1 | MobiCore Daemon in Android |
| 2 | --- | |
| 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 |
