| 3 | Command line |
| 4 | -- |
| 5 | The MobiCore Daemon supports 4 command line options. It also displays them with the help option: |
| 6 | |
| 7 | # ./mcDriverDaemon -h |
| 8 | usage: ./mcDriverDaemon [-mdsbh] |
| 9 | Start MobiCore Daemon |
| 10 | |
| 11 | -h show this help |
| 12 | -b fork to background |
| 13 | -m IMAGE load mobicore from IMAGE to DDR |
| 14 | -s disable daemon scheduler(default enabled) |
| 15 | -r DRIVER load dyamic driver |
| 16 | |
| 17 | -b Forks the daemon to background |
| 18 | |
| 19 | # ./mcDriverDaemon -b |
| 20 | |
| 21 | Makes the daemon run in background and returns immediate control to the shell. No need to use shell forking with & |
| 22 | |
| 23 | -m Loads a mobicore image to DDR |
| 24 | |
| 25 | # ./mcDriverDaemon -m /data/app/mobicore.img |
| 26 | |
| 27 | Loads the mobicore.img to DDR and starts executing it. |
| 28 | |
| 29 | -s Disables NQ IRQ scheduler |
| 30 | |
| 31 | # ./mcDriverDaemon -s |
| 32 | |
| 33 | -r Loads dynamic driver at startup. The full path of the driver binary must be given, eg. /data/app/driver.drbin |
| 34 | |
| 35 | # ./mcDriverDaemon -r /data/app/driver.drbin |
| 36 | |
| 37 | Custom registry locations |
| 38 | -- |
| 39 | Registry fallback |
| 40 | |
| 41 | In case of a Device wipe in Android the /data/app/mcRegistry folder will be deleted with all it's contents. To overcome |
| 42 | this the daemon supports a fallback location(eg /system/app/mcRegistry): it first tries to load the trustlet |
| 43 | from /data/app/mcRegistry/[uuid].tlbin and if it fails then it tries to read the trustlet from /system/app/mcRegistry/[uuid].tlb |
| 44 | |
| 45 | Both paths are completely configurable for the Daemon using 2 environment variables:MC_REGISTRY_PATH and MC_REGISTRY_FALLBACK_PATH |
| 46 | |
| 47 | For example if you want to use /data/app/mcRegistry as the default path and /system/app/mcRegistry as the fallback path: |
| 48 | |
| 49 | $ export MC_REGISTRY_PATH=/data/app/mcRegistry |
| 50 | $ export MC_REGISTRY_FALLBACK_PATH=/system/app/mcRegistry |
| 51 | $ /data/app/mcDriverDaemon |
| 52 | |
| 53 | Custom authtoken path |
| 54 | -- |
| 55 | |
| 56 | The authtoken file is created at provisioning and is by default located in /data/app/mcRegistry/00000.authtoken |
| 57 | |
| 58 | Because a device wipe could delete this file and make MobiCore unusable a new environment variable has been added to change the |
| 59 | default behaviour: MC_AUTH_TOKEN_PATH |
| 60 | |
| 61 | $ export MC_AUTH_TOKEN_PATH=/efs |
| 62 | $ /data/app/mcDriverDaemon |
| 63 | |
| 64 | This would change the location of the authtoken file to /efs |
