> board> Shields 

for the X-NUCLEO-GNSS2A1 there are no developed drivers yet.

Hello Sarra

Thanks for the reply.

My initial requirements are...
The U-BLOX module(for getting GPS data) needs to be connected to the NUCLEO-F767ZI.

Q. What shield boards do I need for connecting U-blox module? (USB connection with power)

Q. To use that shield board, I don't need a driver for zephyr, right? It's needed for a simple connection.

Hello again @lastgame,

For any shield you want to use that's not already availble under boards>shields, you'll need to manually add the shield configuration files available under /boards/shields:

which are: 

•  shield.overlay : provides a shield description in devicetree format that is merged with the board’s devicetree before compilation.
• Kconfig.shield : defines shield Kconfig symbols that will be used for default shield configuration.
• Kconfig.defconfig: defines the default shield configuration 

For the connectors and the compatibility between the nucleo board and the module/shield, it should work without adding anything, just make sure that the board.dts includes a description of the connector you're going to use (Arduino connectors for hence: zephyr/boards/st/nucleo_f767zi/arduino_r3_connector.dtsi at main · zephyrproject-rtos/zephyr · GitHub) that's it for the Zephyr configuration part, for the U-blox module, I'm afraid I am not familiar nor used it in the past. 

Hope that helps!
