Feature: GPS #4

Closed Nexolight closed 7 years ago

GPS doesn't work yet - no Investigations from my side so far.

Nexolight commented 7 years ago

This will be updated when I investigate more.

Current error message at boot:

[gpsdaemon_bool checkSystemCmd(pid_t)]run shell script fail, script exit code: 1

Some documentation

This is what the gpsdaemon service does:

: [gpsdaemon]Open /proc/device-tree/gps_power/broadcom_config,ic_type success!

And afterwards it seems that only one out of 3 different services available in the roms start up. The other ones fail eighter because of a SEGV (invalid config) or because one is already running. The one running is the one named after the config. I guess that's intentional.

At the moment it looks like all the services do work fine but I don't get any gpsfix or any obvious error message

Just tons of these:

02-06 21:35:58.955  3004  3004 D gpsd    : WakeLock(Acquire,GPSD)
02-06 21:35:58.956  3004  3004 D gpsd    : WakeLock(Release,GPSD)
02-06 21:35:59.671  3004  3004 D gpsd    : WakeLock(Acquire,GPSD)
02-06 21:35:59.671  3004  3004 D gpsd    : WakeLock(Release,GPSD)

Also this sometimes appears in the log:

02-06 21:39:34.894  6142  6142 E gpsd    : Cannot rename file [] suffix to [.a.txt]
02-06 21:39:34.894  6142  6142 E gpsd    : Cannot rename file [] to [], errno=2

My bad I got a tipp from an XDA member (surdu_petru) to rename the file system/lib64/hw/gps<gpsdameon>_default.so to system/lib64/hw/gps.hi3635.so

I put it in the wrong folder before. With that one and some other files GPS does work now (6bb1533c32a4b9bd2c9f7e3be52519fe6c1de55e)
