SPI GPS still supported?

I see that the gps start command has arguments to use the SPI interface. Is this still supported? Can I connect to an external GPS using SPI or are only serial ports supported?

SPI is only used and supported for Linux boards. Which board do you want to use it with?

A ProfiCNC Black Cube. I have located SPI test points are on the bottom of the Carrier Board - I was wondering if this would be feasible to prototype out for a custom carrier board.

Ok, seeing in the rpi config the ‘gps start’ command gets the device path /dev/spidev0.0 which isn’t available on the nuttx builds. Thanks bkueng.
