PX4 external GPS not detected

Hello,

I currently working on a custom board(Zynq Ultra Scale chip) running PX4, I have been able connect thorugh ROS2 2 IMUs, but I have not been able to connect any GPS, I tried a PA1010D and a M10, I have been trying to do it through ROS2 as well, first using the vehicle_gps_position and sensor_gps subscribers, but it alwasy show never published on px4. Could someone have any experience or can give me any tips or something to test?

Im aware my board is not supported by px4, but what I did is mimic a rasberry pi board since runs linux as mine.

Thanks for reading me, hope you are having a great day
