I've connected up a GPS receiver using a connection to button 1 on the DT6CustomBoard as the PPS input.
All works if I press button 1 as an emulation of the pulse.
All works if I provide a programmable pulse once per second as long as the pulse is wider than 1ms.
But my Trimble GPS receiver provides a pulse that is 10uS wide.
I there some part of the circuit defeating this narrow pulse? Either on the DT6CustomBoard or on the DART-SOM?
Is it that LinuxPPS doesn't work with a true interrupt?
Any help would be much appreciated.
