OpenHarmony v4.0 Custom Board - SAMGR/Foundation Service Failure and bm Command Not Working

General
1

Hi Team,

We are working on a custom OpenHarmony 4.0 board bring-up and facing issues related to SAMGR, foundation service startup, and Bundle Manager execution.

During boot, SAMGR starts, but several foundation services fail to register/start correctly. As a result:

  • foundation services stop/crash

  • System Ability lookup fails

  • bm command is not working

  • IPC requests fail through Binder

Observed logs:

C01800/SAMGR: [SA Scheduler][SA: 5100] not in SA profiles
C01800/SAMGR: NOT found service : 5100
C01800/SAMGR: [SA Scheduler][SA: 5100] handle load event by check start
C01800/SAMGR: [SA Scheduler][SA: 5100] not in SA profiles

C01510/BinderInvoker: 124: SendRequest: handle=0 result = 3

C01800/SA_CLIENT: GetSystemAbilityWrapper:sa 5100 is not exist

C01800/SAMGR: [SA Scheduler][SA: 10] not in SA profiles
C01800/SAMGR: NOT found service : 10
C01800/SAMGR: [SA Scheduler][SA: 10] handle load event by check start
C01800/SAMGR: [SA Scheduler][SA: 10] not in SA profiles

C01510/BinderInvoker: 124: SendRequest: handle=0 result = 3

C01800/SA_CLIENT: GetSystemAbilityWrapper:sa 10 is not exist

Current Observations

We confirmed the following:

  • samgr process is running

  • foundation directories are present in source tree

  • bundlemanager sources are available

  • bundle-related shared libraries are present in /system/lib64

  • however, required System Abilities are not registered

bm command execution result:

# bm help

error: failed to execute your command.

Source Tree Status

Available:

foundation/systemabilitymgr
foundation/bundlemanager

Some framework directories are not present:

foundation/appexecfwk
foundation/aafwk
base/global/systemabilitymgr

Suspected Root Cause

Currently it appears that:

  • SA profiles are not being loaded/generated properly

  • foundation services are failing during startup

  • BundleMgrService registration is missing

  • product configuration may be incomplete for Standard System services

Questions

  1. Where are SA profiles generated and loaded from in OHOS 4.0?

  2. What are the mandatory services/configurations required for:

    • BundleMgrService

    • bm command

    • foundation service startup

  3. Is additional Standard System configuration required for custom board bring-up?

  4. Are there any reference product configs for enabling:

    • Bundle Manager

    • Ability framework

    • AppSpawn

    • SA registration

Any guidance regarding SA profile loading, foundation service startup, and Bundle Manager initialization would be very helpful.

Thanks
