I just got my Sure GPS board, and harware wise it seems to work fine. But i fail to get a PPS from the raspi side.
I have recompiled the kernel, installed the modules, and PPS support shows up in dmesg: root@pi:/dev# dmesg | grep PPS [ 13.660962] pps_core: LinuxPPS API ver. 1 registered I do not see a line for the specific PPS device, even though I have loaded the module: root@pi:/dev# cat /proc/modules | grep pps pps_gpio 2219 0 - Live 0xbf076000 pps_core 7978 1 pps_gpio, Live 0xbf070000 There is no PPS device: root@pi:/dev# ls /dev/*pp* /dev/ppp /dev/mapper: control I did compile the PPS driver with debugging enabled, but I did not find out how to enable more verbose output. Any hints what I am doing wrong? The PPS output is hooked up, the blue LED is blinking, I have measured a pulse with my voltmeter, so it seems to be a software-side problem.
